Cos De Baha — Tranexamic Acid TT Serum 10% 30ml

The TT Serum is the most complete depigmenting formula in the Cos De Baha range. The 10% TXA doubles the concentration of TN (5%), amplifying plasmin inhibition, which is at the origin of pigment stimulation. At this concentration, we exceed the published clinical studies on topical TXA (generally 2 to 5%) – incremental efficacy is biologically expected but remains to be evaluated based on individual tolerance, such as tolerance. Niacinamide (2%) maintains its role as a melanosome transfer blocker. The multi-active architecture is enriched with several complementary active ingredients: glutathione is an intracellular antioxidant which, when applied topically, contributes to skin tone uniformity by inhibiting oxidative melanogenesis (rather targeting pheomelanin). EGCG (Epigallocatechin Gallate) is the main polyphenol in green tea, a powerful antioxidant documented for its photoprotective and anti-tyrosinase action. Madecassoside (isolated from Centella asiatica) contributes to the recovery of the skin barrier, often weakened by reactive hyperpigmentation. Tropolone is a natural tyrosinase inhibitor – a distinct mechanism from TXA and niacinamide, providing a third pathway of action. The Cetearyl Alcohol present is a fatty alcohol (non-irritating – not to be confused with denatured alcohol). Fragrance-free formula, generally well-tolerated. Reserved for skin that has already used TN without sufficient results or for established hyperpigmentation. Pregnancy: Cosmetic topical TXA has no formal contraindication but limited data, consult as a precaution.
