Itchy Bumps and Lifting Five Days After a Gel Manicure
A 34-year-old client returns five days after a gel manicure with itching and burning on the skin around six nails. The nail folds are red, slightly swollen, and have tiny vesicles; she also has itchy patches on her eyelids. She says the itching began about 24 hours after the service. Six of ten gel overlays have lifted at the free edge. The technician used a new gel system labeled “HEMA-free,” a 36-watt lamp with bulbs that are nine months old, and 30-second cures for base and color. She applied gel close to the cuticle and cleaned up the edges with a brush after curing. The client had a previous gel manicure two months ago with no reaction. She wants the product removed and a new set applied today because she has a wedding on Saturday.
1. Is this more consistent with irritation or allergic contact dermatitis? Explain the reasoning using the timeline and distribution.

The picture is more consistent with allergic contact dermatitis than simple irritation. Irritant dermatitis usually stays where the irritant touched the skin and causes dryness, redness, and scaling; it does not typically produce vesicles or spread to the eyelids. This client has itching, burning, redness, swelling, and tiny vesicles on the nail folds, plus itchy eyelid patches. The 24-hour delay fits a delayed-type hypersensitivity reaction, which often appears 24–72 hours after exposure. The eyelids are a classic site for transferred acrylate from fingers, which supports an allergic mechanism rather than local friction or harsh soap.
The fact that the product is labeled “HEMA-free” does not rule out allergy. HEMA-free gels can contain other acrylate monomers, and incomplete curing leaves unreacted monomer that can sensitize skin. Old lamp bulbs, short cure times, and gel touching the skin all increase exposure. A previous uneventful manicure does not exclude allergy; sensitization can occur after repeated exposure. The technician should not diagnose, but she should recognize the pattern and stop applying acrylates.
2. What should the technician do today, and what should she tell the client about removal and medical care?
Read the worked answer
She should not apply a new gel set. She should remove the existing gel carefully, avoiding drilling on inflamed skin and avoiding skin contact with acetone or removal tools. If the gel can be filed off without hurting the skin, use a gentle hand file; otherwise use an acetone soak with a barrier, following product instructions. She should wear gloves, ventilate the area, and stop if the client reports increased pain. She should not apply a “protector” or another acrylate product to calm the reaction.
Tell the client: “This looks like a reaction to the product, not an infection I can treat. Please see a dermatologist or your health-care provider before having another gel, acrylic, or dip service.” Advise her not to scratch or pop the vesicles, to keep the area clean, and to use a gentle fragrance-free moisturizer if her provider agrees. She should not use nail polish or artificial nails until cleared. The technician should document the products and lot numbers, cure times, lamp, symptoms, and referral, and should not promise that switching brands will solve the problem.
3. What changes should the technician make to prevent this in future clients, and what should she advise about future nail services?
Read the worked answer
Prevention starts with keeping uncured product off the skin. Use a thin application, leave a small margin at the cuticle and sidewalls, and clean up before curing rather than after. Cure according to the manufacturer’s instructions for the specific gel and lamp; 30 seconds may be too short for some systems. Check lamp bulbs and replace them on schedule, and confirm the lamp is compatible with the gel. Use gloves and avoid touching the face or eyes during the service. Do not assume “HEMA-free” means safe for everyone; other acrylates can sensitize.
For this client, advise that she avoid all artificial nail products until a dermatologist evaluates her. Once sensitized, repeated exposure can cause more severe reactions, and cross-reactions are possible. She should tell future nail technicians and dentists about the reaction. A patch test with the salon product is not reliable and should not be used to “prove” safety. If she is cleared, a conservative approach would be a simple manicure with conventional polish, not another acrylate overlay, unless a dermatologist specifically approves.
