Safety and skin compatibility should guide every purchase. Look for materials that are non-porous and hygienic, such as medical-grade silicone or high-quality TPE, and confirm that the product is free from prohibited phthalates, heavy metals, and other skin irritants. Seek documentation or third-party testing that confirms low allergen content and skin-safe properties, especially if the doll will be used regularly or in direct skin contact. In Europe, look for compliance with chemical safety standards like REACH, and ask for any available dermatological testing results or certification notes. While not all sex dolls carry the same regulatory marks as medical devices, reputable sellers will provide material safety data sheets (MSDS) and care instructions. Verify maintenance guidance for cleaning agents and storage requirements, and ensure the manufacturer offers genuine support for repairs or parts. If the doll has interchangeable parts or sensitive joints, request guidance on compatible lubricants, cleaners, and replacement components. Emphasize long-term suitability: safe materials, proper cleaning routines, and stable storage conditions reduce risks and help maintain the product’s integrity and your peace of mind.
