{"product_id":"professional-c-serum-20","title":"Obagi Medical - Professional-C Serum 20%","description":"\u003cp\u003eThe strongest vitamin C in the range, for those already using vitamin C and ready for a higher concentration.\u003c\/p\u003e\n\u003ch3\u003eWhy it works\u003c\/h3\u003e\n\u003cp\u003eVitamin C is primarily an antioxidant. Sun, air pollution, and stress cause the formation of free radicals that damage collagen and cell structures, and vitamin C neutralizes them before they cause damage. The fact that your complexion gradually looks brighter and more even is a result of that protection, not a bleaching effect.\u003c\/p\u003e\n\u003cp\u003eThis serum contains twenty percent L-ascorbic acid, the pure form that the skin can use immediately. It also contains sodium hyaluronate, which binds moisture: a high dose of vitamin C can make the skin feel a bit drier, and the formula partially compensates for this.\u003c\/p\u003e\n\u003cp\u003eThe texture is light and watery and absorbs quickly.\u003c\/p\u003e\n\u003ch3\u003eFor whom\u003c\/h3\u003e\n\u003cp\u003eFor normal to oily or combination skin that already tolerates vitamin C well. A higher concentration here does not automatically mean better results: beyond a certain point, your skin will not absorb more, but it may react more quickly.\u003c\/p\u003e\n\u003cp\u003eIf you are just starting with vitamin C or if your skin is easily irritated, choose the Professional-C Serum 10% or 15% first. Going from 10 to 20 in one step is rarely a good idea.\u003c\/p\u003e\n\u003cp\u003eAlso for those primarily concerned with fine lines rather than spots: vitamin C is needed by your skin to produce collagen, the supportive tissue that keeps it firm. A good step against wrinkles, especially if your skin does not (yet) tolerate retinol.\u003c\/p\u003e\n\u003ch3\u003eHow to use it\u003c\/h3\u003e\n\u003cp\u003eIn the morning, on cleansed and dry skin, before your cream. Five to seven drops for the face and neck, gently press in, and let it absorb for a minute.\u003c\/p\u003e\n\u003cp\u003eAlways follow with high-factor sun protection. Vitamin C and sunscreen complement each other: together they capture more than each does separately, and without the latter, you are missing out on most of the effect.\u003c\/p\u003e\n\u003cp\u003eDo not combine with a retinol or an acid in the same application. One active product at a time.\u003c\/p\u003e\n\u003ch3\u003eWhat I would like to share with you\u003c\/h3\u003e\n\u003cp\u003eBuild it up. Start with three mornings a week, see how your skin reacts, and move to daily use after two weeks if everything remains calm. A short tingling sensation upon application is normal; persistent burning or redness is not: if that happens, take a step back to a lower concentration.\u003c\/p\u003e\n\u003cp\u003eAnd then there is the practical point that really matters with vitamin C: storage. This pure form oxidizes in contact with light, air, and heat. Do not place the bottle on the windowsill or next to the shower, screw the cap on immediately, and count on three to six months after opening. If the liquid turns dark orange or brown, you are applying an ineffective product. I would rather see someone use up a bottle every six months than have one sitting on the shelf for two years.\u003c\/p\u003e\n\u003cp\u003eAre you unsure which concentration suits your skin? Feel free to send me a message, and we can check it together.\u003c\/p\u003e","brand":"Obagi Medical","offers":[{"title":"Default Title","offer_id":56450085257551,"sku":null,"price":158.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/0014\/5999\/files\/343.jpg?v=1789856307","url":"https:\/\/www.beautyplanshop.be\/en\/products\/professional-c-serum-20","provider":"Beauty Plan","version":"1.0","type":"link"}
