Nail cosmetology.

Nail cosmetics is enjoying growing success due to recent technological advances. Manicures can be responsible for mechanical, infectious or allergic adverse effects. Nail cosmetics (e.g., nail varnishes, acrylic false nails, light-curing gels, and adhesive false nails) incorporate substances that harden after solvent evaporation or after polymerization. Allergic reactions can occur, remotely with conventional varnishes and locally with polymerizing substances. Artificial nails incur a risk of carrying infectious agents which can cause serious infection, and should not be used by caregivers. Recently, there has been a worrisome increase in the frequency of acrylate allergy, due to the appearance of home kits and lack of information in the general public. The infectious, allergic and toxic risks incurred by consumers and professionals regarding manicure or pedicure treatments and the application of nail cosmetics are the subject of recommendations and monitoring measures.
