Background: Photoaging due to cumulative lifetime ultraviolet light exposure is the greatest contributing factor to facial aging. With the continued growth of the population of individuals aged ≥65 years and over, demand for safe and effective photoaging treatments will likely increase.
Methods: This qualitative review provides an overview of efficacy and safety of over-the-counter (OTC) and prescription topical treatments for photoaging, including recent data from an investigator-initiated trial of the topical retinoid tazarotene.
Results: OTC and cosmeceutical products comprise the majority of treatment options for photoaging, although clinical data in support of their efficacy are generally lacking. Topical retinoids have been shown to increase collagen and elastic fibers and normalize melanocytes and keratinocytes, yielding improvements in wrinkling, texture, elasticity, and skin tone. Prescription topical retinoids (adapalene, tazarotene, tretinoin) are the most studied and efficacious treatments for photoaging, though their use is typically associated with adverse effects such as erythema, peeling, dryness, and burning/stinging in a concentration-dependent manner. In a 12-week, open-label study, lower-dose tazarotene 0.045% lotion led to significantly reduced signs and severity of photoaging vs baseline.
Conclusion: Prescription topical retinoids are the most potent treatment option for photoaging, though their use may be limited by irritation concerns. Tazarotene 0.045% polymeric emulsion lotion has recently demonstrated significant photoaging improvements with 12 weeks of once-daily treatment, with a favorable safety and tolerability profile.
