Most regular sunscreens are cocktails of chemical agents that are not very good for your health. Since your skin is semi permeable, it lets through most of these agents. In the long run (and together with al the other toxic cosmetic products you might be using) they can intoxicate your body to a level of minor or even serious health problems.
A sample of what you’re likely to find on the label of your favorite sunscreen:
1. Parabens
‘Endocrine disruptors’ These gender-bending chemicals mimic estrogen, upset your hormonal balance, and can cause various reproductive cancers in men and women.
2. PABA (may be listed as octyl-dimethyl or padimate-O)
Attacks DNA and causes genetic mutation when exposed to sunlight
3. Mineral oil, paraffin, petrolatum
Coats skin like plastic and clogs pores, trapping toxins in, slows skin cell growth, disrupts normal hormone function, suspected of causing cancer.
4. Sodium laurel, lauryl sulfate, sodium laureth sulfate (sometimes listed as ‘from coconut’ or ‘coconut derived’)
Combined with other chemicals, it becomes nitrosamine, a powerful cancer-causing agent; penetrates your skin’s moisture barrier, allowing other dangerous chemicals to enter your bloodstream.
5. Phenol carbolic acid
Can cause circulatory collapse, respiration problems, paralysis, convulsions and even coma.
6. Acrylamide
Associated with (breast) cancer.
7. Octyl-methoxycinnamate (OMC)
Kills skin cells.
8. Toluene (may be listed as benzoic, benzyl, or butylated hydroxtoluene)
Promotes anemia, low blood cell count, liver and kidney damage, birth defects.
9. Propylene glycol
Can cause skin irritation, dermatitis, kidney and liver abnormalities, prevents skin growth.
10. PEG, polysorbates, laureth, ethoxylated alcohol
Potent carcinogens containing dioxane.
SOLUTION
Buy sunscreen from your organic store or don’t stay in the sun for too long. To get your skin to produce the necessary vitamin D, half an hour of full sun exposure per day is enough (without using sunscreen, by the way, which prohibits the skin from producing vitamin D!).
Unless you have a very sensitive skin: if you use hydrating skin lotions and you don’t overexpose to the sun, you don’t really need sunscreen.
