It is one of the most important components of our skin. It combines collagen and elastin fibers in the skin. It occurs as hygroscopic liquid with gel properties, which makes it a versatile and easily used carrier of other active substances.

The content of hyaluronic acid in the skin depends on age. Over 50% of its content in our body is located in the dermis. Its highest concentration is found in the skin of babies and with it decreases. This decrease is especially rapid passing 50 years of age. Also, due to UV radiation, hyaluronic acid is subject to photodegradation. Its ability to retain water leads to maintaining proper hydration of skin cells. Well-moisturized skin is better protected against damage and becomes more permeable for active substances.
