Vegan Hyaluronic Acid (HA) Powder also known as Sodium hyaluronate CAS: 9067-32-7 Molecular Weight: 800KD~1,500 KD （HMWHA) High Purity (>99%), White powder, No odor, Soluble in water. Shelf-life up to 3 years if stored protected from humidity and microbial contamination. Question 1: Which Size HA is Better for you? HA products usually divided into different sizes: high molecular weight hyaluronic acid (HMWHA, 800-1500KD), and low molecular weight fragmental hyaluronic acid (LMWHA, <50KD), made from HMWHA digestion. The main difference is that LMWHA is faster to penetrate the skin, however, HMWHA still can be absorbed but slower after it's broken down by our skin microenvironment, which means its effect can last longer compared to LMWHA. HMWHA is actually better in moisturizing since it can form a film on the skin which protects it from losing water. Question 2: What Vegan HA means? Hyaluronic acid is a natural polysaccharide (large sugar molecule) and can come from different sources. The two main sources are biofermentation (made by bacteria) and rooster combs, which contain about 15 times as much hyaluronic acid as human skin. Vegan HA means it's made from biofermentation. Question 3: How to dissolve HMWHA ? HMWHA needs vigorous stir to be dissolved in water and will form a gel (LMWHA won't). It's better to disperse it in glycerin first and then add to the warm water with a hand mixer. HMWHA is typically used at 0.1-2% (while LMWHA can used at up to 10%). At the point no additional hyaluronic acid can be added as there is no water left f or it to be dissolved in (additional hyaluronic acid would only form lumps).
