A DMK Enzyme Therapy is a professional skin care treatment that uses a special blend of enzymes and minerals to deeply cleanse the skin. The treatment is designed to remove dead skin cells, unclog pores, and brighten the complexion. Some DMK Enzyme masks tighten up as it dries. This tightening action flushes out toxins, removes impurities, increases circulation, and simulate the lymphatic system. The at-home botanical enzyme mask I use by Carolyn's Facial Fitness tightens up quite a bit too. And after it's rinsed off, my face has a bright pink glow and my skin tingles from the increased circulation.
