Physical versus chemical sunscreens
Protecting your skin from the sun goes far beyond simply slathering on sunscreen. While this is undoubtedly a first and important step in your skin-care routine, not all sunscreens are created equal. Some come in higher SPFs, which determine how well they protect your skin from the sun, as well as different sets of ingredients. The two main types of sunscreens are physical and chemical. “Physical sunscreens sit on the top of the skin and deflect or scatter damaging UV rays away from the skin and are mainly made up of titanium dioxide and zinc oxide,” explains Dendy Engelman, MD, New York City-based dermatologist. “Chemical sunscreens work by absorbing UV rays, converting them into heat and then releasing, and mainly consist of oxybenzone, octinoxate, octisalate, octocrylene, homosalate, and avobenzone, or a combination of these.” The best way to determine which sunscreen will work best to protect your skin and treat other concerns you may have such as oiliness, dryness, or signs of aging, is to choose a brand that’s formulated for your skin type.
