Roll firmly and evenly over skin daily prior to applying serums, working back and forth 4 times in each direction.
Rinse after each use. Clean the roller once a week using a gentle anti-bacterial solution (such as Miltons) found in the baby section of your local supermarket. Dip a toothbrush into the solution and clean only the head of the roller. Do not leave in anti-bacterial solution and always allow to dry after cleaning.
