Hydrolyzed Yeast Extract

INCI Hydrolyzed Yeast Extract

Yeast-Derived Conditioning Active Botanicals & Antioxidants

What it is & what it does

Hydrolyzed Yeast Extract is a yeast-derived conditioning ingredient that can supply peptides, amino acids and other soluble components.
WHAT IT IS: Hydrolyzed Yeast Extract is a yeast-derived cosmetic mixture of soluble components created through controlled breakdown of yeast material.

WHAT THE SCIENCE SUPPORTS: Depending on the raw material it can provide amino acids, peptides and other conditioning compounds. Experimental and supplier studies on yeast-derived complexes explore hydration and antioxidant-related functions, but activity cannot be assumed to be identical across every hydrolyzed extract.

IN A SKINCARE ROUTINE: The supplier specification and the finished formula determine which skin-conditioning claims are justified. Claims for one ingredient should not be presented as a proven result for every finished product.

Usage & cautions

Yeast-derived products can trigger individual sensitivities; stop if a rash develops.
Information approach Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
