HD Skinliner is applied easily and conveniently. The soft silicone tip draws a precise line, and the color ink demonstrates excellent adherence to the skin, without running. HD Skinliner is waterproof. Kryolan Eye Make-up Remover is recommended for removal of waterproof Skinliner. Note: After long use of Skinliner, the soft silicone tip can wear out. To extend the life of the liner, just pull out the tip, turn it around, and replace it. This restores the original precision.
