This serum contains 10% tranexamic acid, a concentration commonly used in skincare formulations aimed at addressing uneven skin tone. Tranexamic acid is known for its ability to inhibit melanin production, making it a targeted ingredient for reducing the appearance of dark spots, melasma, and post-inflammatory hyperpigmentation. The formula also includes hyaluronic acid, which provides hydration to support skin barrier function and improve overall texture without adding heaviness.

Suitable for most skin types, including sensitive and acne-prone skin, this serum is designed to be used as part of a daily skincare routine. Its lightweight, water-based texture absorbs quickly and layers well under moisturizers or sunscreens. The product is free from common irritants such as artificial fragrances, parabens, and sulfates, aligning with the gentle formulation principles often associated with Korean skincare.

Regular application may help gradually fade existing discoloration while preventing new spots from forming, though individual results can vary based on skin condition and consistency of use. It is recommended to apply a few drops to clean, dry skin, focusing on areas of concern, and to follow with sunscreen during the day to protect against UV-induced pigmentation. The 1.17 fl oz bottle offers a practical amount for sustained use, typically lasting several weeks with daily application. This serum is a practical option for those seeking a non-irritating, ingredient-focused approach to managing hyperpigmentation without resorting to harsh treatments.
