I’ve been using this serum at night for about two weeks, and I’m really impressed with how calm and hydrated my skin feels the next morning—no irritation at all. The ectoin makes a noticeable difference in soothing redness compared to other niacinamide serums I’ve tried. It absorbs quickly without any sticky residue, which is a huge plus for my oily skin.
