Various incarnations of DIY face masks involving raw egg whites have become popular over the years and they generally seem to work well. After all, egg whites contain proteins and collagen, two ingredients that can help improve skin elasticity and firmness. But using it directly on your skin can pose some risks: Raw eggs can contain food poisoning-causing bacteria such as salmonella, which is hardly good for your skin.
Plus, though egg whites have a lot of natural nutrients, not all of them would actually be absorbed by your skin. The collagen in egg whites can't penetrate to the deeper layers of the skin, so its effect is just temporary. That said, if you swear by egg whites for your skin, you can always use skin care products made with this ingredient to be on the safe side. (We love the SkinFood Egg White Pore Steam Pack)
