How we score →Yay
5 experts · Moderate agreementWhat the gurus are saying
Its light, runny texture and quick absorption keep coming up, and so does its copper peptide at the center. Most takes praise the hydration and non-greasy finish, and some say it can stand in for vitamin C for anyone who can't tolerate that. The mixed takes were less enthusiastic, and they warned that more than about a third of a dropper led to peeling, so thin layers tend to work best.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
