DARK PRO BASE is a low-acid camouflage base of medium consistency, designed for thin or medium layer application on nails.Description: Low-acidic (pH 6.5) camouflage bases Pigmentation level from 1 to 3.5 (on a four-point scale), cures well Does not separate over time Does not cause intense burning in the lamp Has a consistency close to liquid, allowing for quick and even application Not rigid, more flexible/plastic Directions for use: Perform manicure, buff and degrease the nail, apply Dehydrator and Ultrabond Before applying PRO BASE, apply a thin layer of clear SCOTCH BASE (or another medium-acid base) as an underlay for better adhesion.This is important because medium-acid base is required for adhesion to natural nails; remember, aligning should not be performed with a medium-acid base, only a thin layer to avoid chemical burns. Apply a thin or leveling layer of DARK PRO BASE. The layer thickness should not exceed 0.7 mm. Curing time is 60-90 seconds in an original lamp. Apply your chosen top coat and cure for 90-120 seconds.
