The Lovely Aloe Primer is the product developed by Lovely's own laboratory. Contains natural extracts and care ingredients. Tested together with lash technologists and craftsmen. Thanks to the special cap with 3D logo, Lovely primers are very difficult to counterfeit. This is a guarantee that you are purchasing a quality product. The slightly alkaline pH of the primer helps prepare the natural lashes for the extension process and promotes better polymerization of the adhesive. Each box contains instructions with a pH scale and two strips of litmus paper to determine the acid-base balance of any other product.
