Modern sex dolls have evolved remarkably, incorporating features that mimic human appearance and behavior with astonishing accuracy. One of the most significant advances is the use of high-quality silicone and TPE (thermoplastic elastomer), materials that replicate the softness, elasticity, and warmth of human skin. These materials allow for a lifelike texture that enhances the overall experience. Realistic facial features, including detailed eyes, lips, and even subtle facial expressions, further contribute to their authenticity. Some dolls are designed with movable jaws and blinking eyes, adding a layer of realism during interactions.

Another notable feature is the incorporation of flexible joints and articulated skeletons, allowing the doll to assume natural poses and positions. The incorporation of body heat and heating systems can simulate a real body temperature, providing a warm touch sensation. Additionally, advanced dolls often include features such as realistic hair, detailed fingernails, and even body tattoos for increased authenticity. Some models now feature customizable or interchangeable parts, such as different hair styles or breast sizes, allowing users to personalize their experience. Overall, the combination of these features creates an experience that approaches the sensation of interacting with a real person, making modern sex dolls a highly realistic and immersive option for users.
