When considering procedures to get rid of wrinkles, brown spots, red spots, sagging skin, or loose skin, it is imperative to use the right topical products to protect your investment.
I tell my patients to think of the acronym GRASS to remember what classes of products are best to enhance and maintain whatever else they are doing at the dermatology office. Growth factors, Retinols, Anti-oxidants (like Vitamin C and E), Sunscreen, and Specialty products.
Some of the specialty products include those that help redness, bruising, hyperpigmentation, and skin laxity. We only carry products in our office that the health care providers and/or staff have tried themselves, so we have confidence in their efficacy and safety.
So many of my acne patients have it in their heads that they must moisturize their face daily. Acne is partly caused by overactive oil glands which leads to clogging of pores.
Moisturizing actually traps that oil under the skin, so it can potentially aggravate acne.
Use of moisturizer should be limited to days when the outer layers of skin are getting too dry, or to counteract the over-drying side effect of certain acne medications like benzoyl peroxide or retinoids. And even then, the moisturizer should be used very sparingly.
If the acne meds are causing too much dryness and irritation, then decreasing their use (for instance, once a week instead of daily) will still allow them to work but cause less side effects.
Many patients ask me if sunscreens can cause cancer. My answer is that there is much more evidence that sun exposure causes cancer than that sunscreen causes cancer. Read more at
In addition, I always use the example of Sweet and Low sugar substitute being declared to cause cancer.
If a study is done on mice and 1000 times as much of a chemical than can possibly be consumed by a person is given to those mice, you can't then conclude that the chemical will cause cancer in humans just because that huge amount of chemical caused cancer in the mice.
The American Academy of Dermatology still recommends sun protection via sunscreen and/or clothing. The higher the SPF the better, and re-apply every 2 hours, as the sunscreen eventually wears off.
Do we really need to go out in the sun in small doses in order to get Vitamin D?
As I live and work in Florida, I always tell my patients that they don't even have to think about it-- they're getting plenty of incidental sun exposure just by living in Florida.
Sun comes through the windshield of your car, through the windows of your house, and you get plenty of exposure just by walking the dog, walking from a parking lot to a building, or going out of the house to get the newspaper or mail.
There is no need to purposely not use sunscreen in order to get more Vitamin D. In this way, you are doing something bad in order to do something good. If you really are Vitamin D deficient, then it is much safer and more efficient to take Vitamin D supplements orally.
Everybody gets freaked out about bugs in the house. If you get bites on you skin and they blow up and look really bad, it is still much more likely they started as mosquito bites that you scratched really hard, rather than spider bites.
Other possibilities of bug bites are mites, midges, "noseeums," chiggers, and bed bugs. All of these are cured the same way-- find the bugs and get rid of them via a professional pest control service.
The only exception to this is the scabies mite, which is essentially the only bug that lives under your skin. This is why scabies has to be treated with a medicated pesticide cream that will kill the mites that are living on you and laying eggs.
