How we score →Yay
4 experts · Moderate agreementWhat the gurus are saying
Under that "100% pure" name, this thin, never-sticky serum also carries a stable vitamin C and Matrixyl peptides, and those extras are why the gurus keep reaching for it, even if they admit the add-ons may or may not do much. It spreads easily, doesn't pill under other products and feels especially welcome in colder months. The one gripe is a squeeze top, where a pump would be cleaner.
