Whether it's a classic nail polish application, nail art or semi-permanent, this moment is pleasant and makes you feel better about your body. However, we don't really imagine that the products that we use are particularly harmful to our health. Why is this? Because they are not subject to strict regulations.Scientists have found toxins in several varnishes marketed by some of the most popular cosmetic brands.Nail polish: be careful with childrenThe endocrine disruptors found by the scientists are TPHP, or triphenyl phosphate, methanal and toluene. These toxic elements allow the varnish to be flexible and more resistant. However, when in contact with blood, these products can affect hormones, metabolism and reproduction.26 women were tested for the study. Ten hours after applying nail polish, their HPTP levels had increased. One of the potential effects of HPTN is that it can have a negative impact on the development of children during pregnancy.
