Another good news is that the cosmetics have a long-lasting effect . Once the gel color has completely dried, the results will last for a few days. Repeat the treatment once a week and forget about eyebrow tinting for the rest of the week. The product's special formula has a nourishing effect on your eyebrows , giving them a fuller, more defined and healthier look, even if your eyebrows are naturally sparse. Look like a star and feel like one every day!
