Vitamin C has proven clinical data supporting its efficacy for short- and long-term improvement for the skin. High concentrations are necessary to achieve optimal results but can sometimes be irritating, depending on one’s skin type. We find that combining Boost with Calm, two products in the The Maas Clinic Skincare line, are the perfect combination and user friendly for all. Apply sunscreen, make-up or no make-up and out the door your go with silk smooth looking skin.
