Vitamin C, otherwise known as L-ascorbic acid, is one of the most effective, multifunctional antioxidantswe canincorporate into our skincare routines, known to target everything from the appearance of uneven skin tone to dullness and signs of ageing. When suspended in light silicones – as shown in The Ordinary’s Vitamin C Suspension 30% in Silicone – the ingredient feels even smoother on the skin, ensuring a brightened complexion by morning.
