Cos De BAHA Tranexamic Acid 10 Serum (TT) 30ml30ml

Key Ingredients

• Tranexamic Acid (marketed at 10%): the second-listed ingredient (right after Centella Asiatica Extract), consistent with a meaningful concentration; used in skincare for supporting a more even-looking skin tone and addressing the appearance of hyperpigmentation and dark spots. The 10% figure is the brand's stated concentration; MedEasy could not independently lab-verify this exact percentage, as INCI order reflects descending concentration but not exact figures
• Centella Asiatica Extract: the first-listed ingredient, included for its soothing, skin-barrier-supportive reputation
• Niacinamide, Allantoin, Panthenol: included for additional tone-support, soothing, and skin-conditioning benefits
• Glutathione, Epigallocatechin Gallate (EGCG): included as antioxidant-supportive ingredients
• Important note on emulsifiers: the formula contains Cetearyl Olivate, Sorbitan Olivate, and Cetearyl Alcohol, which some ingredient-analysis sources flag as potentially less suitable for those prone to seborrheic dermatitis or fungal-acne (malassezia) concerns -- worth noting for those with this specific skin sensitivity
