Can I Prevent Skin Cancer?

Categories: BLOG, Skin Cancer, Tips and Tricks - Tags: , , , , , , , , , , ,

An epidemic is sweeping our nation – skin cancer is on the rise with over 4 million new cases diagnosed every year in the United States.  The vast majority of these skin cancers are of the basal and squamous cell carcinoma type. These types of skin cancer have an indisputable link with sun exposure. Melanoma type skin cancer is also increasing- this more deadly subtype has both a sun induced and genetic component. As a society, we are now quite conscious about sunscreen. Are there other things we can do to help prevent this epidemic of skin cancer?

  1. Nicotinamide: Also known as vitamin B3 – nicotinamide has been shown in several trials to reduce the incidence of non-melanoma skin cancer. A trial of 386 Australian patients who had more than 8 skin cancers over the past 5 years showed that those who took nicotinamide had a 23% reduction in skin cancers compared to those who took placebo.  Furthermore, those in the nicotinamide group had a 13% reduction in precancerous lesions known as actinic keratoses.  Not only is nicotinamide effective, but it is quite affordable (typically about 6 cents per day) and well tolerated, with no major adverse effects.  Here is a link to a previous Tareen Dermatology blog post on nicotinamide: http://www.tareendermatology.com/cms/2015/06/29/a-pill-today-to-keep-cancer-away/

  1. Polypodium leucotomos: Also known as the calaguala plant, this product is commercially available in a standardized product called Heliocare. The evidence for this plant extract is that it acts as an antioxidant- protecting the skin against free radical damage that stimulates mutations and skin cancers. Since free radicals also contribute to skin aging, Heliocare is also thought to have a cosmetic benefit!

  1. Milk thistle: Also known as Silybum marianum, this plant is still being studied to reduce skin cancer. In animal studies it does have a protective benefit.  Furthermore, it is safe and inexpensive.

At Tareen Dermatology in Roseville, Minnesota we hope that all of our patients both protect their skin with sun protective clothing and sunscreen as well as prevent skin cancer with these great natural strategies!

Excessive sweating- a stressful issue in teens and young adults

Categories: BLOG, Dermatological Conditions, Health, Tips and Tricks - Tags: , , , , , ,

According to a recent survey by the American Academy of Dermatology, approximately 20% of teens and young adults suffer from excessive, uncontrollable sweating. This condition, known as hyperhidrosis, can interfere with daily life and cause anxiety.

According to the study, the average onset of hyperhidrosis was 11 years of age, although younger children can also be affected. Many different areas can be affected- although axillary areas and palms and soles are most common.

The good news is that there are effective treatment options for hyperhidrosis:
1- First line therapy can range from topical over the counter “clinical strength” antiperspirants to prescription strength topicals such as Drysol. A great tip is to apply these topicals at night, in order to form a plug over the sweat glands while one sleeps. In addition, if the palms or soles are involved, one may soak the areas with the antiperspirant for 5-20 minutes.

2- Second line therapy includes oral anticholinergic medications. Because side effects may occur, these agents must be prescribed and monitored by your doctor. The good news is that numerous studies conducted in children as young as 7 years old have shown these medications to be safe with no long lasting adverse effects.
3- Other therapies include Botulinum toxin, microwave therapy of affected areas and even neurosurgery to block nerve stimuli. Luckily, most kids are controlled with safer options.
At Tareen Dermatology, we are alert to the needs of our patients- from kids to adults- suffering from hyperhidrosis. If this debilitating condition affects you, Board certified Minnesota dermatologist Dr. Mohiba Tareen and her colleagues are able to help!

Creams for Wrinkles

Categories: Acne, BLOG, Cosmetic, Dermatological Conditions, Tips and Tricks - Tags: , , , , , , , ,

how-to-use-retinoidsAs a certified dermatologist, I am often asked by patients if there are any creams to prevent and treat wrinkles. Luckily, there is! Retinols are vitamin A based derivative that increase cell turnover and help build collagen. Retinols are also great for treating blackheads/whiteheads and help reduce the appearance of some sun spots by exfoliating them away. Until three months ago, prescription strength retinols could only be prescribed by an MD, however Differin recently became a great OTC alternative. Differin, also known as Adaplene .1% gel, is available over the counter at retailers like Target, Walmart, Walgreens, etc and costs approximately $15 for a 15 gram tube.

Retinols are available in varying strength from low to strong potency. Adaplene is considered a low potency option and is great for people with sensitive skin. However, some individuals may need a stronger retinol such as Retin-A (also known as Tretinoin which is a mid potency medication) or Tazorac (the strongest available retinol). It is best to consult your dermatologist before using any of these medications to determine they are safe for you to use.

 

Even though adaplene is considered a low potency retinol, it is important to be educated before using it.

 

All topical medications should first be patch tested on a small area of skin to see how you react to them. For many people, adaplene is a strong retinol and they experience peeling, redness and irritation with overuse. It is best to start using a retinol only a few times a week. When applying a retinol, you should always follow it with a moisturizer to prevent excessive peeling or irritation or even apply moisturizer before and after the retinol, sandwiching it in between to layers of moisturizer. It is best to use a moisturizer that is noncomedogonic product, like Cetaphil or CeraVe, that won’t clog your pores. For people who don’t want the added step of applying moisturizer, the  Tareen Dermatology Retinol Repair 50 is a great option which has moisturizer added to its formulation.

Retinol-Repair-50

It usually takes two weeks for your skin to get used to a retinol and over several weeks you may be able to increase your usage to every other night or nightly. Retinols are safe to apply long term by all ages but should be discontinued when planning pregnancy.

Summer Sun Protection

Categories: BLOG, Dermatological Conditions, Health, Skin Cancer, Tips and Tricks - Tags: , , , , , , , ,

fox9-new-melanoma-increase-dr-tareen-skin-cancerMemorial Day is right around the corner – that means BBQs, swimming and days on the lake will be here before we know it!  There’s no need to compromise your fun or limit outdoor activities, as long as you know how to safely protect your skin while enjoying the Minnesota summer!

The way we look at it, there are two strategies for sun protection (we recommend combining both!)  The first is true sun avoidance; this is wearing a wide-brimmed hat to shade your face and neck, wearing sun protective clothing (more on this below!) and pulling the big umbrella over to cover your picnic table. The second strategy for sun protection is sunscreen.  There are endless options available, so it’s important to know what you should be looking for when buying a sunscreen!

The American Academy of Dermatology recommends using a sunscreen that is labeled ‘Broad-spectrum’

Tareen Dermatology SilkShade Tinted Sunscreen Dermatology Roseville Twin Cities Minnesota Zinc

SilkShade Broad Spectrum Tinted Sunscreen with SPF 30 is a great natural source of topical Zinc.

(meaning that it protects against both UVA and UVB rays – both of which can lead to skin cancer AND the features of aging skin.)  You should choose a broad-spectrum sunscreen that is SPF 30 or higher and labeled as ‘Water Resistant.’  One interesting sunscreen tidbit is that you’ll no longer see ‘waterproof’ on sunscreens – no sunscreen is 100% waterproof and finally the labeling has caught up with this fact!  We recommend applying sunscreen 15 minutes before heading outside and reapplying every 2 hours (more frequently if swimming or sweating!)  

How much sunscreen do you need?  The truth is that less than 50% of people apply enough sunscreen to get the advertised SPF benefit.  For most people, 1 ounce (enough to fill a shot glass) is the amount of sunscreen needed to cover the sun-exposed areas of the body.  Don’t forget – you even need sunscreen when it’s cloudy (the UV rays still can get to your skin!)

What about the kids?  It is imperative that children use sunscreen regularly.  Children over 6 months of age should have a physical sunscreen of SPF 30 or higher applied every 2 hours.  Physical sunscreens use zinc oxide or titanium dioxide to actually physically block the UV rays.  These can be purchased in creams, sprays, sticks, even brightly colored formulations that your kids will love.

The sun protective clothing mentioned above is PERFECT for the little kiddos.  Instead of fighting to reapply sunscreen every 2 hours, throw on a sun protective rash guard while swimming and they won’t have to worry about creams or sprays to that area while they’re having fun.  Previously difficult to find, these sun protective clothing items can easily be found in most children’s stores – adults can find fashionable sun protective clothing for themselves at many clothing stores, as well as outdoor and sporting stores.  

Tareen Dermatology wishes you a safe, fun, and sun-protected start to your summer!  Happy Memorial Day!

Genetic Testing for Melanoma

With the increase in melanoma seen across the world, dermatologists are looking for genetic tests to better identify those at risk for melanomas and other aggressive internal cancers.

According to Dr. Sandy Leachman, M.D., Ph.D., chair of Dermatology at Oregon Health and Sciences University in Portland “Identifying the individuals who carry a causal melanoma mutation allows these patients to be screened for other cancers, like ocular melanoma or pancreatic cancer, before those cancers develop.  It is important to catch these cancers at their earliest stages, before they become life-threatening.”

Genetic testing is advantageous for melanoma patients as it allows targeted screening and early detection activities. For example:
-Mutation for p16 (cyclin-dependent kinase inhibitor 2A) — patients with this mutation carry a 70% lifetime risk of developing melanoma and a 20% lifetime of developing pancreatic cancer.
-Mutation of the BAB1 gene increases the risk for ocular melanoma and mesothelioma (not pancreatic cancer).

 

Patients who are recommended to have genetic testing for melanoma are those that meet the “Rules of Three”
  1.  At least 3 invasive melanomas in blood relatives OR
  2.  At least 3 melanomas in a single individual OR
  3. 3 melanomas in a patient/ family member as well as pancreatic cancer/other high risk cancers within a family(defined as astrocytoma, breast, prostate, ovarian, colon)
The Rule of 3 is just a guideline- if there is melanoma in an individual + a strong family history, please let Dr. Tareen and her colleagues know as we will help navigate the complexities of genetic testing.
The gene panel that is recommended to be checked in these individuals is the melanoma panel of CDKN2A, BAP1, CDK4, MITF, and POT. If the patient meets the “Rules of Three” for melanoma, as well as other cancers then an organ specific panel for breast, colon, ovarian, pancreatic or prostate cancer should also be obtained.
Genetic counselors can order these test. They are incredibly specific and may help save lives. If you or your family members meet any of these melanoma criterion, please let us know and we would be happy to discuss with you at one of our Tareen Dermatology locations in Roseville and Faribault,  Minnesota. We will help facilitate the advanced genetic testing necessary for early detection that may impact not only you, but also your family members.

All About Sunscreen

There are so many options when it comes to picking a sunscreen. You should always be looking for a broad spectrum 30+ SPF.

There are so many options when it comes to picking a sunscreen. You should always be looking for a broad spectrum 30+ SPF.

With our recent beautiful Minnesota weather and summer quickly approaching, we would like to take time to review with our patients the benefits of regular sunscreen use. It is important for everyone to use a daily sunscreen, regardless of your skin color or race. Regular sunscreen use can help prevent skin cancer by protecting you from the sun’s harmful ultraviolet rays. According to the American Academy of Dermatology, it is estimated that one in five Americans will develop skin cancer in their lifetime

So what type of sunscreen should I use?

Tareen Dermatology SilkShade Tinted Sunscreen Dermatology Roseville Twin Cities Minnesota Zinc

SilkShade Broad Spectrum Tinted Sunscreen with SPF 30 is a great natural source of topical Zinc.

  • We recommend a “broad spectrum” sunscreen, which means that it will protect your skin from both UVA and UVB rays. UVA rays penetrate deep into the skin’s thickest layer, and unprotected exposure can lead to premature skin aging, wrinkling, and suppression of the immune system. UVB rays burn the superficial layers of your skin and it plays a key role in the development of skin cancer.
  • Choose a Sun Protective Factor (SPF) of 30 or higher. While no sunscreen blocks 100 percent of the harmful UV rays, SPF 30 blocks 97%, SPF 50 blocks 98%, and SPF 100 blocks 99%. It is also important to remember that high-number SPFs last the same amount of time as low-number SPFs.
  • Look for water resistant products. There is no sunscreen that is completely water proof. Sunscreen manufacturers can use the term “water resistant” if the sunscreen has been proven to remain effective in water for a period of time, usually 40 or 80 minutes. It is important to reapply sunscreen after swimming.
  • We recommend mineral based products that create a physical barrier on the skin. Look for sunscreens containing the ingredients zinc oxide or titanium dioxide. The physical blocking sunscreen offers immediate protection from the sun, as opposed to the chemical based sunscreens that must be absorbed into the skin for 30 minutes prior to going outdoors.
  • A few brands that we like include Elta MD, Tareen Dermatology SilkShade, Vanicream, CeraVe, and Blue Lizard.

When does my sunscreen expire?

We recommend using sunscreen every day when you are outside, even during the winter and on cloudy days, as the sun emits harmful UV rays year-round. If you are using the correct amount of sunscreen every day, a bottle should not last long. That being said, the FDA requires that all sunscreens retain their original strength for at least 3 years. Some sunscreens will have an expiration date, throw it out once the date has passed. Look for visible signs that the sunscreen is no longer good, including obvious changes to color or consistency.

How much do I need to use?

Most adults need one ounce of sunscreen to fully cover the sun exposed skin. This equates to the amount you could hold in the palm of your hand. Most sunscreen bottles are 3 oz in size, so if using the correct amount, a bottle should only last for about 3 applications. Remember your neck, face, ears, tops of feet, and scalp if you have thinning hair. Don’t forget about your lips- apply a lip balm with SPF at least 15. Left sided skin cancer is more prevalent due to the sun exposure related to driving. Be sure to take extra precautions to protect your skin while driving.

What should I do if I get a sunburn?

We hope that you can avoid getting a sunburn in the first place by wearing proper protection, but in the event of a sunburn, the first thing you should do is get out of the sun and get indoors. Treating the sunburn as soon as you notice it will help to heal damaged skin more quickly. Here are some tips and tricks to soothe and heal the irritated skin:

  • Take frequent cool baths or showers to help relieve the pain. Apply a thick moisturizer to damp skin after showering to seal water into your skin. Using a moisturizer containing aloe vera or soy can help soothe inflamed skin.
  • You can apply a small amount of over-the-counter 1% hydrocortisone cream to areas that are particularly uncomfortable. Avoid applying “caine” products (like benzocaine), as these can further irritate the skin and cause an allergic reaction
  • Nonsteroidal anti-inflammatories (NSAIDs) like ibuprofen can help reducing swelling and discomfort associated with the burn.
  • Drinking extra water when you are sunburned helps prevent dehydration.
  • If your skin blisters, allow the blisters to heal while taking extra care to protect the sun burned skin. Avoid popping the blister, because the reason it forms is to help heal your skin and protect you from infection. If you develop blistering of the skin, it means that you have a second-degree sunburn.

Melanoma Monday

Categories: BLOG, Dermatological Conditions, Health, Skin Cancer - Tags: , , , , , ,

Today is Melanoma Monday!

moles-atypicalThis is an important day for all of us at Tareen Dermatology, as it gives us the opportunity to remind our patients that although melanoma is one of the deadliest forms of skin cancer, it can be prevented with good sun protection and easily treated when caught early. We recommend that all of our patients have what we refer to as a ‘full body skin exam’ once a year, so that we can monitor your skin for new or changing moles. If you have had a skin cancer previously, we may even recommend that you come in more frequently. During this visual exam, we identify lesions or moles on your skin that should be monitored or removed for evaluation.

So why is it so important to be monitored for melanoma (and other skin cancers)?

The reason we recommend the once year skin exam is because melanoma can be treated successfully if diagnosed early. The American Cancer Society estimates that there will be over 87,000 new cases of melanoma diagnosed in 2017 alone. Although melanoma is not the most common type of skin cancer, it is the most common cause of death from skin cancer. It is estimated that nearly 10,000 people will die of melanoma in 2017, that’s approximately one person every hour.

Malignant melanoma evolving from a preexisting mole

We don’t share these facts and statistics from the American Cancer Society to scare you; we share them with you to remind you of the importance of regular dermatology visits to screen for melanoma and other skin cancers. Your risk of melanoma can increase due to factors like genetics, history of multiple sunburns and tanning bed use; however, a recent study by The Journal of Clinical Oncology reported that the daily use of sunscreen can reduce your risk of developing melanoma by 50 percent!

What can you do at home to monitor your skin for melanoma?

Great question! Performing self-checks at home is an important way to catch a new or changing mole. If you notice something new or changing, we recommend scheduling an appointment for evaluation with one of our Tareen Dermatology providers right away.

Here is what we recommend you look for when checking your skin at home – we call this the ABCDEs of Melanoma:

ABCDE of Skin Cancer

ABCDE of Skin Cancer

A – Asymmetry

B – Border Irregularity

C – Color Variation

D – Diameter greater than 6mm

E – Evolving (does that mole look different than it did last year?)

On this Melanoma Monday, please remember to schedule your yearly skin exam at Tareen Dermatology and make a pledge to practice safe sun habits to protect yourself and your loved ones in 2017.

Laser Tattoo Removal-What you need to know

Categories: BLOG, Cosmetic, Tips and Tricks - Tags: , , , , , , ,

Tareen Dermatology is proud to offer the first Enlighten™ laser in enlightenMinnesota for laser tattoo removal.

Enlighten features extremely short and high-power picosecond laser pulses which breaks down the ink particles that make up tattoos. A ‘picosecond’ is one-trillionth of second, and is 1,000 times shorter than the ‘nanosecond’ pulses used in existing laser treatments for tattoo removal. Picosecond laser pulses have been shown to remove tattoos more completely and require 40% fewer treatment sessions than traditional lasers. The Enlighten laser also uses two wavelengths, one long and one short, to treat a variety of ink colors, even red ink. The Enlighten laser is a safe and effective treatment option for all skin types.

Laser tattoo removal often requires multiple treatments depending on the composition, depth, color and size of the tattoo. Tattoo ink is deposited deep in the skin and in order to reach all of the ink in the skin, multiple treatment sessions are needed for clearance.

Screen-Shot-2016-01-01-at-9.36.09-AM

Patients are always worried if laser tattoo removal hurts. Most people compare the procedure to a rubber band being snapped against their skin. At Tareen Dermatology, we use topical or local anesthetics to minimize discomfort.

It is common for patients to experience redness and swelling immediately following the treatment. These side effects are temporary and most patients can return to regular activities immediately following the treatment.

Price varies by size and the intricacy of the tattoo. Free consultations are offered prior to treatment. Contact our office at 651-633-6883 or appointments@tareendermatology.com for more information and to schedule your appointment.

The Redness Bias: Does facial redness influence perceptions of people?  

Categories: BLOG, Cosmetic, Dermatological Conditions, Health, Tips and Tricks - Tags: , , , , , , ,
Facial redness, flushing, and bumps — also known as rosacea — is a very common problem.  It occurs in up to 10% of Caucasian individuals.  For those who experience redness it can not only impact them socially and emotionally but will often affect other people’s perceptions of them.

 

A recent study conducted by Dr Linda Papadopoulos in London demonstrated that among 6,831 individuals, photos of people who suffered from facial redness were rated to have poorer health and negative personality traits. Those same individuals, when shown with clear faces, were perceived as “well” and “healthy.”  Furthermore, participants were more likely to be friends with or hire the person shown in the image WITHOUT facial redness.

For the individuals who suffered from redness, 77% reported an emotional impact. They reported that other individuals have told them they drink too much or to recommend skin care interventions. However, these individuals reported much more control over their redness and symptoms once they were diagnosed. Once diagnosed with rosacea, 90% felt motivated to deal with their redness.

 

Dermatologists have a responsibility to help our patients deal with both the medical and psychologic impact of rosacea. At Tareen Dermatology in Roseville, Minnesota we specialize in medical, laser, and lifestyle interventions for rosacea and facial redness.

 

Children’s Eczema: How to prevent this uncomfortable condition

Categories: BLOG, Cosmetic, Dermatological Conditions, Health, Tips and Tricks - Tags: , , , , , , , , , ,

infant-eczemaEczema –a skin disorder characterized by rough, red, scaly and itchy skin — is on the rise. It is estimated that up to 20% of children in the United States suffer from varying forms of this disorder.

Recent research has given new strategies to help prevent this uncomfortable skin disorder.
1. Daily application of emollients from birth: Applying moisturizer from birth has been shown to significantly reduce the development of eczema. The benefit is due to enhancement of the skin barrier.  Researchers propose that daily application of moisturizer to all babies constitutes an effective, safe and cheap strategy to help prevent eczema.
2. Home water softeners: A study in England determined in children genetically prone to eczema, that hard water exacerbated the condition. Further studies are underway.
3. Probiotics: Maternal consumption of probiotics, especially during the third trimester, may reduce the development of eczema. The science shows that probiotics increase the development of diverse gut microbes. These microbes have a protective strategy against eczema.
Simple and effective strategies for eczema are easy to incorporate into our daily lives and can help protect the next generation against this itchy and uncomfortable skin disorder.
