Packed with 30% pure vitamin C, Kate Somerville's Mega-C 30% Vitamin C Brightening Facial is a potent yet stable face mask formula that visibly brightens and balances. Thanks to its powerful percentage of L-ascorbic acid (vitamin C), the wash-off mask diminishes the look of dark spots, dullness and discolouration to encourage a more unified appearance. The formula is fortified with sea buckthorn oil, ceramides and bisabolol to nourish and hydrate the skin, plumping it with moisture for a more supple and smooth look while lending soothing and cooling benefits.
