Fragrance-Free and Hypoallergenic Moisturizers: MOST are not!

A study published in JAMA looked at the 100 “best-selling” moisturizes that claim to be “hypoallergenic” found that 83% had a potentially allergenic chemical. Additionally, the study found that 45% of the products marketed as “fragrance-free” contained a botanical ingredient or one that reacts to a fragrance that can cause reactions.

Consuming alcohol increases risk of Skin Cancer: maybe

A recent study has shown a positive association of increased alcohol consumption with the risk of non-melanoma skin cancer. The study was small, so larger studies are needed to confirm these preliminary results.

Here is yet another possible reason to limit or eliminate alcohol consumption. Red wine has some other health benefits that, according to some, might outweigh the negative effects when taken in moderation–no more than one glass per day, but even that is somewhat controversial.

Erectile dysfunction treatments lead to increased risk of melanoma and basal cell carcinoma.

The use of PDE5 inhibitors such as sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) are common for those with erectile dysfunction. More and more research has shown an increased risk of some types of skin cancer for those taking these medications. Interestingly, there have been no studies showing an increased risk of squamous cell carcinoma.

For this reason, those with a history of melanoma should take this into consideration when considering taking one of these medications. Those with a personal history of multiple dysplastic moles or family history of melanoma should also take this into consideration. For patients whom have had multiple basal cell carcinomas should also weigh the risks of taking these medications.

How to store pain medications

Now I know that this post has nothing to do with skin care, but it is in the best interest of public safety.

It is not uncommon for one to receive a prescription for narcotic pain medication after having a procedure. In fact, often, one does not finish all of the medication. But, what does one do with them?

Prescription narcotics is one of the biggest when it comes to drug abuse, especially among teens. It is essential to keep narcotics in a secure, locked location. Often one does not finish them and leaves the bottle in an unsecured location for many months or years. This is not recommended.

Even if your kids are all grown and out of the house, do you have grandchildren or other teenagers or young adults visiting?

Be safe.

PRP: is it worth all the hype?

Celebreties are raving about it, doctors are promoting it for many things, but is it really worth the hype?

In short, PRP is not FDA approved for anu Dermatologic or Cosmetic indication. There are several small studies that concluded that there is benefit when treating androgenic alopecia. That being said, larger, well-designed studies are needed. For other indications, such as photo-rejuvenation, studies are even more poorly designed.

There is a good scientific basis for why PRP may help a variety of conditions. Unfortunately, due to a lack of good clinical studies further research is needed. So the answer to the question of whether is is worth the hype is maybe. 

Often, PRP is combined with another procedure–laser resurfacing+PRP, or Restylane+PRP. When doing so, it is difficult to know if the PRP is adding any benefit.

Diet & Acne: What to avoid

For decades, we have told patients that there were no studies to support that drinking soda made acne worse, although if that was their experience then they should not consume soda. Over the recent years, more and more evidence has emerged showing that diet can affect acne. The first study showed that drinking non-organic milk may exacerbate acne. Recently a study published in the The Journal of Academic Nurtition (J Acad Nutr Diet. 2017 Jun 9. doi: 10.1016/j.jand.2017.03.024 ) showed that consuming high-glycemic index carbohydrates is correlated with worsening of acne. 

In short, the recommendations have not changed–for all persons, eating a good healthy diet is recommended. What has changed is the evidence showing that poor eating habits is connected with worsening of acne. For all of my patients, acne or not, I recommend avoiding white rice, white potatoes, white flour, and sugar in their diet. Unfortunately, most of my patients, with or without acne, consume a large amount of these high-glycemic index foods, which contributes to obesity, fatigue, and the development of type II diabetes.
