CIR Rating [ A ]

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.

Avocado oil is a natural ingredient with an excellent rejuvenating and moisturizing effect. It's so effective because it contains a lot of squalene - a very strong chemical that protects the skin and helps to keep it hydrated. It's also a nice antioxidant that helps to slower aging. Avocado oil also contains different vitamins (A, B, E), lecithin, and beta-carotene.
