CHAPTER 10 — GEL SYSTEMS (Soft Gel, Hard Gel, Builder, Gel Polish)
Louisville Beauty Academy (LBA) — YES I CAN™ Master Gel Systems Safely & Professionally
Gel systems have become one of the most popular services in the nail industry because they are:
- lightweight
- flexible or strong (depending on type)
- long-lasting
- low odor
- beautiful and shiny
But gel requires precise technique and high awareness of allergic risk, because:
- uncured gel touching the skin can cause allergies
- under-curing leads to lifting
- over-curing causes brittleness
- wrong lamp/cure time weakens the nail
- poor prep leads to peeling
- living skin must never be filed or flooded
Louisville Beauty Academy teaches:
“Gel is chemistry, control, cleanliness, and curing.
Respect the process, and the product will respect you.”
