Builder Gel In The Bottle (Brush-On) – KUPA EnrichRx Perfect Peach – a brush-on builder gel for natural-nail overlays, light extensions, and structured manicures in a soak-off formula.
What It Does
KUPA EnrichRx is a brush-on builder gel-in-a-bottle for nail technicians who want apex structure without the labor of pot-and-spatula application. The medium-viscosity formula self-levels under controlled application, builds an apex for strength, and soaks off with 100% acetone (unlike traditional hard gel). Cures under UV or LED in the standard gel polish workflow.
Why Pros Choose This
Brush-on bottle format: No spatula required – apply like gel polish, build apex with the bottle brush.
Self-levels controlled: Settles without flooding the cuticle, giving structured shape with practice.
UV and LED cure: Fits the same lamp cycle as your gel polish system.
Soak-off removal: Acetone-removable with file-and-soak protocol (10-15 minutes).
How to Use
-
Prep nail: cuticle push-back, light buff, dehydrate.
Apply base coat thin, cure 60 seconds LED.
Apply EnrichRx Perfect Peach in slip-layer first, then build apex with the brush.
Cure under LED for 60 seconds (2 minutes UV). Refine the apex with a file or e-file once cured.
Apply color gel polish, finish with top coat.
Best For
Home-studio pros and salon techs adding apex structure to weak natural nails, doing short overlays, or building base shape under a gel polish manicure. Suits beginners more easily than hard gel.
