How can cosmetics "pollute" the body
Often unloved, the pores of the skin are nevertheless very useful: they allow the body to breathe and regulate its temperature thanks, in particular, to perspiration. But these pores also make the skin a real "sponge": if some molecules are far too large to penetrate, others can easily pass through and then find themselves free in the body.
Thus, each product coming into contact with the skin is likely to penetrate it. A godsend for endocrine disruptors, small molecules that go into the composition of a large number of cosmetics...

Endocrine disruptors, what?
Indeed, when they are not bio, most of cosmetics contain significant amounts of endocrine disruptors such as phthalates (found in perfumes), parabens (found in many shampoos), triclosan (in some antibacterial soaps) and oxybenzone. Endocrine disruptors are particularly small molecules, which allows them to easily pass through the pores of the skin and thus reach the body. Endocrine disruptors directly affect hormone regulation, which can cause thyroid disorders, puberty and fertility.
It's proven ! Certified organic cosmetics, the alternative that is good for you
However, do not panic, it is possible to look beautiful while preserving your health.
Indeed, a study by the University of Berkeley and the Clinica de Salud del Valle de Salinas asked a hundred young girls to integrate certified organic cosmetics into their daily routine. Make-up and body hygiene products included. The verdict was final: after only three days of using certified organic cosmetics, the endocrine disruptors contained in the urine of the candidates have dropped dramatically: -27% phthalates, -44% parabens and -36% triclosan and benzophenone. The person responsible for this study was so "shocked" by the results that she changed her own consumption of beauty products and opted for certified organic cosmetics !
