Hyaluronic Acid +B5 Serum 1

Sodium Hyaluronate is the sodium salt of Hyaluronic acid and has a much smaller molecular size than Hyaluronic acid, causing it to easily penetrate the skin's surface, and is able to retain a relatively large amount of water — up to 1,000 its own weight. This means it can penetrate to lower layers of the skin, attract and retain water, and promote nutrient absorption. Sodium Hyaluronate is produced biotechnologically through microbial fermentation of yeast extract. It is rated a 1 out of 10 by EWG’s Skin Deep safety database, with 1 being the safest rating that they give.

When different molecular weights are used simultaneously in the same formulation, it can have synergetic effects, to activate global moisturization throughout the layers of the skin and less trans-epidermal water loss.
