In case you wonder what that means, it means I left my skin totally uncontaminated with any skincare or cleanser. I merely use mild cleanser and did not bother with all the rituals that I normally do. I am not sure if it is true but I like to leave my skin to be totally clean for a few days and then, start back the regular cleansing ritual.
I notice that my skin gets better after each rest. Otherwise, they don't seem to react to the usage of my regular skincare. Moreover, this is a good time to enjoy the extra minutes that I normally need to take care of my skin.
