This serum is formulated to address the appearance of post-acne marks and uneven skin tone. The key active ingredients include Vitamin C, known for its brightening properties, and Niacinamide, which helps support the skin barrier and improve the look of discoloration. Antioxidants in the formula work to protect the skin from environmental stressors that can contribute to dullness. The lightweight gel texture is designed to absorb quickly without leaving a sticky or heavy residue, making it suitable for various skin types including combination and oily skin. This product is intended for use on the face as part of a daily skincare routine, targeting the visible signs left by blemishes. The 1.69 fl. oz. bottle provides a practical amount for regular application. It is important to note that individual results depend on consistent use over time, as skincare effects vary by person. This Korean skincare item focuses on a gentle approach, avoiding harsh components that might irritate sensitive skin. The serum can be used after cleansing and toning, and before moisturizing. Its formulation aims to deliver a balanced blend of active ingredients without excessive fragrance or oil. This product does not claim to erase scars or prevent future breakouts, but rather to support the skin’s natural recovery process by providing targeted nourishment. As with any skincare product, a patch test is recommended before full application to ensure compatibility.
