Summer may feel like a distant memory, but skin damage from all those patio dates hasn’t been forgotten. “Light reflecting off skin is what makes people look younger,” says Dr. Julia Carroll of Compass Dermatology in Toronto, who explains that wrinkles and pigmentation hinder light’s ability to bounce off your face. Now is the season to repair. Derm treatments such as peels and lasering require that you limit sun exposure to avoid pigment change—easy to do when it’s dark by 5 p.m. Look for brightening products with kojic acid, vitamin C, glycolic acid or Retin-A.
