Wait until these conditions have healed before using tretinoin topical.

Use this medication for as many days as it has been prescribed for you even if you think it is not working. It may take weeks or months of use before you notice improvement in your skin. If you are using tretinoin topical to treat acne, your condition may get slightly worse for a short time when you first start using the medication.
