The glycerin ruler (black) was created as an alternative to the hydroalcoholic ruler (white ruler).

The composition of chemical dyes in each of the pigments was analyzed and selected based on light fastness parameters. This makes it possible to observe the stability of the pigment in use long after the procedure. Glycerin softens the skin during the procedure, helps restore damaged tissue and accelerates the healing process, which is especially important on the delicate skin of the lips.
