Exposure to ultraviolet (UV) rays can cause significant damage to the materials of sex dolls, leading to fading, cracking, or deterioration over time. To prevent this, always store your doll in a shaded, indoor environment away from direct sunlight. If the doll must be outside temporarily, cover it with a UV-protective cloth or tarp to shield it from harmful rays. When cleaning or handling the doll outdoors, do so in shaded areas and use UV-safe cleaning products. Applying a UV-protective spray or coating designed for silicone or TPE materials can add an extra layer of defense against sun damage. Regularly inspect the doll for signs of fading or cracking, and address issues promptly. Avoid leaving the doll in parked cars or windowsills where sunlight can intensify. Proper storage and protective measures will preserve the doll’s color, texture, and structural integrity, ensuring it remains realistic and durable for years to come.
