DARK PRO BASE is a low-acid camouflaging base of medium viscosity designed for thin or medium nail application.Description: Low-acid (pH 6.5) camouflaging bases; Pigmentation level from 1 to 3.5 (by 4-point scale), cures well; Does not delaminate over time; Does not cause strong burning sensation in the lamp; Consistency is closer to liquid, which allows for quick and thin leveling; Not rigid, closer to flexible texture. How to use: Do a manicure, buff and degrease the nail, apply Dehydrator and Ultrabond; Before applying PRO BASE, apply a thin layer of a transparent SCOTCH BASE (or another medium-acid base) for better adhesion:This is important, because medium-acid base is necessary for good adhesion to natural nails. Note: do not use a medium-acid base for leveling, only a thin layer to prevent chemical burns. Apply a thin or leveling layer of DARK PRO BASE. The thickness of the layer should not exceed 0.7 mm. Cure for 60-90 seconds in an original lamp. Apply the chosen top coat and cure for 90-120 seconds. Work nuances: We do not recommend using this base on long, very thin nails or for a strict square shape with sharp corners. Use harder materials for those cases. If your client wants to remove some length, we recommend trimming after applying the top coat (up to 1 mm). This will keep the edge slightly thicker and improve wear resistance. Available in 2 volumes: 15 ml with brush / 30 ml without brush.
