Yes. Your skin works hard at renewing itself over night so, when you cleanse in the morning, you are removing sebum (the oily substance that your skin produces naturally to stop it drying out). At the end of the day you need to remove sebum, sweat and any make-up that you may have been wearing. It is scientifically proven that a cleansed skin is better able to breathe. Cleansing your skin also ensures that it is able to absorb the active ingredients in your care products.
