Do I need to use any products with the mask?Updated a year ago

You can use a serum to improve the effectiveness of the ingredients, however, this is optional. You can wear the mask with a clean face or a simple moisturiser as well. 

Important: Never use products containing active ingredients (such as Vitamin C or Retinol) on your skin with the LED mask, as active ingredients increase your skin's photosensitivity. The Vitamin C serum included in our bundles is for use as part of your daily routine to help tighten and brighten your skin, but is not for use during your LED mask session.
