The Renu Pen micro needling pen creates porations in the skin to allow for serums and product to penetrate deeper. By creating these channels in the skin, the product can reach the damaged cells in the dermal layer. This minimal invasive treatment causes microscopic damage which tricks the skin into thinking it needs to repair itself. This allows for direct blood flow to that area and rebuilds the fiberblasts and remodels the collagen. Minimum order - 12 units.
