formaldehyde, toluene and dibutyl phthalate in varnishes, which manufacturers mark as free from these substances.
But do not rush to throw away all your varnishes. There is no evidence that these substances somehow affect health in the composition of varnishes (but to use them inside, of course, is not necessary).
The United States Food and Drug Administration (FDA) considers that these three substances can be used in varnishes. However, the FDA has a clarification about formaldehyde: it can brittle nails, cause skin irritation and allergic reactions.
The main complaint about gel polishes is an ultraviolet lamp.
You need to put nails in it so that the gel polish hardens. Such lamps emit UV rays from spectrum A, as do the solarium . These rays can cause premature skin aging and skin cancer. Nevertheless, in 2014, the researchers tested 16 manicure lamps and decided that in general they were not so dangerous. However, UV lamps vary greatly in power.
Therefore, it is not worth making any definite conclusions about their harm or harmlessness - more research is needed on this subject. Cases of skin cancer after using a UV lamp are now described not so much, or rather, only two . And in both cases, it cannot be argued that it was the lamps that caused the cancer. Nevertheless, experts advise applying sunscreen with SPF at least 30 twenty minutes before the procedure.
