The Dr. Pen H5 Hydra Pen is different from a traditional Derma Pen because it combines microneedling with a built-in serum applicator, allowing you to infuse skincare products directly during the treatment. This helps maximize absorption and improve results. Also, the Dr. Pen H5 does not use heat — it works through microneedling only. If you are looking for a device with thermal function, you might consider RF (Radio Frequency) devices instead. Let us know if you need a recommendation!
