I have recently gotten a new acne medication. I used to used Tretinoin 0.5 it was working but it didn't give me the results I wanted since I was using it for half a year and it only improved a tiny tiny bit. The new medication I got was Tretinoin 0.1, which is a stronger version. The first night I used it (last night), it burned a tiny patch of skin off my face! The photo is a little blurry, but I know for sure this isn't acne. Help!
