Hyaluronic Acid (LMW) has many functions including holding moisture, contributing to mechanical resilience and suppleness of the skin and regulating immune and inflammatory responses. Sodium PCA is one of the major components of our skins’ natural moisturizing factor (NMF) and helps bind moisture to our skin cells. It also helps protect and reduce inflammation in our skin. Betaine helps tighten the skin and minimize pores, as well as having anti-inflammatory, anti-ageing and brightening properties. Allantoin stimulates skin cell regeneration and helps heal and protect sensitive skin while it soothes and softens.
