MicroChanneling stimulates the body to release peptides, cytokines and growth factors that induce collagen production. As you get older, the stem cells that produce these vital proteins lose efficacy and decline in population, so microchanneling alone becomes less and less effective. Because of premature aging the MicroChannel Delivery Serum, and the post care Cellular Renewal Serum and Healing Accelerator become more necessary to produce improvement. Use of the Livra products ensure the skin continuously receives potent, robust, pristine peptides, cytokines and growth factors even in between treatments. Think of diet and exercise – MicroChanneling without serums is like exercising without dieting. Results will be good with MicroChanneling only, great with serums.
