The longevity of a premium sex doll largely depends on how well it is cared for, the materials used in its construction, and how frequently it is used. High-quality sex dolls made from medical-grade silicone or TPE (thermoplastic elastomer) can last for many years, often 5-10 years or longer with proper maintenance. To maximize the lifespan of a doll, it’s important to regularly clean and dry it after each use. Talcum powder or cornstarch is often recommended to keep the doll’s skin feeling soft and prevent it from becoming sticky. Storing the doll in a cool, dry place, away from direct sunlight and heat sources, also helps prevent material degradation. Many premium sex dolls are equipped with posable joints, which may wear out over time if not handled properly. Proper storage and gentle handling can help maintain these features for longer periods. Some dolls also come with removable parts, such as heads or genital areas, which can be replaced if they wear out. In general, with responsible care, premium sex dolls can provide years of use and maintain their realistic feel and appearance for a long time.
