A Survey of Skin Reactions Associated With Acrylic Nail Cosmetics, With a Focus on Home Kits: Is There a Need for Regulation?

Background: Sensitization to (meth)acrylates, the most common nail cosmetic allergens, is rising. In recent years, home acrylic nail kits have become easily available.Objective: To investigate the characteristics of individuals reporting skin reactions associated with acrylic nail cosmetics, particularly home kits.Methods: Cross-sectional survey of Facebook nail allergy support groups. Inclusion criteria were self-reported skin reactions associated with acrylic nails and age >= 18 years.Results: There were 199 respondents, nearly all female (99%), mostly white (83%), and 25-54 years old (83%). Seventy-eight percent reported using home acrylic kits, more than half for the first time during COVID-19. They predominantly learned about kits through social media (68%) and received training through websites/online videos (74%). Most home users (83%) first developed skin reactions after starting to use home kits. Compared with nonhome users, significantly more home users reported skin reaction onset within 1 year of use, as well as nail damage (P < 0.05).Conclusions: Among online nail allergy support group members, home acrylic nail kit use was common and associated with earlier development of skin reactions and more frequent nail damage than professional acrylic manicures. These findings raise important questions about the need to regulate home acrylic nail kits.
