This Purito serum combines three active ingredients at specified concentrations in an original bi-phase format: 6% tranexamic acid for pigment inhibition, 10% niacinamide for skin tone uniformity and barrier strengthening, and 25 ppm retinal (retinaldehyde) for an encapsulated retinoid pathway.\u003c\/p\u003e\n\u003cp\u003eBi-phase with capsules format: shake the bottle 3 to 5 times before each use to disperse the encapsulated active ingredient capsules. Without this step, the active ingredients will sediment, and the applied dose will be uneven. The natural pink color of this serum is due to cyanocobalamin (vitamin B12) — it may fade slightly with light exposure, without affecting quality. The formula also includes a set of microbiome active ingredients: Lactococcus Ferment Lysate (probiotic lysate) and fructo-oligosaccharides (prebiotics) support the skin ecosystem. Ceramide NP contributes to barrier repair. Hydroxydecyl Ubiquinone (modified ubiquinone derivative) provides antioxidant protection. Centella Asiatica Extract and bisabolol modulate the potential irritation from the active ingredients.\u003c\/p\u003e\n\u003cp\u003eApply in the evening after cleansing and toning, patting gently. Retinal is a retinoid — exclusive nighttime use is highly recommended. SPF 50+ in the morning is mandatory, as explicitly stated by the brand on the packaging. This serum is contraindicated during pregnancy and breastfeeding, even at low retinal concentrations — all retinoids are contraindicated regardless of their concentration or regulatory status.\u003c\/p\u003e\n\u003cp\u003eThis serum should not be combined on the same evening with another retinoid (retinol, high-dose bakuchiol), nor with an AHA or BHA exfoliant — risk of cumulative irritation. It can be combined in the morning with a TXA serum (TN or TT) to enhance the action on skin tone uniformity during the day, while reserving this serum for the evening. Do not use on broken, injured, or irritated skin.\u003c\/p\u003e\n\u003cp\u003eIn the routine, it should be applied after toner and before cream, as the evening serum step. For those wishing to maximize action on pigmented marks and density, it can be alternated in the evening with Cos De Baha L1 (0.15% retinol) — choosing only one of the two per evening, never both together.\u003c\/p\u003e","brand":"Purito Seoul","offers":[{"title":"Default Title","offer_id":53898334372177,"sku":"PD-0499","price":27.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1032\/7094\/1009\/files\/purito-txa-6-niacinamide-10-retinal-serum-pd-0499-1-hd.jpg?v=1788396475","url":"https:\/\/paradermia.com\/en\/products\/purito-txa-6-niacinamide-10-retinal-serum-pd-0499","provider":"Paradermia","version":"1.0","type":"link"}
