It also gives a nice silky feeling when you apply the product to the skin and hair. It leaves a thin film that protects the skin after evaporation.

Cyclopentasiloxane is chemically neutral, meaning it doesn’t react with other components.

Squalane is a more stable equivalent of Squalene. It is a very important component of our skin. It’s a major part of natural sebum that forms a protection barrier on the skin's surface. If the barrier isn’t strong enough, your skin will become more sensitive. Squalane helps to keep skin hydrated, protects it from the negative impact of the environment, lowers irritation, stimulates regeneration, and removes dryness. It is accepted by our skin very well and will not cause allergic reactions.
