Base and top for gel polish are a must in the work of the master. Gel polish is applied to a special base (base) and fixed with a top (finish). The base evens and strengthens the nail plate, provides good adhesion of the gel polish and prolongs its wear period. The top coating protects the nail design from aggressive environmental influences: ultraviolet radiation, detergents, moisture, mechanical damage. The top also seals the free edge of the nail, which prevents the coating from peeling off.
