Here Comes the Sun
Did you know that...
-- UVB chiefly causes sunburn, while UVA rays, which penetrate the skin more deeply causes photoaging.
-- Ultra Violet Rays can penetrate glass eventhough it can filter UVB. Which means that even if you're inside your house or car, as long as you are sitting next to a window, you're at risk for UV damage. Especially if you drive on a frequent basis, I highly recommend covering your car windows with UVA-protective film(which block out up to 99.9 percent of UVR).
-- Up to 40 percent of the sun's ultraviolet radiation reaches the earth on a completely cloudy day.
-- Regardless of strength, sunscreeen should be reapplied every two hours. Transluscent powder sunscreen such as Peter Thomas Roth Instant Mineral SPF 30 is a great alternative to cream or lotion products as it can be reapplied over makeup.
-- Reddening of your skin is only a reaction to the UVB rays – it does not tell you what UVA damage you might be getting.
-- It takes 30 minutes for the sunscreen’s ingredients to bind to the skin. I apply two generous layers of moisturizing sunscreen with broad-spectrum protection on bare skin each morning – do not wear a moisturizer underneath your sunscreen unless it is a light antioxidant serum, as it will dilute the effectiveness of the active ingredients.
-- Check the ingredients of the sunscreen to make sure it offers broad-spectrum protection. Cheap yet effective choice even for acne prone skin: Neutrogena Healthy Defense Daily Moisturizer Spf 45.
