The healthier version of Acrylic.
The Science? Read on!
Technically speaking, hard gel (also called traditional or standard gel) is similar to acrylic in its chemical makeup but has no scent and does less damage. It’s made of monomers plus other ingredients that help the gel remain workable, adhere to the nail, harden properly and resist yellowing. Hard gel is applied to the nail straight from the tube and each layer is cured under a UV/LED light. The curing process creates a strong, compact polymer which can only be removed by filing. After curing, a tacky film of uncured gel, called the inhibition layer, is left and must be removed with nail cleanser.
