A new study shows that daily sunscreen use may visibly reverse the signsof existing photodamage, in addition to preventing additional sun damage. In the study conducted at Memorial Sloan-Kettering Cancer Center and published by the American Society for Dermatologic Surgery, patients used a broad-spectrum photostable sunscreen* over the entire face for 52 weeks. Results measured at week 12 showed visible improvement in several areas, with continued improvement through week 52. Skin texture, clarity, and mottled and discrete pigmentation were the most improved parameters by the end of the study (40% to 52% improvement from baseline), with 100% of subjects showing improvement in skin clarity and texture.
This study supports our recommendations for applying a facial moisturizer or makeup with SPF every day even if you do not expect to be out in the sun for extended periods. You can view the entire publication here.
*The test formulation was a broad spectrum, photostable sunscreen with SPF 30. The composition of active ingredients in the SPF formulation was Avobenzone (3%), Homosalate (12%), Octisalate (5%), Octocrylene (1.7%), and Oxybenzone (3%).
