What Is Hydrolyzed Cornus Walteri Leaf Extract?
Hydrolyzed Cornus Walteri Leaf Extract comes from the leaves of Cornus walteri, a dogwood tree native to East Asia. The leaves are rich in natural sugars, polyphenols and small proteins that are valued for skin care. To make the ingredient, the raw leaf extract is treated with water, enzymes or a mild acid in a process called hydrolysis. This breaks the larger plant molecules into smaller pieces that can sink into the skin more easily and remain stable in a cream or lotion. Interest in Cornus walteri grew with the rise of Korean beauty products that favored gentle, plant based actives. Today the hydrolyzed extract shows up in lightweight serums, hydrating toners, sheet masks, anti aging creams, after sun gels and even some scalp treatments where calm moisture is needed.
Hydrolyzed Cornus Walteri Leaf Extract’s Cosmetic Benefits/Uses
Its main job in a formula is skin conditioning, meaning it helps the skin feel soft, smooth and well hydrated. The smaller molecules formed during hydrolysis can bind water and create a comfortable film on the surface, which supports the skin’s barrier and gives an instant silky touch. Over time this can make the complexion look healthier and more even.
