The COPINES Line hardening varnish easily penetrates the 3 layers of the nail to harden and strengthen them. Thanks to its slightly nude shade, it will give shine and shine to your natural nails.

Composition & Specifications

Nails are formed from keratinized structures from the epidermis, the basic composition of which is water + keratin and lipids. It is essential to moisturize it and enrich it with lipids.


FORMULA: The new compound is a complex of biodegradable particles containing keratin + vitamin E + arginine + tea tree oil, in the form of lipid microspheres encapsulated with active ingredients and vegetable oils. The hardener also contains omega 3 and 6 of plant origin.


The advantage of using an encapsulated compound in the formula is to have a more stable formula and to have a homogeneous release of each active ingredient on the nail.
