Look for ones made with micronized titanium dioxide or coated zinc oxide—they leave less of a film when applied to skin. Or check the ingredients label for chemical sunscreens such as avobenzone, oxybenzone and homosalate, which won’t leave behind tell-tale white streaks, says Wendy Roberts, M.D., a dermatologist in Rancho Mirage, California. What to avoid: sunscreens that contain traditional formula physical blockers like uncoated zinc oxide and unmicronized titanium dioxide, which reflect rays. These blockers have large particles and tend to sit on top of the skin, giving it an ashy look. “However,” Strachan adds, “these ingredients are considered safer and more natural.”
