At 6% Tranexamic Acid, 10% Niacinamide, and stabilised Retinal, each active is present at a concentration where the peer-reviewed research for its mechanism demonstrates meaningful results. PURITO SEOUL is a Seoul-based brand founded in 2017.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e6% Tranexamic Acid for upstream melanin production inhibition:\u003c\/strong\u003e Disrupts the plasmin-mediated keratinocyte-melanocyte signalling pathway that instructs melanin to be produced in response to UV and inflammatory stimuli, addressing pigmentation at the production-signalling stage before melanin is synthesised.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10% Niacinamide for melanosome transfer inhibition:\u003c\/strong\u003e At 10%, inhibits the transfer of melanin-containing melanosomes from melanocytes to keratinocytes — addressing the distribution of already-produced melanin.

Niacinamide blocks the transfer of already-produced melanin to keratinocytes. Retinal accelerates surface cell turnover, increasing the rate at which melanin-containing pigmented cells are replaced by new, unpigmented cells. Each addresses a different stage of the melanin cycle — production, distribution, and removal — producing truly non-overlapping, complementary brightening activity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I layer this with the Azelaic Acid 10 Kojic Tea Tree Serum?\u003c\/strong\u003e\u003cbr\u003eA: Apply them on alternating evenings rather than the same evening to avoid over-stimulating the skin. Both are evening actives with acid content; using them together daily can compound the potential for barrier disruption.\u003c\/p\u003e\n\u003cp\u003eThe evening serum for skin that has tried brightening serums that address one stage of the problem and found one stage insufficient for what it is dealing with.\u003c\/p\u003e\n\u003cdiv class=\"sn-explore-more\"\u003e\n\u003cp\u003eExplore the \u003ca class=\"sn-ilink\" href=\"\/collections\/pigmentation\"\u003epigmentation collection\u003c\/a\u003e for daytime brightening serums to pair with this evening treatment.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/pigmentation\"\u003ePigmentation\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/niacinamide\"\u003eNiacinamide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/purito-seoul\"\u003eMore from PURITO SEOUL\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PURITO SEOUL","offers":[{"title":"Default Title","offer_id":59240835187022,"sku":"PRS20-S","price":23.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/5057\/0062\/files\/PRS20-S.png?v=1779229178","url":"https:\/\/skin-nomad.fr\/products\/purito-seoul-txa-6-niacinamide-10-retinal-serum","provider":"Skin-Nomad","version":"1.0","type":"link"}
