The paint is incredibly economical and lasts for about a year on average. The product does not remain on the skin, therefore it does not have a tattoo effect. The color intensity can be adjusted by the dwell time of the paint. The resulting shade lasts 3-4 weeks on the eyelashes and eyebrows. Due to its soft consistency and neutral pH level, the product does not bake and does not cause unpleasant sensations during coloring.
