{"title":"Ascorbic Acid","description":"\u003cp\u003eAskorbinsyre, også kjent som L-askorbinsyre, er den form for C-vitamin som er mest forsket på når det gjelder hud. C-vitamin er en av de mest potente og virkningsfulle antioksidanter som finnes. Konsentrasjon på 5-20% kan drastisk forbedre aldringstegn som pigmentflekker, rynker og tap av spenst grunnet solskader. Lavere konsentrasjoner som 0,3-2% gir også fordeler, som forbedring av en ujevn hudtone og fine linjer. Askorbinsyre er enda mer kraftfull når den blandes med andre antioksidanter, spesielt vitamin E. Vitamin C er i egen form relativt ustabil, men sammen med vitamin E holde de hverandre stabiliserte og antioksidanteffekten varer lengre.\u003c\/p\u003e","products":[{"product_id":"15-vitamin-c-skin-booster","title":"15% Vitamin C Skin Booster","description":"\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003eThe 15% Vitamin C Skin Booster is specially formulated for mature skin to restore radiance, even out tone, and protect against aging damage.
