Silicone oil is a type of commonly used synthetic material with stable chemical properties, widely applied in skincare products, shampoos, and medical devices. It can form a breathable film on the skin's surface, locking in moisture without clogging pores—this characteristic has been verified by cosmetics regulatory authorities worldwide.
Claims that "silicone oil is harmful" lack scientific basis. Studies show that cosmetic-grade silicone oil has a large molecular weight, unable to penetrate the skin into the bloodstream, let alone cause hair loss or poisoning. The notion that "silicone-free products are safer" is actually a marketing tactic by businesses. Consumers need not pay a premium for this. Choosing regular products and rationally  ingredients is the wise approach.
