question: Hi doctor, I used to take treatments for facial hair removal using a laser, microdermabrasion, and chemical peeling. I did these treatments before two years. My skin has become worse now. I have more dead cells in my skin, and I have darker looking skin. Even my lips have turned dark. My entire upper lip is black. I do not know the reason behind this problem. Do I have this problem due to the laser treatment or due to hormonal imbalance? I am taking medication for thyroid, which is normal now. I am taking Metformin for hormone regulation. I have facial hairs, and it grows faster. I have facial hair above the lips and chin. I use a razor to clear it. Please prescribe me ointments or creams to reduce the problem.
