OXY brand is the over the counter best used by people who can't afford to extend prescription dermatology treatments regularly. Oxy daily wash will not affect internal resistance to acne bacteria but it will evaporate the topical dermal landscape where applied. The bummer about this product is the release technology. It comes out in a soapy lotion that is easy to overapply. But only a very thin film is needed. You can leave even a diluted amount of this spread over your face and within minutes it will start to burn and will chafe if put on dry skin. It's good for acute treatment of bacne or other oily areas. After a few days of regular wash application, cut down. Only apply in trouble spots or patchy dry and irritated areas will arise. Sensitive skin will need to step off usage entirely between breakouts. Ten % benzoyl peroxide means this is as close to zapping acne as you can get. The size is deceptive, it's not like shampoo. You will learn to use a q tip dipped in the open top or get peroxide burn on your fingertips. Residue from wash can bleach clothing or hair. Double check hairline and neck and under chin for residues as well, this is strong stuff and can cause irritation is left on skin. But it will get rid of infections and acne redness lesions in shipshape fashion.
