In general, Anna Kutsevolova, the creator of Brovi pigments, recommends always adding about 10% of dilutor to the regular Brovi line (1 drop of dilutor per every 9 drops of pigment). That way the brows will heal naturally and soft.
For oily and porous skin, add 10% of dilutor.
For sensitive skin, add 30% of dilutor.
For mature skin, add 30 – 40% of dilutor.
For dry skin, 40-50% of dilutor.
