PURITO SEOUL, the South Korean brand known for short, gentle formulas, adds NAD+ at 100 ppm and a good measure of niacinamide, and keeps the formula in two layers until you shake it. It is an evening serum for fine lines, firmness and rough texture.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo retinoids work at two speeds.\u003c\/strong\u003e Retinal needs one conversion to become retinoic acid, the form skin acts on, while retinol needs two. Pairing them gives a faster start with a steadier follow-through, and over weeks of use the pair smooths fine lines and refines rough texture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNAD+ adds the newest ingredient in the bottle.\u003c\/strong\u003e Nicotinamide adenine dinucleotide is the coenzyme cells use to make energy, and it has become a talking point in longevity skincare. PURITO lists it at 100 ppm. Topical research on it is still early, so we treat it as a supporting ingredient rather than the headline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNiacinamide and adenosine back up the retinoids.\u003c\/strong\u003e Niacinamide sits seventh on the list, high enough to even tone and support the barrier, and adenosine is a long-established ingredient for the look of fine lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCeramide NP, centella and glycerin keep skin comfortable.\u003c\/strong\u003e Glycerin draws water into the skin, and a little ceramide NP and centella cushion it, which counts most in the first weeks of any retinoid.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTexture \u0026amp; Finish\u003c\/h3\u003e\n\n\u003cp\u003eThe two layers come together with two or three gentle shakes into a light serum that you pat in until it is absorbed.

Retinal is one conversion closer to retinoic acid, so that half of the dose acts faster than the same amount of retinol would. It is a step up from an entry-level retinol, not a first retinoid.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Should I stop if my skin flakes in the first weeks?\u003c\/strong\u003e\u003cbr\u003eA: Not necessarily. Mild dryness and flaking are common while cell turnover speeds up, and they settle as skin adjusts. Drop back to fewer evenings rather than stopping, and stop if redness or stinging carries on.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Where does it go in my routine?\u003c\/strong\u003e\u003cbr\u003eA: Evenings only, after cleansing and toner and before moisturiser. Keep exfoliating acids to different evenings, and wear sunscreen every morning as the last step of your skincare.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use the Retinol Retinal 2000 NAD+ Serum during pregnancy?\u003c\/strong\u003e\u003cbr\u003eA: We recommend pausing it. It contains NAD+, a newer skincare ingredient with no clinical safety data in pregnancy, and two retinoids, which we don't recommend during pregnancy or while breastfeeding. PURITO also advises against using it during pregnancy and breastfeeding.\u003c\/p\u003e\n\n\u003cp\u003eThe number on the bottle is the dose, which is more than most retinoid serums tell you.\u003c\/p\u003e\n\n\u003cp class=\"sn-explore-more\"\u003e\u003cstrong\u003eExplore more\u003c\/strong\u003e\u003cbr\u003eBrowse more \u003ca href=\"\/fr-eu\/collections\/retinol\"\u003eretinol and retinal\u003c\/a\u003e formulas, see our \u003ca href=\"\/fr-eu\/collections\/nad\"\u003eNAD+\u003c\/a\u003e picks, or explore the full \u003ca href=\"\/fr-eu\/collections\/purito-seoul\"\u003ePURITO SEOUL\u003c\/a\u003e range.\u003c\/p\u003e\n","brand":"PURITO SEOUL","offers":[{"title":"Default Title","offer_id":60593164845390,"sku":"PRS23-SN","price":23.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/5057\/0062\/files\/PRS23-SN.png?v=1788115820","url":"https:\/\/skinnomid.com\/fr-eu\/products\/purito-seoul-retinol-retinal-2000-nad-serum","provider":"Skin-Nomad","version":"1.0","type":"link"}
