Reviews Summary
Customers say this serum is deeply hydrating and absorbs quickly without stickiness or greasiness. They appreciate the lightweight texture that leaves skin feeling soft, smooth, and plump. Many mention using it on damp skin after cleansing as a first step in their routine. Users find it works well under makeup and other skincare products without pilling. Common feedback includes praise for the affordable price point and long-lasting formula, with many becoming repeat purchasers. Some note the small bottle size, though most appreciate that only a small amount is needed per application.

    Forever a staple

    No matter how many hydrating serums I try, I will always love this simple staple. I find myself adding it to my routine even when there is plenty of hydration going on, because I know it will only boost the efficacy and duration of whatever else I use.

    Hyaluronic Acid Serum

    I'm not really sure what this is supposed to do? I do know that it does not hydrate my skin.
