How we score →Yay
5 experts · Moderate agreementWhat the gurus are saying
Sensitive and dry skin is where this serum earns its praise, since its 10% lactic acid is described as gentle and its texture as nourishing rather than heavy. However, one dissenting take says that much lactic acid makes daily use hard, which could leave the peptides short on steady use. Some have mentioned using it a few times a week in place of a retinoid.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.
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.
