Paula's Choice CLINICAL Discoloration Repair Face Serum is formulated with tranexamic acid as its key active ingredient, targeting stubborn dark spots, post-acne marks, and sun damage. This fragrance-free facial serum is designed to support a more even skin tone over time, working on discoloration without relying on harsh bleaching agents. The lightweight, non-greasy texture absorbs quickly into the skin, making it suitable for daily use under moisturizer or sunscreen. The serum is part of a clinical-strength line that prioritizes gentle yet effective ingredients; as with all Paula's Choice products, it is free from fragrance, parabens, and drying alcohols. Suitable for a range of skin types, including sensitive and acne-prone skin, it focuses specifically on areas of uneven pigmentation rather than overall brightening. The one-fluid-ounce bottle delivers a concentrated dose of active ingredients, encouraging consistent application as part of a morning or evening routine. Users with persistent unevenness from sun exposure, hormonal changes, or past breakouts may find this serum a purposeful addition to their regimen. Its neutral formulation leaves no sticky residue and works well in combination with other skincare products such as vitamin C, retinoids, or SPF. By targeting the underlying mechanisms of discoloration rather than just surface symptoms, this serum provides a targeted approach to fading hyperpigmentation while maintaining skin barrier health. Regular use, combined with sun protection, may help reduce the visibility of stubborn marks and promote a more unified complexion over several weeks.
