Skin cracks on sex dolls are often caused by dryness, exposure to sunlight, or material aging. To prevent cracks, keep the doll’s skin well hydrated by regularly applying a suitable moisturizer or talcum powder. Store the doll in a cool, shaded environment and avoid prolonged direct sunlight exposure. When cleaning or handling, be gentle to avoid undue stress on the surface. If cracks do appear, small fissures can sometimes be repaired using specialized silicone or TPE repair kits. Clean the cracked area thoroughly, then apply the repair compound according to instructions, smoothing it out to blend with the surrounding surface. For larger or more severe cracks, professional restoration services are recommended to ensure proper repair and color matching. Preventative care, including regular hydration and careful storage, is key to avoiding cracks. Addressing minor cracks early can often restore the doll’s appearance and prolong its usability, maintaining a realistic and smooth skin surface.
