Silicone skin, widely used in high-end dolls, embodies a balance of elasticity, durability, and safety. The material is a two-part polymer that cures into a flexible, skin-like elastomer. Its durometer rating, a measure of hardness, influences how the surface feels and moves. Lower duros feel softer and more lifelike, while higher duros resist tearing and wear. Pigments are mixed into the silicone to achieve realistic skin tones and subtle veining, with shading layered to create depth and character. Silicone’s non-porous nature helps with hygienic cleaning, though it can attract dust and oils if not cared for properly.
Silicone skins also respond to temperature; they conduct heat similarly to human skin but are not living tissue, so they don’t feel temperature in the same way. Resistance to tearing, abrasion, and chemical exposure varies with formulation and thickness. For care, mild soaps and water are generally safe, while aggressive solvents can degrade the surface. Special care should be taken to avoid sharp objects that could puncture or cut the skin. Over time, silicone can experience aging or yellowing if exposed to harsh UV light and certain chemicals, so storage away from direct sunlight helps maintain appearance.
