8 experts · Strong agreementWhat the gurus are saying
This water-light essence-serum hydrates and plumps the skin with six peptides that target fine lines, elasticity, and radiance, and it layers beautifully under other actives including retinoids. Most gurus praise its texture, affordability, and multitasking benefits, though one expert notes it works best as a booster within a full routine rather than as a standalone active. If you have sensitive skin or struggle with irritation, the niacinamide and calming peptides may help, but patch-test first since sensitivities to niacinamide do occur.
