Preserving the face makeup of your sex doll is crucial for maintaining its lifelike appearance. Start by handling your doll with clean hands to prevent transferring oils or dirt onto the makeup. When cleaning the face, use a soft, damp cloth and mild, non-abrasive cleansers, avoiding alcohol-based products that can strip the makeup. If you need to touch up or add makeup, use high-quality, compatible cosmetic products designed for silicone or TPE surfaces. Always perform patch tests on a small area first to ensure compatibility. To prevent smudging or wearing off, avoid excessive touching or rubbing of the face, especially around painted areas like lips and eyes. When not in use, store your doll in a position that minimizes contact with rough surfaces or objects that could cause scratches or smudges. Applying a light coat of setting spray designed for delicate makeup can also help lock in the design. Regularly inspecting the makeup and performing touch-ups as needed will keep your doll looking fresh and realistic over time.
