Most Sunscreens are affected by ultraviolet (UV) sunlight.
Most sunscreens degrade when exposed to sunlight. Yep! - You read that correctly.
One more time, just in case you missed it... Most sunscreens degrade when you go into the sun! As soon as you go into the sun, the degradation process beings.
Even though zinc is the best active ingredient to reduce UV absorption into the skin, when exposed sunlight, organic materials, like zinc, decompose on the skins surface and release free radicals that work to kill cell membranes.
The science behind 3rd Rock SunBlock's patented zinc oxide shines! The zinc oxide used in 3rd Rock SunBlock is inorganic and chelated, in other words attached, with another molecule, l-Argenine (an amino acid). With this chelation, the zinc oxide dispersion acquires a superior stability. There is NO breakdown in the presence of UV light and it therefore absorbs UVA better than any other brand. Period.
Most sunscreens degrade in the presence of the sun - Not 3rd Rock Sunblock.
