{"product_id":"professional-c-serum-15","title":"Obagi Medical - Professional-C Serum 15%","description":"\u003cp\u003eThe medium-concentration vitamin C serum, and for most skin types, the balance between potency and tolerability.\u003c\/p\u003e\u003c!--en--\u003e\u003ch3\u003eWhy it works\u003c\/h3\u003e\u003c!--en--\u003e\u003cp\u003eVitamin C is primarily an antioxidant. Every day, sun, pollution, and stress create free radicals that damage collagen and cell structures. Vitamin C neutralizes these before they can cause harm. The fact that your complexion gradually looks more even and brighter is the result of that protective work, not a bleaching effect.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eThis serum contains fifteen percent L-ascorbic acid, the pure form your skin can use immediately. It also contains ascorbyl glucoside, a more stable variant that is released more slowly, so the effect is more consistent.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eThe texture is light and watery, absorbs quickly, and does not interfere with makeup.\u003c\/p\u003e\u003c!--en--\u003e\u003ch3\u003eFor whom\u003c\/h3\u003e\u003c!--en--\u003e\u003cp\u003eFor normal to oily, normal to dry, or combination skin. This is the concentration I recommend to most people: strong enough to make a difference, gentle enough to use every day.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eIf your skin is easily irritated or you are just starting out, the Professional-C Serum 10% is a gentler start. If you have been tolerating vitamin C without any issues for years, you can move up to 20%.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eAlso, if you are mainly concerned with fine lines rather than dark spots: your skin needs vitamin C to produce collagen, the supporting tissue that keeps it firm. A good first step against wrinkles, especially if your skin does not (yet) tolerate retinol.\u003c\/p\u003e\u003c!--en--\u003e\u003ch3\u003eHow to use it\u003c\/h3\u003e\u003c!--en--\u003e\u003cp\u003eIn the morning, on cleansed and dry skin, before your cream. Five to seven drops for the face and neck, gently press in, let absorb for a minute. Always finish with sun protection: vitamin C and sunscreen reinforce each other, and without the latter, you get much less out of the former.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eUse it in the morning and not in the evening, and not in the same application as a retinol or an acid.\u003c\/p\u003e\u003c!--en--\u003e\u003ch3\u003eWhat I would like to share\u003c\/h3\u003e\u003c!--en--\u003e\u003cp\u003eA vitamin C serum has a shelf life that only starts once you open it. Count on three to six months, and store it in a dark, cool place with the cap tightly closed. If the liquid turns dark orange or brown, its potency is gone. That is not a product defect, that is chemistry.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eAnd don't expect a transformation in a week. During the first few weeks, what happens is primarily something you cannot see: protection. What you will gradually notice, after about eight weeks, is that your skin looks fresher in the morning and pigment spots are less sharply defined. A high concentration can also make the skin feel a bit drier, so a light moisturizer on top is a sensible step.\u003c\/p\u003e\u003c!--en--\u003e\u003cp\u003eAre you unsure which concentration suits your skin? Feel free to send me a message, and we can look into it together.\u003c\/p\u003e","brand":"Obagi Medical","offers":[{"title":"Default Title","offer_id":55149764051279,"sku":null,"price":131.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/0014\/5999\/files\/unnamed_a0087140-17fa-4611-b150-a09c0234a24d.jpg?v=1789857246","url":"https:\/\/www.beautyplanshop.be\/en\/products\/professional-c-serum-15","provider":"Beauty Plan","version":"1.0","type":"link"}
