The Beautimate Complete Microneedling System brings together the essentials for an ongoing at-home microneedling routine: the Beautimate Microneedle Pen, HYAH Serum and 24 sterile, single-use cartridges. The Microneedle Pen offers two depth settings — 0.25 and 0.5 mm — plus six speed settings for controlled use on the face and scalp. For face routines, the included 2% hyaluronic acid HYAH Serum can be used during and after microneedling to provide lightweight hydration. The Pen includes four cartridges — two 12-pin and two 36-pin — plus the system includes a full 20-pack of 18-pin replacement cartridges. That gives you 24 cartridges total, with different pin counts to use across your routine. New to microneedling or don't need the full 20-pack? The Microneedling Starter Kit is a smaller way to get started.
