DD is 18. She had quite bad skin about 18 months ago. I took her to the pharmacist who suggested Acnecide, which worked however recently she has began to find it less effective and it has began to make her skin peel with dryness (she's been using aveeno but it's still dry). Any suggestions on what to try next? She's also cut out lactose (about a year now) and has noticed a difference. Thanks
