You might know this as 'mini' or 'ultra low-molecular weight' hyaluronic acid. The small molecule size means it is able to travel deeper in the skin.
According to studies, low molecular-weight hyaluronic acid can:
One study from 2011 found ultra-low weight HA to show pro-inflammatory properties. Another study from 2022 found it to downregulate UV-B induced inflammation.
Hydrolysis is a process of changing a molecule using water or enzymes.
