Background: Data reflecting the impact of photoprotection on cutaneous aging are scarce and mostly limited to fair skin. Objective: To assess the effectiveness of a photoprotective product in counteracting the photoaging process in different skin phototypes over 1 year compared against a classical routine. Materials and Methods: Two hundred and ninety Brazilian women aged 30–65 years, with skin phototype II–VI were equally randomized in two groups. Group 1 kept on their routine whereas Group 2 applied, twice daily, a photoprotective product (SPF 60, PPD = 24.1) replacing the one they routinely used. Volunteers reported the duration of their daily sun‐exposure. Standardized photographs taken at D0 and D365 were analysed by 15 dermatologists to assess eight wrinkles and pigmentation signs. Results: A global increase in severity was reported which was significant for Group 1. This increase was lower in Group 2 where only half the signs showed significant worsening. In Group 2 versus Group 1, the increase in forehead wrinkles, marionette lines, wrinkles created by ptosis and size of dark spot was significantly (p < 0.05) decreased by 30%–50%. Conclusion: Daily application of a high photoprotective product significantly decreases the progression of skin aging signs after 1 year in skin phototypes II–VI. [ABSTRACT FROM AUTHOR] |
