Hyaluronic acid (HA) is a naturally occurring substance in our skin that decreases as we age. It holds more than 1000x its weight in water and is a humectant, which means it draws water from its surroundings and holds on to it. This serum contains pure hyaluronic acid at a 1% concentration, with both high and low molecular weight. Hydrated in distilled Maine spring water, with sweetgrass and cucumber hydrosol, plus the extracts of gingko biloba, Gotu kola, Korean ginseng, and sea kelp bio-ferment.

1oz treatment pump, cobalt blue glass bottle.
