Hyaluronic Acid ●
TL;DR. This ingredient is a humectant and skin-conditioning polymer that binds water and improves the feel of hydration on skin and hair. It also helps give serums and gels a smooth, cushiony texture.
What does Hyaluronic Acid do in a cosmetic formula?
This ingredient is a humectant and skin-conditioning polymer that binds water and improves the feel of hydration on skin and hair. It also helps give serums and gels a smooth, cushiony texture.
Is Hyaluronic Acid clean?
From a clean-beauty perspective, it is generally well tolerated, non-sensitizing for most users, and not a common restricted-list concern. The main quality points are purity, microbial control, and responsible preservation of the finished formula.
Is Hyaluronic Acid sustainable?
This material is commonly made by controlled fermentation rather than animal sourcing, which gives it a more traceable supply profile. It is water soluble and biodegradable, with low concern for environmental persistence.
Is Hyaluronic Acid COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when made through accepted fermentation processes with compliant inputs. Its profile fits Green Chemistry well because fermentation can use renewable feedstocks, water-based processing, and mild production conditions.
How does Hyaluronic Acid work chemically?
The molecule is a linear glycosaminoglycan built from repeating sugar-acid disaccharide units, with molecular weights ranging from a few kilodaltons to well over 1 million daltons depending on grade. Typical use levels are about 0.01% to 0.5%, and performance depends on molecular weight, pH, electrolyte load, and preservation because water-rich formulas need robust microbial protection.
