Skin fading on sex dolls can diminish their realistic appearance over time, often caused by exposure to sunlight, harsh cleaning agents, or improper storage. To prevent fading, always keep your doll out of direct sunlight, especially during prolonged periods, as UV rays accelerate color degradation. Store the doll in a cool, dry place away from heat sources and fluorescent lighting, which can also contribute to fading. When cleaning, use gentle, pH-neutral products specifically formulated for doll materials, avoiding harsh chemicals or alcohol-based cleaners that can strip color. Regularly dust and clean the surface to prevent dirt buildup, which can affect the pigment. Applying a protective sealant or matte finish designed for silicone or TPE can provide an additional barrier against UV rays and environmental factors. If your doll has painted or dyed features, consider using a UV-blocking spray or coating to preserve the vibrancy of the skin tone. Proper handling, careful cleaning, and responsible storage are key to maintaining the doll’s original appearance and ensuring its colors stay vivid for years to come.
