At 20% that interception reaches a wider share of the pigment in production, so marks fade from the top layer down rather than being bleached out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhere a breakout has healed but the mark has not, tranexamic acid goes to work:\u003c\/strong\u003e Tranexamic acid interrupts the inflammatory signalling that keeps pigment-producing cells switched on long after the spot itself has cleared. It is the ingredient in here aimed squarely at post-acne marks rather than at general dullness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOn the oxidative side of pigment formation, glutathione is the considered addition:\u003c\/strong\u003e Glutathione acts on the free-radical reactions that keep melanin production running, which is a different point of entry from either the transfer step or the inflammatory one. Most of its established brightening research comes from oral and intravenous use, and topical study is newer and still building, which is the genuinely interesting part of finding it here.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA Centella complex takes the edge off a high dose:\u003c\/strong\u003e Asiaticoside and madecassic acid calm irritation and reinforce the barrier, with allantoin, purslane and peony root doing the same quiet job behind them.

Niacinamide starts working on tone in the low single digits, so 20% is a deliberate step up rather than a number on a label. It is also not left to work alone: tranexamic acid is in there for post-acne marks specifically, and a Centella complex is in there so the concentration stays wearable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does niacinamide actually shrink your pores?\u003c\/strong\u003e\u003cbr\u003eA: No, and nothing applied to the skin does. Pore size is set largely by genetics and by how much oil is passing through, and niacinamide moderates that flow while firming the skin immediately around the opening, which is what makes pores read as smaller. At 20% that effect is easier to see than at low single-digit doses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this alongside my other actives and sunscreen?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Niacinamide is unusually cooperative, so this serum shares a routine with acids, retinoids and Vitamin C without conflict, whether in one session or split between morning and evening. It goes on after cleansing and any toner or essence, under moisturiser, with sunscreen as the final step in the morning, and that daily sunscreen matters more than ever while you are working on dark spots, because UV puts back what the serum takes off.\u003c\/p\u003e\n\u003cp\u003eThe number on the bottle is the least interesting thing about this serum; half the ingredient list is there so that the other half can be tolerated.\u003c\/p\u003e\n\u003cdiv class=\"sn-explore-more\"\u003e\n\u003cp\u003eExplore the \u003ca class=\"sn-ilink\" href=\"\/collections\/niacinamide\"\u003eniacinamide collection\u003c\/a\u003e for complementary treatments, or the \u003ca class=\"sn-ilink\" href=\"\/collections\/pigmentation\"\u003epigmentation collection\u003c\/a\u003e for a complete dark-spot routine.\u003c\/p\u003e\n\u003cul\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\/pigmentation\"\u003ePigmentation\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/jumiso\"\u003eMore from Jumiso\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n","brand":"Jumiso","offers":[{"title":"Default Title","offer_id":55164408725838,"sku":"HLSS01-NA20","price":17.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/5057\/0062\/files\/HLSS01-NA20.png?v=1778671451"}],"url":"https:\/\/skin-nomad.fr\/collections\/jumiso.oembed","provider":"Skin-Nomad","version":"1.0","type":"link"}
