Reader Question: I have small blemishes on my face that are causing uneven skintone. I always see products that help fade dark spots, but mine are reverse. I have light blemishes what can I do/use to even skintone?
Dr. Strachan: Whenever there is inflammation in brown skin, such as that caused by acne, rashes, scratches and burns there is a chance of a color change. Usually this results in skin darkening but occasionally inflammation leaves light marks. Whenever the skin is constantly blemishing it is important to determine the reason. In people with acne that leaves blemishes, for example, if they focus on the blemishes, which generally last much longer than pimples, rather than the acne problem, they will always have blemishes. In this case, it would be best to treat the acne if one wants to blemishes to go away. There are no specific products to address blemishes that are lighter than the normal skin color. The solution is to find out what is causing them. Is there an eczema or seborrheic dermatitis problem?
Reader Question: How can I shrink open pores?
Dr. Strachan:Pore size is genetic and generally does not change, unless the skin is damaged, in which case the pore might get bigger. All we can really do is try to minimize the appearance of our pores. The best way to do this is to keep the skin clean and exfoliate gently.
