How we score →Score withheld
2 of the 3 takes here are sponsored by the brand. That leaves a single independent take, which is not enough to verify a score, so we are holding it back rather than publishing a number built on paid reviews. The takes are below, each labeled.
What the gurus are saying
This serum earns consistent praise for pairing a high concentration of vitamin C with centella asiatica, a combination experts call a powerhouse for collagen and anti-aging. Mad About Skin repeatedly highlights that it works quickly without triggering redness or sensitivity, comes in a lightweight watery formula that keeps skin breathable, and delivers results at an accessible price point. One expert who tried it found the nourishing base pleasant and plans to report back on longer-term effects.
