Cos De BAHA Tranexamic Acid 5% Serum is a skincare formulation designed to address dark spots, uneven skin tone, and melasma. This 30 ml (1 fl oz) product combines 5% tranexamic acid with 5% niacinamide, hyaluronic acid, and aloe vera as key ingredients. Tranexamic acid is known for its ability to inhibit melanin production, which can help reduce the appearance of hyperpigmentation over time. Niacinamide supports skin barrier function and further contributes to evening out skin tone, while hyaluronic acid provides hydration to maintain skin moisture. Aloe vera is included for its soothing properties, making the serum suitable for various skin types, including sensitive skin.

The serum has a lightweight, water-based texture that absorbs quickly without leaving a greasy residue. It is free from harsh chemicals such as parabens, sulfates, and artificial fragrances, aligning with a focus on gentle, natural-derived ingredients. The formula is non-comedogenic, meaning it is unlikely to clog pores, which may benefit those prone to acne or breakouts. Regular use as part of a skincare routine can support a more balanced complexion, particularly for individuals dealing with sun damage, post-inflammatory hyperpigmentation, or discoloration from hormonal changes.

This product is priced affordably compared to many clinical-grade serums, offering a practical option for those seeking targeted treatment without high costs. It is best applied after cleansing and before moisturizer, with sunscreen recommended during daytime use to protect the skin from further UV-induced discoloration. The serum is manufactured in South Korea, where strict quality standards apply to cosmetic production. Suitable for daily use, it caters to users looking for a straightforward, ingredient-focused solution for pigment-related concerns.
