You asked, and Dr. Dina D. Strachan, MD has answered. This board-certified dermatologist is a graduate of Harvard and Yale and currently holds a faculty appointment at NYU.  We recently asked readers to submit their skincare questions for Dr. Strachan. Check out her responses to questions about acne, dark spots and under eye circles.

1) I have been recently having issue’s with acne? This is new for me because my skin is normally clear. What can I do to prevent his from happening and remove the dark spots the bumps are leaving on my face?

Acne vulgaris is a common skin disease that often affects a person for the first time in adulthood. Genetic and hormonal factors are the primary causes. There is also some evidence to suggest that stress and a high-glycemic diet may also be triggers. In people with dark skin, acne lesions may leave behind brown spots that take many months to heal. Severe acne can also result in true scarring with depressed and raised lesions on the skin. There are different types of acne lesions and a number of precription medications and treatments. The best thing to do if you suffer from acne is to get evaluated by a board-certified dermatologist who can pick the best treatments and procedures for you.

2) I’m starting a natural treatment of apple cider vinegar on my skin for hyperpigmentation. Doest that really work?

There appears to be a lot of buzz about this as an effective home remedy for hyperpigmentation. I am unaware of any studies. It certainly might work. It probably results in some mild exfoliation which removes excess pigment.

3) Are there internal remedies for undereye circles -something to help stop the leaky capillaries?

I am unaware of any internal remedies for undereye circles. These circles can be challenging to treat as they have a variety of causes. Some people have truly darker skin under their eyes. This may be genetic or the result of rubbing the eyes from allergies. Some people have thin skin, or thinning of the eyelid skin as a results of aging, with increased visibilty of the blood vessels. We also lose volume in our cheeks and around our eyes and have hollowing of the body part of the eye sockets resulting in shadows. These are the reasons why it’s hard to find an treatment for this problem that works for everyone.
