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

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’

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!

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.

Sunscreen Recommendations

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.

The Spring Break season is upon us and as a board certified dermatologist I am often asked by my patients about what to look for when choosing a sunscreen.

When looking for a sunscreen I always recommend a mineral based product that will create a physical barrier on the skin, particularly sunscreens that contain zinc oxide or titanium dioxide. In contrast, the chemical based sunscreens (long names include avobenzone, octocrylene, ecamsule, etc.) must be absorbed into the skin to provide sun protection. Also good to know – the mineral sunscreens provide almost immediate protection while chemical sunscreens need to be applied approximately 30 minutes prior to going outside in order to be effective.

Zinc is the only ingredient that I use for my children’s sunscreen. In fact, the FDA recommends zinc as the main sunscreen ingredient for babies.

Zinc alone can be very chalky and white so it is important to look for the words “micronized.” This is a process whereby the mineral particles are made finer and more cosmetically elegant (but does not decrease the sunscreen efficacy).

A few brands that I like: Elta MD sunscreen, Vanicream sunscreen (made in Minnesota!), CeraVe AM, and of course the Tareen Dermatology SilkShade.

A few other good tips to keep your skin safe while enjoying the beautiful weather:

  • Look for broad spectrum sunscreen with SPF 30 or higher
  • Sun protective clothing and wide brimmed hats can be stylish and comfortable
  • Do not “lay out” to get a base tan: this only provides an SPF of 4 and falsely makes one think they are protected
  • UV blocking sunglasses and lip balm are imperative (ocular melanoma and lip cancers are on the rise!)
  • Remember, there are statistically more skin cancers on the left side of the face and body due to chronic sun exposure from driving- use extra protection on the left side and think about investing in UV tinted windows
  • Examine your skin head to toe once a month and see your dermatologist yearly for a skin exam

As a board certified dermatologist, I can assure my patients that NOT using sunscreen increases the risk of sun damage and skin cancer.

The key ingredient you should look for in sunscreen is ?

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.

Sunscreen and its ingredients are a controversial and personal topic. The media inundates us with mixed messages – at one end berating individuals for not frequently re-applying and on the other end claiming that sunscreen and its ingredients actually CAUSE cancer.

I always strive to be the voice of reason for my Minnesota patients. As a board certified dermatologist, I can assure my patients that NOT using sunscreen increases the risk of skin cancer. However, I agree that constant use of many chemicals MAY (and I stress may) be harmful.

Thus, the key ingredients that I stress for my patients are minerals, particularly zinc oxide. These mineral based sunscreens (which typically contain zinc oxide or titanium dioxide) sit on top of the skin as a shield and protectant from the sun. In contrast, the chemical based sunscreens (long names include avobenzone, octocrylene, ecamsule, etc.) must be absorbed into the skin to provide sun protection. Also good to know – the mineral sunscreens provide almost immediate protection while chemical sunscreens need to be applied approximately 30 minutes prior to going outside in order to be effective.

Zinc is the only ingredient that I use for my children’s sunscreen. In fact, the FDA recommends zinc as the main sunscreen ingredient for babies.

Zinc alone can be very chalky and white so it is important to look for the words “micronized.” This is a process whereby the mineral particles are made finer and more cosmetically elegant (but does not decrease the sunscreen efficacy).

A few brands that I like: Elta MD sunscreen, Vanicream sunscreen (made in Minnesota!), CeraVe AM, and of course the Tareen Dermatology SilkShade.

I hope this sheds light on a confusing topic and encourages more of my patients and friends to safely protect their skin with my favorite ingredient zinc!

 

Vitiligo: Causes and Treatment

Categories: BLOG, Cosmetic, Dermatological Conditions - Tags: , , , , , , , , , ,
Tareen Dermatology patients before and after completing treatment

Actual Tareen Dermatology patients treated with excimer laser for vitiligo

 Vitiligo is an auto-immune disorder which causes white, de-pigmented patches to appear on the skin. 

Although it is unknown why the immune system attacks the pigment cells, we now have excellent treatments to help achieve re-pigmentation of the skin.

One of the most exciting advances in the treatment of vitiligo is the excimer laser. The excimer laser utilizes an anti-inflammatory, focused wavelength of light to target inflammation in the skin and stimulate re-pigmentation. 

Phototherapy, which utilizes safe narrowband UVB, is another successful treatment modality for widespread vitiligo. These quick and painless treatments utilize a full body light source to target inflammation and bring back the skin’s natural color.

There are many benefits to the excimer laser and phototherapy treatments for vitiligo including:

-Safety: These anti-inflammatory wavelengths of light only target the skin. There is no systemic absorption, thus treatments are safe for almost all ages and individuals.
-Efficacy: Treatments bring back pigmentation (either completely or at least partially) in over 80% of individuals.
-Cost: Insurance covers the cost of most treatments (including Medicare).

Tareen Dermatology in Roseville, Minnesota is proud to offer these safe and effective laser and light treatments for vitiligo. Individuals with these white patches do not need to suffer anymore – Tareen Dermatology is happy to help! Dr. Mohiba Tareen will be on ABC’s Twin Cities Live, channel 5, discussing vitiligo treatments on Monday, August 1st at 3 pm or contact our office for more information.

A Probiotic A Day To Keep the Dermatologist Away?

Probiotics – helpful bacteria that protect the body from harmful bacteria – are everywhere in the media these days. In addition to yogurt, other sources of probiotics include kimchi and the tea beverage kombucha.  For skin health, several studies have shown that probiotics may be beneficial for acne/rosacea, eczema, infections, and even anti-aging.

Acne/Rosacea:

Probiotics have been shown to reduce inflammation (by preventing the body’s immune response to surface bacteria), thus reducing redness and lesion counts in these conditions.

Eczema:

Probiotics may help reduce the number of infections, particularly with MRSA (a harmful bacteria that lives on the skin) in people with eczema. Probiotics may also help increase the health of the skin barrier and reduce inflammation.

Chronic Wounds:

Studies are underway utilizing topical probiotics to help heal wounds. One study currently shows that a probiotic based gel is more effective than the current standard of care silver based dressing.

Anti-aging:

Ingestion of probiotics may help protect the skin against sun damage. A study found that mice supplemented with probiotics three times a week experienced less UV damage, and more hydrated skin than those who were not supplemented. Furthermore, the mice that were supplemented had more thick and lustrous fur.

For all of these conditions, the optimal doses of probiotics have not been defined. At our Minneapolis dermatology clinic, I counsel my patients: “A probiotic a day may help keep the dermatologist away!”

  1. Sunscreen is your friend: It is estimated that 90% of aging and skin cancers are related to ultraviolet light. A broad spectrum sunscreen that protects against both UVA and UVB rays will keep your skin safe and young!
  1. Sometimes more is not necessarily better: The American Academy of Dermatology recommends SPF 30 and above. SPF 15 protects against 93% of the sun’s rays, while SPF 30 protects against 97%, SPF 50 blocks 98% and SPF 100 blocks 99%. Thus, some dermatologists advocate that any sunscreen over 30 just gives users a false sense of security. More important than the number on the bottle is frequent re-application (every 2-4 hours), particularly after swimming or sweating.
  1. Use Sun Smarts: It is not just about sunscreen- the judicious use of sunglasses, wide-brimmed hats, and sun protective clothing is equally as important as sunscreen. For my own children, I like rash guards and clothing that physically limits ultraviolet light on the skin. Two great affordable websites include www.coolibar.com and www.swimoutlet.com.
  1. Use an anti-oxidant: Topical anti-oxidants include vitamin C and ferrulic acid. These ingredients help neutralize free radicals -toxic compounds generated by sun and pollution. They provide an extra layer of protection from the sun and brighten the skin!
