Which component of the artificial nail system is responsible for creating the 'inhibition layer' during the curing process?
- AGel polish
- BPolymer powder
- CNail dehydrator
- DMonomer liquid
Show answer & explanationAnswer & explanation
Correct answer: A. Gel polish
The inhibition layer, a sticky, uncured residue, is characteristic of gel polish and other UV/LED-cured gel products. It forms because oxygen in the air inhibits the top layer of the gel from fully curing, and it's essential for subsequent gel layers to adhere.
Why the other options are wrong
- B. Polymer powder is also part of the acrylic system and cures through chemical reaction, not light, so it doesn't form an inhibition layer.
- C. Nail dehydrator removes moisture and oils from the natural nail, it is a prep product and not involved in forming an inhibition layer.
- D. Monomer liquid is part of the liquid and powder (acrylic) system and does not create an inhibition layer.
Inhibition Layer
A sticky, uncured layer of gel product that remains on the surface after exposure to UV/LED light, caused by oxygen inhibiting the cure. It acts as an adhesive for subsequent layers.
- Unique to gel-based systems.
- Forms after curing.
- Essential for inter-layer adhesion.
- Wiped off only after the final top coat.
