What is Hyaluronic Acid?
As the molecular weight of HA is relatively high, its penetration in the skin is very problematic when topically applied, and HA-based creams, lotions and serums will only moisturize the superficial layers of the skin. On the contrary, when orally administered, 90% of the ingested HA is absorbed into the body and migrate into connective tissues, such as skin (6-8). HA will then increase water in the skin and stimulates collagen, HA and proteoglycan synthesis as demonstrated in several clinical studies. (9-13) As the result, HA will provide a durable and deep skin hydration with a plumping effect.
