[n.m.] The concept of molecular weight is used to measure a molecule’s size. High molecular weight is when a molecule weighs more than 1,000 kDa (kiloDalton). Low molecular weight is between 5 and 50 kDa.
The larger a molecule, the longer it stays on the skin’s surface. Smaller molecules manage to slip between the intercellular spaces to reach the lower layers of the epidermis.
The hyaluronic acid used in formulating myBlend products is composed of both high and low molecular weights. The high weight moisturises the skin’s surface while forming a protective film to prevent drying. The low weight is absorbed, meaning it can reinforce hydration in the lower layers of the skin.
