PE Cosmetics' Powder Brow pigments are water-based, resulting in a slightly thinner texture that is easily absorbed by the SPMU applicator. The pigments are generally slightly warmer in undertone, except for the shade Ash Blonde, because the colours usually become slightly ashier during the skin's healing process. Compatible with all PE Cosmetics PMU machines and cartridges. An essential supply for any professional salon offering PMU services.
