Bio Sculpture® Clear Gel is a Flexible Gel used as a nail hardening treatment to strengthen and condition natural nails. It is applied onto a prepared nail and cures for two minutes under a 9-watt UV-A lamp. It is used as a first layer for color, clear and French overlays giving better adhesion for all gels. It is also used to build a flexible upper arch when doing sculptures and as a last layer over dark color overlays for a shiny finish.
