Authentic silicone dolls are normal and harmless, but they must not be eaten. Because silicone dolls need to be made of silicone oil when their skin is more realistic in the production process, silicone dolls will produce oil. If you find oil stains, you can clean them directly or add shower gel. After washing and drying, you can take pictures with talcum powder.
Silicone oil has been widely used in various industries, and it is one of the non-toxic and tasteless products in silicone. It comes from a chemical substance that does not conflict with any substance. After draining, it can be washed directly with water, and it is no problem to put cleaning agent. If the oil keeps coming out, just wash it frequently. Silicone dolls need regular maintenance and more talcum powder, so as not to affect their performance. When buying, I suggest that you must choose a regular manufacturer and don't lose money for the sake of cheapness.
