Sunscreen Made Simple: What You Really Need to Know
UVB rays mostly cause sunburn and they are filtered by windows
UVA rays mostly cause wrinkles, sagging and aging, and they blast through windows
SPF numbers ONLY apply to UVB, and SPF 30 keeps out 97% of UVB rays
All sunscreens need to be re-applied after 2 hrs if you are out in the sun
All sunscreens need to be re-applied after swimming or sweating excessively
No sunscreen is perfect, wear a hat and apply enough to protect you
A day at the beach will require 1/4 to 1/2 an 8oz bottle of sunscreen
Different types of sunscreens protect against different types of rays
UVB chemical blockers include chemicals such as octinoxate, octisalate
UVA chemical blockers include avobenzone, and oxybenzone
Safety concerns have been raised about avobenzone, oxybenzone and other chemical blockers but only 1-5% of what you put onto your skin actually penetrates it
UVA and UVB physical blockers include zinc oxide and titanium dioxide
Chemical sunscreens need 30 minutes to bind to the skin before they are effective
Physical sunscreens, (zinc & titanium), are effective immediately
Sunscreen does not cause Vitamin D deficiency, this is a myth
Sunscreen is still necessary on cloudy days
Look for a sunscreen, like PCA, with the “Skin Cancer Foundation seal of approval
PCA sunscreen has both chemical (octinoxate), and zinc oxide for full protection
PCA has a new physical only tinted sunscreen, with both zinc and titanium
