Class Summary
Although tretinoin has been used with some success, avoiding ultraviolet-induced pigmentation and an artificial coloration of the area is recommended as first-line therapy.
This drug is chosen perhaps because of its action in other actinic conditions.
Tretinoin topical (Avita, Retin-A)
Tretinoin has been shown to reverse some aspects of sun damage. It is available as 0.025%, 0.05%, and 0.1% creams and as 0.01% and 0.025% gels.
