It may seem like a no-brainer, but selecting the right sunscreen formula and ingredients is almost as important as slathering it on.
"I like to recommend physical sunscreens over chemical ones. Physical sunscreens sit on the surface of the skin and deflect sunlight, while chemical sunscreens absorb sunlight, which creates a chemical reaction that turns UV rays into heat, then releases it through the skin," explains Marino. "The problem with the chemical sunscreens is that the heat that is created can be detrimental for certain skin types, specifically those who suffer from melasma and rosacea."
When looking for physical sunscreen, look for formulas that contain zinc or titanium dioxide. Don't worry! That doesn't mean they will be thick, chalky, and leave you white like a ghost. Many physical formulas are silky and lightweight like Sente Pollution Shield SPF 46 ($49).
"This intelligent formula shields the skin from harmful UV rays, protects from damaging environmental stressors all while detoxifying the skin," note Marino.
