actinic keratosis
"Used it for 4 days and no results whatsoever. Typical 5%  Fluorouracil Cremes show at least redness. Tolak has shown none. More so, the formulation of it is horrible in that there are little white clumps Right out of the tube that make application difficult. The manufacturer offers hugely discounted coupons. You're better off buying the generic for better results."
