Dark by Rior PRO Base 10, 15ml If you want, I can also help translate product names or descriptions from Spanish to English more naturally.

DARK PRO BASE are low-acidity camouflage bases with a medium consistency, designed to cover the nails with a thin or medium layer.

Description:

• low-acidity camouflage bases (pH 6.5);
• pigmentation level from 1 to 3.5 (on a 4-point scale), with good curing;
• do not peel over time;
• do not cause a strong burning sensation in the lamp;
• rather liquid consistency, which allows for thin and quick leveling;
• they are not rigid, but rather flexible.

Directions for use:
Perform the manicure, buff, degrease the nail, and apply Dehydrator and Ultrabond.
Before applying PRO BASE, it is necessary to apply a thin layer of transparent SCOTCH BASE (or another medium-acidity base) for better adhesion.
This is important because adhesion to the natural nail requires a medium-acidity base. At the same time, remember that leveling should not be done with a medium-acidity base; only a thin layer should be applied 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 the chosen top coat and cure for 90–120 seconds.

Usage details:
It is not recommended to use these bases on long, very thin nails, or for heavily squared shapes with sharp corners. For this type of nail, rigid materials are recommended.
If the client arrives with a nail length that needs to be shortened, it is recommended to do so after applying the top coat (1 mm). This will make the free edge slightly thicker and improve the durability of the material.
