Itching and Vesicles During a Gel Full Set
A 29-year-old client has worn gel extensions continuously for eight months. She books a new full set before a two-week vacation. During application she reports itching and a burning sensation on her fingertips and eyelids. You notice redness and tiny vesicles along the lateral nail folds and fingertip skin. She has been using a HEMA-based builder gel and a primer; you have been wiping excess product onto her skin and curing with a 36-watt UV/LED lamp. She says the last two sets lifted within a week, so she wants 'extra strength' and a second primer layer. She has no fever, pus, or streaking. She asks you to finish because she leaves in two days and has no time to see a doctor.
1. What is the likely reaction, and what should you do right now?

The itching, burning, redness, and tiny vesicles, especially on the eyelids, point to allergic contact dermatitis from acrylates rather than a normal cure sensation. Eyelid involvement is a classic sign of transferred acrylate; wiping excess onto skin increases exposure. A reaction after repeated exposure fits sensitization. It is not clearly an infection because there is no pus, fever, or streaking, but you cannot diagnose. Stop the application, do not add more primer or 'extra strength' product, and do not try to finish because she is traveling. Remove uncured product with the manufacturer's remover, wash the skin with soap and water, and refer her to a dermatologist or physician. Document the products, lot or batch numbers, and symptoms. If she has severe swelling or trouble breathing, she needs urgent care.
2. What aftercare and product advice should you give, and what should you avoid claiming?
Read the worked answer
Advise her to tell the doctor which products were used and to avoid other nail products until cleared. Do not apply another acrylate-based product, including a HEMA-free gel, until a medical professional approves it; 'HEMA-free' does not mean acrylate-free. Do not claim that a patch test in the salon will prove safety or that the reaction will disappear if she switches brands. Provide aftercare: no scratching, no harsh soaps, no picking, and no home gel kits. If the reaction spreads or she develops pus, fever, or streaking, she should seek care promptly. Document the advice and her decision. For future services, avoid skin contact, use thin layers, cure fully with the correct lamp, and never use primer on skin.
3. What application errors likely contributed, and how should they be corrected?
Read the worked answer
The lifting and repeated primer suggest application error and overexposure. Use the lamp specified by the product manufacturer, check lamp age and bulbs, cap edges cleanly, and do not touch skin with gel or primer. Never apply primer to skin. Do not mix brands unless the manufacturer supports it. Work in a ventilated area, wear gloves, and keep safety data sheets available. The salon should have a written exposure-response policy. If the client is sensitized, she may never tolerate acrylates again; after medical clearance, a natural manicure with conventional polish may be safer. Do not guarantee that a new set will be fine. The goal is to prevent sensitization in every client, not just to finish this appointment.
