Fisetin ●
TL;DR. It functions primarily as an antioxidant and skin-conditioning active in beauty products. It is used to support oxidative-stress, tone-evening, and photoaging-related claims rather than as a structural base ingredient.
What does Fisetin do in a cosmetic formula?
It functions primarily as an antioxidant and skin-conditioning active in beauty products. It is used to support oxidative-stress, tone-evening, and photoaging-related claims rather than as a structural base ingredient.
Is Fisetin clean?
It has no common clean-standard restricted-list profile and is generally viewed as a low-sensitization antioxidant when well purified. The main caveats are limited cosmetic use history, natural yellow color, and purity or residual-solvent control.
Is Fisetin sustainable?
It can be isolated from plant materials or made as a nature-identical compound, so its footprint depends on feedstock and extraction solvent choice. As a polyphenol, it is expected to be biodegradable rather than highly persistent, but extraction yield and solvent recovery matter.
Is Fisetin COSMOS-approved?
It may fit COSMOS-natural when sourced from permitted natural feedstocks and processed with approved extraction or purification methods, while fully synthetic versions would not align as well. From a Green Chemistry lens, it scores best with renewable sourcing, ethanol or water-based processing, and tight solvent recovery.
How does Fisetin work chemically?
The molecule is a small polyphenolic flavonol with multiple hydroxyl groups, giving it radical-scavenging and metal-interaction behavior but low water solubility. It is typically used at low active levels in serums or creams, and formulators often need solubilizers, encapsulation, or oil-dispersion strategies to manage crystallization and color shift.
