A serum is a skincare product used under your moisturiser, that contains a high concentration of powerful ingredients that can penetrate deeply into the skin. You only need a little serum, for it to have a big impact. Whether you are looking for vitamin C to brighten and hydrate, salicylic acid to clear or hyaluronic acid to plump, there is a serum just for you.
