Sunscreen

While yesterday's post was about absorption through our skin, today's post is what our skin is absorbing through sunscreen lotions. Please don't get me wrong, I love my Hawaiian Tropical sunscreen but maybe it is just me, sometimes I wonder how safe these lotions are even though they are enhanced with "time-released vitamin A, C, and E"... I will eat extra portions of fruits, vegetables, dairy, and meat...

These are the three main ingredients of my Hawaiian Tropical sunscreen that smells so lovely of coconut:

Octyl Methoxycinnamate (octinoxate) is an organic compound found in lip-balms and sunscreens. This compound can cause photoallergenic effects, can cause endocrine disruption (natural hormones / chemicals in the body that carry messages across the body to repair tissue and manage growth could be interrupted). It is usually combined with another ingredient because once it is exposed to sunlight, it's functioning decreases.

Octyl Salicylate received a score of 4-6 (just as Octyl Methoxycinnamate) compared to titanium dioxide that received a low score of 1-4 on the Skin Deep Cosmetic Database. It is also an organic compound found in sunscreens. Since octisalate (or octyl salicylate) is an insufficient UV-filter on it's own, it has to be combined with something else. When exposed to the sun, octisalate degrades hence is less functioning.

Both octinoxate and octisalate are penetration enhancers, meaning, they are faster absorbed by the skin.

Titanium dioxide, a natural mineral that can safely be used as sunscreen. It is a white, opaque pigment that is used in a variety of ways... from food (white food coloring E171) to tattoo pigment to ceramic glaze to cosmetics where it can be used as thickener as well as functions as sunscreen. Titanium dioxide protects the skin from ultraviolet light. While titanium dioxide itself is considered toxic as the radicals are carcinogenic, fine or coarse titanium dioxide covered with silica or alumina is safe to use for infants and those who have sensitive skin.

After reading up on all the ingredients, it leaves me to wonder why I should put two ingredients on my skin if they are not even doing their job so to speak. I decided to make my own sunscreen lotions with the safest of all evils, titanium dioxide and coconut and almond oils.

Good luck to all sun-lovers!!! May your skin be happy :-)
