Skin experts are warning that chemicals used in acrylic and gel nail polish may induce an allergic reaction.
Methacrylates appear to be the culprit, causing rash and itching not only in the fingers but other parts of the body, including genitalia. Some may experience losing their nail after a reaction.
Once the immune system is triggered, allergic symptoms could surface in other parts of the body.
The British Association of Dermatologists warns 2.4% of the population could be at risk.
The nail industry is a multibillion dollar industry with hundreds of thousands of customers each year.
Methacrylates are used in a variety of industries in adhesives, plastics, paints and even medical and dental devices.
Eyelash glue and home nail kits can also expose users to methacrylate. Many have reported allergic reactions of their eyelid after having lash extensions applied.
In the above study 4900 people were evaluated in Irish and British dermatology clinics with study authors finding of those allergy tested, 2.4% were found reactive to methacrylate.
The reactivity could put one at risk of a dangerous allergic reaction, such as anaphylaxis if exposed during a medical/dental procedure using a similar resin.
Consumers should be aware that if they are experiencing itching or rashes on other parts of the body, it may be stemming from their fingertips.
