Gel allergy is a real condition affecting 2-5% of regular gel wearers. Here is what you need to know.
HEMA (hydroxyethyl methacrylate) is a monomer used in most gel polishes and some gel top coats. It is the ingredient that reacts under UV light to form the hard polymer. In some people, HEMA triggers a type IV contact dermatitis (delayed allergic reaction). The body's immune system identifies HEMA as a threat and reacts when it contacts the skin. The allergy develops over time — you can use gel for years and then develop a reaction. Repeated exposure increases the sensitivity. Once you are allergic to HEMA, every future gel service will trigger a reaction if HEMA is present.
Symptoms appear 12-48 hours after a gel service: itching on the skin around the nails, redness, small blisters, peeling skin, and dry cracked skin on the fingertips. Severe cases: the nail plate itself can separate from the nail bed (onycholysis). The reaction is localised to the fingers — it does not spread to the rest of the body. If you see these symptoms: stop gel services immediately. Remove the gel (have a Jeannie Nails technician remove it — do not attempt removal at home, the acetone and filing can worsen the reaction). Switch to a HEMA-free gel or switch to dip powder (dip powder uses a different resin system — cyanoacrylate, not methacrylate. Allergy to dip is rare).
We carry a HEMA-free gel line (the base coat and top coat contain no HEMA — the colour gel does not contain HEMA either). 90% of gel allergy sufferers can wear HEMA-free gel without a reaction. The HEMA-free line has the same durability and finish as standard gel. Inform your technician at the appointment if you suspect a gel allergy. They will select the HEMA-free products and monitor for any reaction during removal.
Prevent gel allergy before it develops: ensure no gel touches the skin during application (a good technician keeps the gel on the nail and off the cuticle — gel on the skin increases the risk of developing an allergy. At Jeannie Nails, all technicians are trained to keep gel off the skin). Do not let anyone over-file the natural nail (aggressive filing thins the nail and increases exposure to monomers through the nail plate. The filing should remove the top coat only — not the natural nail). Do not get gel services if the skin around the nails is broken, cracked, or cut (the monomer enters the bloodstream faster through broken skin, increasing the allergy risk). Take breaks from gel (go without gel for 4-6 weeks every 6 months. This allows the nail plate to recover and reduces cumulative monomer exposure).
HEMA-free gel available at Jeannie Nails.
