Use The Ordinary Vitamin C Suspension 23% + HA Spheres 2% to brighten the skin and reduce multiple signs of ageing such as wrinkles and fines lines. Formulated using L-Ascorbic acid (23% pure vitamin C) and dehydrated spheres of hyaluronic acid, this product will help brighten your skin tone, reduce the appearance of wrinkles and fine lines and minimise imperfections in texture. This product is developed without any water, and this helps the L-Ascorbic acid remain stable. It comes in a suspension of extremely fine L-Ascorbic acid powder which provides direct exposure to the highest concentration of vitamin C topically. When using this product, you can either use it as is or mix it with a moisturiser or serum. When used on its own, this formula feels grainy on the skin for a few seconds after application. A very strong tingling sensation is expected during the first few weeks until your skin increases its tolerance to such high concentrations. Apply to face after cleansing and toning, preferably at night. It is suitable for oily, dry, normal and combination skin types.
