“Thin Skin” is a solid-surface ultra-thin polyurethane hair system base material. At its thinnest, it’s similar to a contact lens. It is non-porous, so air, sweat, and water will not pass through the base, but It’s light enough to be comfortable in hot conditions and it has a very realistic appearance. It offer you a natural look and it will blend in with your own skin seamlessly. Our Ultra-thin skin base is about 0.03 mm, which will be easy to forget that you are even wearing one. Our thicker skin bases provide you with a longer lifespan and better durability at the same time. Thin skin base is also called PU (polyurethane) for those who are familiar with it's material.
