Improve skin texture
Take the most common polydimethylsiloxane as an example, it can increase the smooth and delicate feeling of the skin without any greasy and residual feeling. Especially compared to some moisturizing products such as Vaseline, silicone oil, which also has moisturizing effect, is more refreshing and comfortable to use in summer, with good skin feel. Therefore, we know that silicone oil is often used in sunscreen to reduce the sticky feeling of various sunscreen agents.

Moisture
Some smaller molecules of silicone oil can penetrate the skin, forming a protective film that locks in moisture and keeps the skin moist.

Moisturizing, hair care and hair brightening
Silicone oil can deposit on hair, making the hair cuticle smoother, especially for damaged areas of the outermost hair cuticle. Using silicone oil shampoo and conditioner can make hair smoother, softer, reduce tangling, and facilitate combing.
Hair care: After the hair cuticle is covered with a layer of silicone oil, it can reduce friction, and a large part of the damage to hair generally comes from friction between hair strands.
Shining hair: Silicone oil deposits on the hair, forming a protective film on the surface of the hair, making the hair surface smoother and allowing more specular reflection of light, resulting in brighter hair.
