Chemical (Organic) vs. Physical (Inorganic)
The most common sunscreens contain “chemical absorbers”, such as PABA, which are carbon compounds made in a lab. Physical blockers like zinc oxide and titanium dioxide are natural minerals ground into fine powders and do not decompose the way chemical blockers do.
When sunlight hits the skin, chemical absorbers absorb active UV rays and release their energy in harmless ways, while physical blockers reflect the rays without allowing skin penetration.
While physical blockers are preferred, a minimum of SPF 15 should be applied every two hours while in the sun. Do not apply to babies younger than six months, who should be kept out of the sun.
