SPF + SPF = MORE PROTECTION.
Combining SPFs may seem like a great strategy, but it doesn't increase sun protection. For example, SPF8 + SPF30 = not SPF38.
ALL SUNSCREENS PROTECT AGAINST UVA ANS UVB RAYS.
SPF indicates protection from UVB (burning) rays. To protect your skin from UVA (aging) rays too, use a product labeled "Broad Spectrum".
YOU DON'T NEED SUNSCREEN ON CLOUDY DAYS.
UV rays can penetrate clouds year-round, which is why it's imperative to protect your skin daily.
A BASE TAN PROTECTS YOU FROM THE SUN.
There is no such thing as a safe tan. In fact, a suntan is your skin's defense to being harmed by UV exposure, so slather up!
