No matter what season it is, skin cancer still on the rise!
Fact or Myth–-The higher the “Skin Protection Factor” (SPF) rating, the better the protection
Myth – SPF ratings only refer to protection from UVB (burning rays), NOT the more damaging UVA aging rays. Therefore, a higher SPF gives a false sense of security. For example, a SPF of 50 is only marginally more protective than an SPF of 15; an SPF of 30 has only 2% more protection than an SPF of 15, and a SPF of 40 has only 1% more than a 30. Sunscreens need to be reapplied every 90–120 minutes to insure adequate protection.
Fact or Myth –– If you wear a moisturizer with SPF, then you do not need to wear sunscreen
Myth – These moisturizers (and liquid foundations) do not “offer broad spectrum” protection from UVA (aging rays) and only offer minimal protection from UVB (burning rays) so additional sun protection is recommended. A good coverage mineral powder is best since its ingredients already provide excellent sun protection due their mineral content.
Fact or Myth – Layering several products with SPF ratings increases protection
Myth – You are only protected to the extent of the higher rating of one product. A foundation with an SPF of 10, moisturizer with an SPF of 15 and a sunscreen with an SPF of 20 does not yield an SPF rating of 45.
