{"product_id":"nourish-barrier-repair-serum","title":"Barrier Repair Serum","description":"\u003cp\u003eA ceramide and niacinamide serum for skin that stings after cleansing. Lightweight enough to layer under sunscreen.\u003c\/p\u003e\u003cp\u003eThe 3:1:1 ratio of ceramides to cholesterol to fatty acids mirrors the proportions found in a healthy skin barrier, which is what the formula is trying to top back up. Niacinamide is held at 5% because more buys little and flushes more.\u003c\/p\u003e\u003cp\u003eIt is light enough to go under sunscreen without pilling. If niacinamide is new to you, use it every other night for the first fortnight; stinging on application usually means the barrier wants the slower pace, not a different product.\u003c\/p\u003e\u003cp\u003eCeramide NP is the specific ceramide most abundant in human skin, which is why it appears here in place of a cheaper generic blend. Phytosphingosine is included as a precursor, so skin can build more of its own over time.\u003c\/p\u003e\u003cp\u003eThe six-month open life is shorter than the cleanser's because the actives degrade, not because the base spoils. At two or three drops twice a day, 30ml runs about that long, which is how the size was chosen.\u003c\/p\u003e","brand":"BuyScout","offers":[{"title":"Default Title","offer_id":48079005941923,"sku":"NOURISHBARR-01","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/8440\/9507\/files\/nourish-barrier-repair-serum-primary.webp?v=1788396203","url":"https:\/\/demo.buyscout.ai\/products\/nourish-barrier-repair-serum","provider":"BuyScout","version":"1.0","type":"link"}
