In ingredient lists of various cosmetics, components containing the terms 'silane' or 'siloxane' are very common; these are commonly referred to as 'silicone oil.' As a widely used material in the beauty industry, silicone oil is applied extensively in skincare, makeup, and hair care products due to its excellent properties, yet it also raises questions among many consumers.

The practical benefits of silicone oil are highly recognized within the industry. In skincare, it can improve the texture of products, providing a refreshing and smooth feel, and when added to sunscreens, it can reduce stickiness. Low-molecular-weight silicone oil can form a protective layer on the skin, locking in moisture, and it feels lighter than ingredients like petrolatum, especially in summer. In hair care, silicone oil deposits on hair strands, smoothing damaged cuticles, reducing friction, preventing tangling, and enhancing shine, making it a 'savior' for dry and damaged hair. Additionally, silicone oil is highly stable, heat-resistant, UV-protective, and gentle on the skin without causing irritation.

As for the popular concern that 'silicone oil clogs pores,' there is currently no scientific evidence to support this. Silicone oil is a large molecule that only stays on the surface of the skin, is not absorbed, does not block pores, and does not directly cause hair loss. The claim that 'silicone-free products are better' is also inaccurate; there is no inherent superiority between silicone-containing and silicone-free shampoos. People with oily hair may prefer silicone-free options to maintain volume, while those with dry or damaged hair can benefit from silicone-containing products for nourishment and repair.

Common types like dimethicone, cyclomethicone, and phenyl silicone oil each have their advantages and suit different cosmetic product needs. Industry professionals advise that consumers do not blindly avoid silicone oil; choosing products according to individual skin and hair types allows cosmetics to achieve their optimal effects.
