With so many companies launching high SPF number sunscreens, it creates a lot of confusion as to which number is the best in protecting your skin. As a skin care expert and celebrity esthetician, I’ll share some interesting (and surprising!) facts and myths in regards to which SPF number you should be using to keep it protected from the damaging rays.
FACT: SPF 30 offers only 4% more sun protection than an SPF 15. And an SPF 45 offers only 2% more than an SPF 30. The higher up you go, that percentage lessens. The real secret to protecting your skin from harmful UV rays is to reapply often and generously—it’s really not the SPF number that matters.
FACT: Your skin needs both UVA and UVB protection. The SPF number only applies to UVB—the sunburn causing rays. The other rays—UVA rays— are the aging rays which breakdown collagen and elastin that cause wrinkles. Zinc Oxide is an excellent UVA and UVB sunscreen. It’s also offers anti-inflammatory properties so it’s excellent for sensitive skin. I highly suggest either the Daily Protection SPF 30 or Age Defense Moisturizer SPF 30 since they both contain Zinc Oxide which is the best sunscreen ingredient on the market for protecting sensitive skin…

FACT: SPF 30 is plenty. High SPF numbers like SPF 100 can give a false sense of protection and consumers may not apply it generously enough. Plus, if you’re someone with sensitive skin, the higher SPF number may contain more chemical additives, resulting in skin reactions and irritations.
FACT: Most sun protection products for babies don’t go over SPF 50 and there’s a reason—more irritating chemicals!
Bottom line: An SPF 30 with broad spectrum UVA/UVB protecting Zinc Oxide will keep your skin safe and protected as long are you’re applying (and reapplying) generously.
By the way, the FDA is proposing to limit the maximum SPF on labels to 50.
