Hyaluronic acid (HA) is one of the simplest, but critically important polymers for the body. It is a highly hydrophilic substance that can bind 1000 times its weight in water. HA is naturally present in the skin and is not prone to cause unwanted reactions. In preparations for improving skin quality, HA is used to hydrate the dermis, but depending on its concentration, molecular weight and some other properties, it can have a different effect.
