Brighten the skin & reduce visible signs of ageing with The Ordinary Ascorbyl Glucoside Solution 12%. This Vitamin C packed formula has been designed to effectively brighten the skin tone on the face. The formula contains Ascorbyl Glucoside; this ingredient is a derivative of Vitamin C that is soluble in water. Pure forms of Vitamin C are unstable in water, however, Ascorbyl Glucoside is much more stable & less potent than applying direct Ascorbic Acid. The water compatibility of Ascorbyl Glucoside means that this solution has a pleasant texture, similar to a serum & is comfortable on the skin. Delivering a healthy dose of Vitamin C to skin supports a healthy functioning dermis & has been shown to have significant brightening properties. Products from The Ordinary focus on making clinical technology & functional beauty more widely accessible. every single product is innovatively formulated by a team of chemistry & biochemistry specialists using only ultra-pure & high quality ingredients, producing products that are as gentle & effective as possible. This Solution is free of alcohol, oil, silicone & gluten, it is also cruelty-free & vegan. To use this serum, apply a few drops to the face in mornings & evenings, smoothing over with fingertips before allowing it to absorb.
