Hello, I can understand your concern for the dime size blemishes on face. After analyzing the query I can obtain that your daughter can have a possibility of “Fixed drug eruption”. It requires either a close picture or a close examination of the area to diagnosis the exact entity. As you have given a history of drug problem in your daughter so the possibility of “Fixed drug eruption” is on higher side. I suggest you to observe the area for few days of period and if it increases then should consult a dermatologist. In my patients with your kind of condition I generally suggest to do keep the area away from direct sunlight. I also prescribe a mild steroid based cream such as cortisone cream for local application. You can take further guidance from a dermatologist. All the best.
