Experts split on the Centella claim, since the formula is mostly water and Centella sits far down the ingredient list, which some find overstated. Others praise it as watery, lightweight and quick to sink in, a pat-on step that layers well with drying acne treatments and feels calming for sensitive skin. Its poly glutamic acid forms a soothing film that helps cut water loss without feeling heavy.
