Thought up by Australian beauty brand Beached, this bronzing serum is packed with ingredients found on the continent, including kakadu plum, a popular fruit extract that is incredibly high in vitamin C, as well as lesser-known illawarra and burdekin plums, which help shield against free radicals to help protect the skin from unnecessary damage. In addition to DHA, the Beached Rays For Days Natural Bronzer Serum (£21) also contains light-reflecting particles that impart an immediate glow, which means you can use it as a serum, mix it in with your moisturiser, or use it as a highlighter on the high points of your face to catch the light.
