Ingredient review
Acetyl Rhubarb Root Extract
INCI: Acetyl Rheum Rhaponticum Root Extract
A gentle, antioxidant-rich extract that may help calm skin and fight environmental stress, but research is still early.
In plain English
This is a processed version of rhubarb root extract, modified to make it more stable and effective in skincare. Rhubarb root naturally contains compounds like anthraquinones and stilbenoids, which can help soothe irritation and protect skin from damage caused by pollution and UV rays. The 'acetyl' part means a small chemical group was added to improve how well the ingredient works in your product.
