The realism of full-function sex dolls has improved dramatically over recent years, making them increasingly lifelike in appearance and feel. High-quality materials like silicone or TPE replicate the softness, warmth, and texture of human skin, complete with detailed features such as realistic eyes, hair, and facial expressions. Anatomical accuracy in body proportions and features further enhances authenticity.

Movable joints and internal skeletons allow for natural positioning and posing, mimicking human movement and postures. Some advanced models incorporate heating systems, tactile sensors, and even customizable scents, adding to the realistic experience. The incorporation of AI and interactive features is gradually bridging the gap between physical realism and emotional engagement.

Despite these advancements, certain aspects—such as genuine emotional response or complex facial expressions—still have limitations compared to real humans. However, for many users, the current level of realism is sufficient to provide a convincing and satisfying experience. As technology continues to evolve, the gap between artificial and real will likely narrow further, making full-function sex dolls even more indistinguishable from real companions.
