Know the risk

HEMA exposure can
lead to sensitization.

Uncured gel on skin and repeated exposure can contribute to allergic contact dermatitis. If you suspect a reaction, stop use and ask a qualified clinician about diagnosis and related methacrylates.

Common Questions

Why is HEMA flagged in nail products?

HEMA (2-Hydroxyethyl Methacrylate) is a well-recognized contact allergen used in gel nail products. Repeated or uncured skin exposure can contribute to sensitization; people with suspected reactions should stop use and seek advice from a qualified clinician.

What is a builder gel?

Builder gel is a thick, UV/LED-cured gel used to extend or strengthen natural nails. Unlike regular gel polish, it has enough structure to add length. BIAB (Builder In A Bottle) is a thinner variation applied like nail polish directly on the natural nail.

How do I check if my gel polish is HEMA-free?

Use our ingredient checker — search the product name and we'll flag any sensitizing ingredients. Look for '2-Hydroxyethyl Methacrylate' (HEMA) or 'Di-HEMA Trimethylhexyl Dicarbamate' on the label.

What should I use instead of HEMA-containing gels?

There is no universally allergy-safe substitute. Compare the complete current disclosure, remember that HEMA-free products may contain other acrylates or methacrylates, avoid uncured product on skin, and ask a qualified clinician for advice if you have symptoms or a confirmed allergy.

Can nail technicians develop HEMA sensitivity?

Occupational exposure can increase contact with uncured gel. Appropriate gloves, avoiding skin contact, correct curing, ventilation, and reviewing product disclosures can help reduce exposure; HEMA-free labels alone do not make a product allergy-proof.
