Not all SPFs are cre­ated equal. TRUTH.

When choos­ing sun pro­tec­tion, start by look­ing for the words broad­spec­trum on the la­bel. “These sun­screens pro­tect against both UVA rays, which cause pre­ma­ture ag­ing; and UVB rays, which cause burns and can lead to can­cer,” ex­plains Deb­o­rah Sarnoff, a New York City der­ma­tol­o­gist and pres­i­dent of the Skin Can­cer Foun­da­tion. Next, pay at­ten­tion to the SPF num­ber. Doc­tors rec­om­mend wear­ing at least SPF 30 at all times.

Makeup with SPF is prefer­able. TRUTH.

Most peo­ple don’t use enough sun­screen or ap­ply it un­evenly, so an SPF- en­hanced primer or foun­da­tion pro­vides a solid sec­ondary line of de­fense. The Skin Can­cer Foun­da­tion rec­om­mends wear­ing a nickel-size dol­lop of sun­screen on the face; over the en­tire body, use a full ounce (the amount that would fill a shot glass). Reap­ply ev­ery two hours, es­pe­cially be­tween the hours of 9 A.M. and 3 P.M. (when the sun is the strong­est).

Sun­screen is dan­ger­ous. LIE.

Claims about sun­screen be­ing ab­sorbed in your blood­stream have cir­cu­lated for years. And while re­search is al­ways on­go­ing, “based on ex­haus­tive stud­ies and re­view, we know that UV- block­ing in­gre­di­ents like oxy­ben­zone do not ac­cu­mu­late—the body ex­cretes them, mak­ing sig­nif­i­cant buildup vir­tu­ally im­pos­si­ble,” says Sarnoff. What’s more, there’s an un­ques­tion­able link be­tween sun ex­po­sure and skin can­cer, so lo­tion up with a broad-spec­trum SPF. There are loads to choose from.
