According to studies FDA has approved 17 active sunscreen ingredients which should be present.
It should include following:
Ecamsule (Mexoryl SX)
Ensulizole (Phenylbenzimidazole Sulfonic Acid)
Meradimate (Menthyl Anthranilate)
Octinoxate (Octyl Methoxycinnamate)
Octisalate (Octyl Salicylate)
Apply sunscreen before you go outside. It can take about 15 minutes for it to be absorbed into the skin — if you wait until you get outside, you will be unprotected for that time….not true….
You wouldn’t have to do this if you purchase and use a natural sunscreen that contains Zinc Oxide…it’s the nasty chemical sunscreens (eek) that that have to absorb into your skin before they start working.
Zinc Oxide sunscreen works immediately!
I can’t believe this article doesn’t mention that most products that claim to be sun screens don’t even include the vital ingredients that actually provide that protection–namely zinc and/or titanium.
