UV Gel Nail Enhancements
What this domain tests
UV gel questions cover chemistry, curing, layering, lamp use, removal, and allergic reaction risk. Expect comparisons among gel polish, hard gel, and acrylic.
Core rules
- Gel is made of oligomers and photoinitiators that cure only under the correct UV/LED wavelength and time. Thin layers cure more reliably than thick ones.
- Use the manufacturer’s base, color, and top coat as a system. Do not mix brands or cure times unless the maker confirms compatibility.
- Keep gel off skin; uncured gel on skin is a common cause of acrylate allergy. If gel touches skin, remove it before curing.
- The inhibition layer is the tacky surface left after curing; follow the system-some layers bond through it, and a top coat may need wiping after cure.
- Maintain lamps: clean bulbs/LEDs, replace as specified, and do not assume every LED lamp cures every gel.
- Remove by soaking in acetone as directed; never force or pry product off.
Worked example
Gel polish peels in sheets after two days. Possible causes are undercuring, too-thick layers, or application over cuticle. Check lamp condition, use thin coats, and clean the margin. Reasoning: uncured or skin-bonded gel has a weak edge that lifts and lets solvent and air under the coating.
Traps that cost marks
- “LED cures all gels.”
- Curing a thick bead in one pass.
- Wiping the inhibition layer at the wrong stage.
- Calling gel a nail strengthener or treatment.
