A competent hydration serum, but the headline hype is doing more work than the formula.

READ MORE

The efficacy score is driven mainly by a solid humectant base (glycerin, propanediol, sodium hyaluronate, crosspolymer hyaluronate, hydrolyzed hyaluronic acid) plus supportive soothing/barrier ingredients like panthenol, centella, and niacinamide; however, niacinamide is not especially high enough to promise strong brightening, and several botanical/ferment/seaweed ingredients are more supportive than truly transformative. There is no obvious pH-sensitive treatment active here, so this is best judged as a well-built hydration and soothing serum rather than a high-impact treatment formula.
