Study Summary

The purpose of this study is to assess the comparative efficacy of retinol 1.0% and tretinoin 0.02% in minimizing wrinkles, discoloration, roughness, and other signs of moderate to severe photodamage. Our hypothesis is that both products will be of comparable benefit.

Primary Outcome

A photonumeric scale for the assessment of cutaneous photodamage (CE Griffiths, et al). Five photographic standards (en face and 45 degrees oblique) illustrating increasing severity of photodamage (min=0, max=8) where 0=no damamge; 2=mild damage; 4=moderate damage; 6=moderate/severe damage; and grade 8=severe damage.
