Retinoid Therapy: Compatible Skin Care

Topically applied tretinoin (a retinoid) has been used for over 25 years to treat acne and disorders of keratinization. Now, tretinoin emollient cream, 0.05% (Renova^®), may be prescribed for the treatment of photodamaged and chronologically aged skin, in conjunction with appropriate skin care and sun protection routines. Mild to moderate cutaneous side effects to topical tretinoin, such as xerosis, peeling, erythema and subjective irritation, are experienced by a majority of patients undergoing retinoid therapy. Results of clinical compatibility testing show that concomitant use of effective moisturizers, mild cleansers and daily sunscreens greatly enhance skin tolerance and patient comfort. A frequently prescribed regimen for topical treatment of photodamaged skin includes a combination of tretinoin and glycolic acid. While many clinicians report the use of both these agents for the management of their patients, little information exists in the literature about their compatibility in concomitant use. The results of a double-blind clinical study demonstrate that daytime usage of one of two 8% glycolic acid lotions in addition to nightly applications of Renova was well tolerated as part of a comprehensive skin care and sun protection program.
