To reduce these complexion irregularities over time, effective depigmenting active ingredients work on the melanogenesis chain by interrupting either the synthesis or the transfer of pigments to surface keratinocytes.\u003c\/p\u003e\n\u003cp\u003eCos De Baha's TN Serum relies on a synergy of two depigmenting active ingredients with complementary mechanisms: 5% tranexamic acid, which inhibits plasmin-mediated keratinocyte-melanocyte interactions responsible for pigment stimulation, and 5% niacinamide, which acts downstream by blocking the transfer of melanosomes to the cell surface. These two distinct mechanisms mutually reinforce each other. The formula is complemented by sodium hyaluronate and betaine for moisturizing comfort, and plant extracts for a certified natural index of 78% (N.O.I.P 78%).\u003c\/p\u003e\n\u003cp\u003eApply 2 to 3 drops to the face and neck after cleansing and toning, morning and evening. Gently pat until fully absorbed, before day or night cream. Tranexamic acid is not photosensitizing—this serum can be used without particular restrictions in the morning under SPF 50+ sun protection, which is highly recommended to optimize depigmenting results.\u003c\/p\u003e\n\u003cp\u003eThe formula is well tolerated by sensitive and reactive skin. No chemical exfoliation—no risk of acid irritation. 5% niacinamide may cause slight transient redness during the first uses on skin very reactive to this compound; this effect is temporary and generally disappears after 2 to 4 days of continuous use.\u003c\/p\u003e\n\u003cp\u003eIn the routine, this serum is integrated at the serum step after toner, before cream. It can be combined with a hydrating serum (pure HA) applied beforehand, or with TT Serum (TXA 10%) for a more intensive depigmenting action on stubborn hyperpigmentation. Perceptible improvement in complexion generally observed within 4 to 6 weeks of regular use.\u003c\/p\u003e","brand":"Cos De Baha","offers":[{"title":"Default Title","offer_id":53898331717969,"sku":"PD-0477","price":16.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1032\/7094\/1009\/files\/612m3zzpfWL._AC_SL1500.jpg?v=1779828023","url":"https:\/\/paradermia.com\/en\/products\/cos-de-baha-tn-serum-tranexamique-niacinamide-pd-0477","provider":"Paradermia","version":"1.0","type":"link"}
