Correct and brighten your skin with the Bioderma Pigmentbio C-Concentrate, a vitamin C serum suitable for sensitive skin that provides intense pigmentation correction. Bioderma Pigmentbio C-Concentrate contains a potent dose of fresh vitamin C that will reduce melanin production, restore radiance and even out the complexion. The clear gel-cream formula is powered by Bioderma's patented Lumireveal(TM) technology, which treats dark spots by targeting the three biological stages responsible for hyperpigmentation. Not only will the fast-absorbing treatment reduce the look and size of existing dark spots, but it'll also prevent the appearance of new pigmentation spots, in addition to refining the skin's texture, brightening and hydrating for eight hours. Vitamin C isn't the only active ingredient hard at work in this serum. Exfoliating 8% glycolic (AHA) acid and 2% salicylic acid (BHA) provide a gentle peeling effect that boosts cell renewal. At the same time, vitamin E's antioxidant power protects against external aggressors and premature ageing, and vitamin PP intensely moisturises to leave skin smooth and glowing. Why We Love It The worry with many vitamin C serums is that they'll oxidise in their bottles. When this happens, the formula becomes near useless and won't benefit the skin. But the great news is, that won't happen with the C-Concentrate. The experts at Bioderma have created an innovative shake and dose cap to ensure the formula is protected from air and light. It means that vitamin C only gets added to the serum when you're ready to use it - genius! How To Use It Press the dosing cap down to release the vitamin C. Remove the empty cap and screw on the pipette lid. Shake well and mix for ten seconds. Apply five drops to the face and neck every evening for up to 4 months. Tip: Pair your vitamin C serum with a broad-spectrum sunscreen - it's proven to be more effective at neutralising free radical damage than wearing SPF alone!
