Time for some myth-busting! There is no versus when it comes to using a Vitamin C Oil or Vitamin C Serum, because they’re designed to work very differently from each other. Serums contain active ingredients that penetrate the deeper layers of the skin, whilst facial oils work to protect the outer layer - which is why it makes good skin sense to use both. 🌟Use Vitamin C Super Glow Facial Oil in the morning to give your skin maximum protection and radiance throughout the day. 🌟Apply Advanced Brightening Vitamin C Serum at night so you wake with a radiant glow the next day. 🌟If your skin loves Vitamin C and is extra thirsty you can double up - by applying your Serum, before applying your Oil and then your moisturiser.
