I started to use Clindoxyl about a week ago and my skin became very dry so today I started to use some moisturizer. However, yesterday I noticed that somekind of blain was coming to my chin and I was right. Now it's a bit reddish and its diameter is about 1 cm (0,4 inch) but my skin is still undamaged in that area.

I iced it three times today and put clindoxyl on it and took some ibuprofen tablets. I don't know if it's right procedure but what I could do that it wouldn't cause any damage to my skin? Moreover, Is it ok to use clindoxyl which contains benzoyl peroxide instead of antibiotic cream?

EDIT: Now its head is starting to look a bit white and its diameter isn't so big anymore. What to do?

Keep icing, etc. Last resort: cortisone shot.

Now this blain is divided into two smaller red pimples which are, however, under the skin. In addition, there isn't the small white head anymore as it left when I washed my face. So, should I still use antibiotic cream and keep icing it or should I use bp from now on?
