Derm approved: Sunscreen dupes
Everybody knows that they are supposed to wear sunscreen every day to protect against the harmful UV rays from the sun that cause wrinkles and skin cancers.  But it is hard to know which ones work best.  There are so many on the market and they all claim to be the best or "dermatologist recommended”.    Over the years I have tried many and some definitely work better than others.  Every year Consumer Reports tested the top 100 or so sunscreens to see if their marketing is accurate.  You would be surprised by what they find.  Just because some sunscreens claim to be SPF 50, does not mean they actually are.   I am going to compare 2 sunscreens, which were both ranked at the top of Consumer Report’s list, La Roche Posay Melt In Sunscreen Milk SPF 60 and Equate Ultra Protection Lotion SPF 50.   La Roche Posay Melt In Sunscreen Milk SPF 60LA ROCHE-POSAY - Melt-in Sunscreen Milk SPF 60 Pro’s   1.     Dries quickly 2.     Not greasy 3.     Does not feel heavy on my skin 4.     Made for Sensitive skin 5.     No parabens (which can cause irritation or allergic reactions) 6.     Has anti-oxidants (which help get rid of free radicals from the sun which can cause damage to our collagen and subsequently lead to wrinkles) 7.     Great sunscreen protection   Con’s   1.     Pricey at $35 2.     Does not say if it is safe for acne   Equate Ultra Protection Lotion SPF 50equate - equate Ultra Protection Sunscreen SPF 50 Pro’s   1.     Does not feel heavy on my skin 2.     Dries quickly 3.     Priced well at $8 4.     Great sunscreen protection   Con’s   1.     Has parabens 2.     Feels greasier 3.     Does not say it is for sensitive skin 4.     Does not say it is safe for acne 5.     No anti-oxidants   Both sunscreens have great protection and I liked both of them.  I liked the feel of La Roche Posay better because I have oily skin.  Because I have sensitive skin, I liked the fact that La Roche Posay was made for sensitive skin and did not have parabens.  Since La Roche Posay is more expensive, I use it on my face and Equate on the rest of my body.

Derm Approved: How to Banish Enlarged Pores
Derm Approved: How to Banish Enlarged Pores
The pores on your skin are actually openings in the skin from which your hair grows out of.  Our hair follicles have oil glands attached to them.  These openings can get plugged with oily and debris from the skin/dead skin cells leading to enlargement of your pores.    Several factors play a role in causing enlarged pores.   1.     Genetics 2.     Non-comedogenic products 3.     Acne 4.     Loss of elasticity that results from the aging process 5.     Chronic sun damage   Enlarged pores are very difficult to treat.  Here are some products which can help. 1.     Retinoids 2.     Exfoliation 3.     Chemical peels 4.     IPL 5.     Wash face twice a day and never go to bed with makeup on your face. 6.     Use non-comedogenic products (cleansers, moisturizers, sunscreen, makeup) 7.     Always use sunscreen daily and re-apply every 2 hours because one application does not last all day.     I have found prescription retinoids to be most helpful.  Retinoids help get rid of dead skin cells and decrease oil production, both which lead to clogged pores.  They are also great at helping to rebuild collagen and elastin that decrease with age and sun damage, which leads to wrinkles.  I have used a prescription product called Tazorac (tazarotene) for many years and found it to be helpful.  It is from Allergan, the makers of Botox.  I originally started using Tazorac to treat my acne, but it also helped fade my dark spots, help with wrinkle treatment and prevention, and decrease my pore size.   You have to be careful with the use of retinoids.  If you start out using them too often and use too much, they can be very irritating.  Here are some guidelines.   1.      Do not use if you are pregnant or thinking about becoming pregnant or nursing 2.     You must use sunscreen daily and reapply every 2 hours.  Do not get direct sunlight on your face. 3.     Start out with a pea-size amount to cover your entire face. 4.     Begin using it twice a week for 2 weeks.  Then if your skin tolerates it, increase to 3 times a week for 2 weeks.  Then if your skin tolerates it, you can use it every night. 5.     Only use it once a day at night. 6.     Wait 30-60 minutes after washing your face before you apply it. 7.     You can apply moisturizer before or after using the retinoid. 8.     If you get redness, imitation, or excess peeling, stop using and call your doctor. 9.     People with sensitive skin may not be able to use retinoids.

Professionally, I Do Not Like St. Ives Apricot Scrub
Professionally, I Do Not Like St. Ives Apricot Scrub
I remember using St. Ives Apricot Scrub when I was a young teen because, at that time, it was a popular product.  More recently, St. Ives Apricot scrub has fallen out of favor because it allegedly cause micro-tears in the skin.  There was even a lawsuit against the parent company Unilever, which was eventually dismissed.   Scrubs are meant to exfoliate, or remove dead skin cells.  There are 2 different types of exfoliation, depending on the ingredients.  One is chemical and theater is physical.  Chemical exfoliators have a smoother texture and have less potential for damaging the skin. I find that there are more problems and more chance for overuse of products with physical beads rather than chemical ones.  St. Ives uses physical beads made of walnut shells.  If you must use a product with physical beads, stick to jojoba beads.   If you over use any exfoliator, you can cause problems with your skin.  It can lead to redness, inflammation, infection and tears in your skin.  Your skin will feel itchy, sore or burning.  Ultimately, continued over use could lead to scarring.  So it is important to only exfoliate 1-2 times a week and to use a gentle product that has a chemical exfoliator.    Patients with active rashes, active infections, cystic/inflammatory acne and skin cancers should avoid exfoliation.  If you have sensitive skin, you still may be able to use and exfoliator under your doctor’s supervision.  You should always consult with your dermatologist before beginning any regimen.

Derm approved: Get Smoother Skin With Dermaplaning!
Dermaplaning has recently become one of the most popular skin treatments.  It is basically a form of physical exfoliation, and similar to microdermabrasion.  It involves using a surgical scalpel to exfoliate dead skin cells.    Here are some benefits.   1.     Exfoliating dead skin cells 2.     Removes facial hairs without making them grow back thicker.  3.     Smoother skin and easier makeup application. 4.     It can be done monthly in addition to your regular exfoliation regimen.  5.     Help serums and moisturizers penetrate better and deeper since the outer layer is removed.  6.     Boost collagen production to help with wrinkles. 7.     Lighten dark spots 8.     Helps unclog pores   Dermaplaning should be done in a physician’s office by a trained medical professional.  If it is not done correctly, you can get an infection or permanent scars.  It should be a painless procedure with little to no downtime if it is done correctly.  Dermaplanig is also safe for all skin types.    After your derma planing procedure, make sure you use gentle products as your skin becomes sensitive afterwards.  Always use sunscreen to protect your skin after treatment since your outer protective layer is gone. Also, avoid direct sunlight on your face.   There are certain patients who should not get dermaplaning.  These include patients with active acne/cysts, active infection such as herpes, skin cancers, and active rashes.  Patients with sensitive skin may be able to get it done under a doctor’s supervision.

Derm Approved😍Essential Oil Guidance
Derm Approved😍Essential Oil Guidance
Essential oils are made from certain parts of plants, like leaves, and concentrated to produce oil.  There are few human trials done showing their effectiveness.  Some studies have shown their use in treating nausea or lowering stress, and as anti-microbial agents.  There is a lot of information out there on the internet, a lot of which is false and over promises results.  You must do your research and consult with professionals before starting a regimen.  You should not take their use lightly.  Many people have experienced severe rashes, breathing problems, allergic reactions, and even death from essential oil use.  Here are some “Do’s” when using essential oils: Make sure they are pure Dilute them as directed. Determine whether they are to be used topically or inhaled. Use appropriate dose Store safely. Try it out in a test spot first Here are some “Don’ts” when using essential oils: Avoid use on babies, young kids, and the elderly Do not use it if you have a skin condition, like eczema, or sensitive skin. Do not use it with certain medications, such as those for diabetes, depression, or anti-coagulation. Stop if you get skin irritation Avoid delicate areas, like groin Do not use if you are pregnant or nursing Avoid use of some oils with certain medical conditions, like epilepsy, high blood pressure, asthma, kidney problems, hypoglycemia, fever I personally do not use any essential oil on my skin because I have eczema and so many topicals irritate my skin.  I also have to be careful with inhaled oils as I have asthma.  I basically try to avoid them.  I did, however, try lavender oil for relaxation and sleep.  It smelled great but I found that it did not help me relax or sleep better.    I have patients who have found some success in treating their dandruff with tea tree oil.  It is supposed to decrease inflammation associated with dandruff and soothe the skin.  However, as with most essential oils, there is limited research supporting this claim.  Neutrogena and Head and Shoulder both make shampoos with tea tree oil.  But as with any oil, use caution because it can cause skin irritation and allergic reactions. Since essential oils can cause potential problems, you should consult with a licensed aromatherapist and your physician before beginning any regimen.  Always let all your doctors know what essential oils you are using since they can interact with certain medications and make certain medical conditions worse.

Derm Approved✨Back Acne Treatments🎉🎉
Derm Approved✨Back Acne Treatments🎉🎉
Back acne, or bacne, can sometimes be difficult to treat.   It also can be quite embarrassing for some people, especially teenagers.  It is similar to face acne, in that it is caused by excess oil production and dead skin cells that block the pores.  When bacteria gets trapped in the pores, the acne can be more inflamed and tender.   There are many reasons why people get back acne. Medications Hormones Stress Sweat and dirt Hygiene Genetics Here are some of the best over the counter (OTC) products to help treat back acne. Salicylic acid (SA) wash or spot treatment- My favorites are Neutrogena - Oil-Free Acne Wash and OXY - Acne Medication Deep Pore Cleansing Pads  SA is great at controlling oil production and getting rid of dead skin cells that clog our pores.  It is a mild product and a good starting place for mild acne or patients with sensitive skin. Benzoyl peroxide (BP) wash or spot treatment-   I like PanOxyl - Acne Creamy Wash Benzoyl Peroxide 4% Daily Control and Neutrogena - On-the-Spot Acne Treatment  BP is also great at getting rid of dead skin cells and controlling excess oil production.  It can a more irritating to your skin, so start off using it slowly.  It can also bleach your clothing, sheets and towels, so be careful. Retinoids - LA ROCHE-POSAY - Effaclar Adapalene Gel .01% Topical Retinoid Acne Treatmentand Differin Gel are the OTC products I like best.  These are great products for getting rid of dead skin cells and unclogging pores.  Retinoids can be irritating, so start out using it infrequently til you can build up to using it every night.  Retinoids are also great at fading the dark spot that acne leaves behind. Here are some tips to help alleviate back acne. 1.  Wear sweat-wicking clothes or loose fitting clothing 2.  Make sure backpacks or sports equipment doesn’t constantly rub against your back. 3.  Wash immediately after sports or working outside 4.  Use oil free, non-comedogenic products - that includes moisturizers, sunscreens, makeup 5.  Do not pick 6.  Eat a healthy diet low in carbs and dairy 7.  Clean your clothing after every use.  Clean your towels and bedsheets/pillowcases at least twice a week 8.  Keep your hair off your back 9.  If you cannot reach areas of your back to apply acne meds, use a lotion applicator. 10.  Clean sports or gym equipment before and after using it. If over the counter meds and these tips do not keep your acne under control, please seek help from a dermatologist to prevent permanent scars.
