keratosis
"I am on day 14 of using Carac. My face is extremely red, tight, itchy and a little sore, but I've had serious eczema in the past and this isn't nearly as bad as that was. It took about a week to show up on my forehead but then a couple more days they started intensifying on my cheeks, chin and sides of my face.  It is a little unsightly but once I explained to people what was going on and that it wasn't permanent or contagious they seemed to relax.  I tried Vaseline for moisturizing but that seems too greasy.  Products with zinc oxide in them seem to give me relief and protect me from the sun as well.  Please do not spend ANY time in the sun when using this.  The doctor told me it could permanently make your skin darker in those areas!"
