I've personally struggled to find a niacinamide serum that delivers high potency without causing irritation or breakouts. After trying this serum with 20% niacinamide, along with TXA 1% and Glutathione, I noticed a remarkable difference. Its lightweight texture absorbs quickly and doesn't clog my pores, which is a game changer for my acne-prone skin. Consistency is key for me, and using this serum daily helped improve my skin tone and reduce redness without disrupting my skin barrier. Unlike other high-strength serums that made my skin sensitive, this formula feels gentle and soothing throughout the day. The addition of Glutathione provides antioxidant benefits, contributing to a brighter and more even complexion. If you’re cautious about potent active ingredients but want effective skincare, this serum strikes the perfect balance. It’s also great as part of a K-beauty routine, complementing other gentle products without causing irritation. For those with sensitive or acne-prone skin, this serum offers a reliable option to enjoy the benefits of niacinamide without compromise.
