High-concentration niacinamide and Zinc PCA are two complementary active ingredients that address these two issues simultaneously.\u003c\/p\u003e\n\u003cp\u003eCos De Baha's NZ Serum is formulated with a high density of active ingredients: 20% niacinamide — one of the highest concentrations available in mainstream K-beauty — combined with 4% Zinc PCA. Niacinamide regulates sebum production, helps tighten the appearance of pores, strengthens the skin barrier, and supports skin tone uniformity. Zinc PCA (zinc-pyroglutamic acid complex) complements this sebosuppressive action through a distinct mechanism on the sebaceous glands. Caffeine provides a toning effect and helps refine the appearance of pores. Arbutin, in a secondary concentration, contributes to the gradual evening of skin tone.\u003c\/p\u003e\n\u003cp\u003eApply 1 to 2 drops to the face after cleansing and toning, morning and evening, before moisturizing cream. Gently pat until absorbed. The texture is fluid with a slight consistency — fast-drying, with no residual film. Can be used under makeup.\u003c\/p\u003e\n\u003cp\u003eImportant precaution: With 20% niacinamide, a phenomenon of transient redness and warmth (flush) is possible during the first applications on skin not accustomed to this concentration. This is a normal reaction related to the skin's metabolism of high-dose niacinamide, generally not painful and disappearing within 10 to 20 minutes. Prior patch testing (on the neck) is strongly recommended. This serum should not be applied simultaneously with a low-pH vitamin C serum (such as pure ascorbic acid) — alternate morning and evening.\u003c\/p\u003e\n\u003cp\u003eThis serum is ideal as a reference serum for combination to oily skin in a K-beauty routine. It can be combined in a routine with a hydrating serum (pure HA) as a base layer to compensate for the slightly drying sensation of the high concentration, and with SS Serum (2% BHA) on alternating evenings for complementary pore action and exfoliation.\u003c\/p\u003e","brand":"Cos De Baha","offers":[{"title":"Default Title","offer_id":53898332111185,"sku":"PD-0483","price":14.24,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1032\/7094\/1009\/files\/cos-de-baha-nz-serum-niacinamide-zinc-pca-pd-0483-1-hd.jpg?v=1788396172","url":"https:\/\/paradermia.com\/en\/products\/cos-de-baha-nz-serum-niacinamide-zinc-pca-pd-0483","provider":"Paradermia","version":"1.0","type":"link"}
