The effect of retinoic acid cream to get rid of acne is still relatively definite, but there are certain indications, generally for early common acne, common acne with more pronounced whiteheads and mild blackheads and pimples are preferred to retinoic acid cream. This cream is usually applied topically after 1-2 weeks, and some people’s skin starts to show results, but this cream is used at night as much as possible, that is, try to avoid using it during the day. Because of its photosensitivity and light-absorbing properties, some people may experience local erythema and local itching after topical application of retinoic acid cream, so this side effect needs to be avoided as much as possible.
