I'm on week 9 of using tretinoin cream for acne. the dryness and pimples have basically stopped but in still red. when do all side effects stop?

Tretinoin is a long: term treatment that takes 3 to 6 months of regular use to see maximum benefit. To reduce dry red skin remember to use only a very small amount each time, use a light & mild moisturizer afterwards (Aveeno (oatmeal) ultra-calming, Neutrogena sensitive, etc), and AVOID the sun. If you follow these rules but still have redness after three more weeks, see your doctor again to re-evaluate your usage regiment.

Soon!: So glad that your skin is getting better. Your redness should start to go away this month. You can back treatment down to every other day, also. This might help.

Can try: decreasing to every other day to dwcxease the redness.
