Gel Nails, UV/LED Curing, and Removal
This domain tests gel chemistry, lamp compatibility, curing, and safe removal. Gel requires photoinitiators activated by the correct wavelength, so product and lamp must match.
Curing basics
UV gels typically cure around 365 nm; LED lamps typically emit around 395–405 nm. Not every gel cures in every lamp. Use the manufacturer's matched lamp and cure time. Apply thin, even coats; thick layers may undercure, shrink, or overheat. Keep gel off skin and cuticle, because skin contact causes lifting and allergic reaction. Wipe or leave the inhibition layer according to the system, and do not judge cure only by surface tackiness.
Removal
Break the surface seal with a file, protect the skin, saturate a cotton pad with acetone, wrap or cap the nail, and allow 10–15 minutes. Gently remove softened gel with a wooden pusher; never force, pry, or rip. Rehydrate afterward. If product remains, rewrap rather than scrape hard.
Worked example
A gel overlay lifts at the cuticle after three days. Likely causes are product on skin, a thick cuticle-area coat, or undercuring. The fix is not more top coat; it is proper prep, thinner application, and the correct lamp and cure time.
Traps
Curing UV gel in an incompatible LED lamp, using thick coats, skipping the surface seal before soaking, and forcing removal are common mark-losers.
