Why we use it

Peptides can be fragile and are prone to degrading over time. By encapsulating these active ingredients, we keep them stable and ensure they reach their intended destination. Polyvinyl alcohol (PVA) makes up the outer layer of these microscopic capsules. The PVA dissolves when it reaches its intended destination, freeing the active peptides inside.
