The Derma stamp 1.5mm won't penetrate the skin no matter how hard I press, either on my neck or my arm. The needles seem not sharp enough to pierce the skin, maybe for safety reasons.
So smooth and works really well! Quality Pen.
Love this pen. It is so easy to use and works wonderfully. NO pain or sticking. Smooth glide with serums.
This has been the most effective product I've used for fat dissolving, you can literally see the dissolving after administering the injection.
When you puncture the skin, it doesn’t release the serum. Somethings wrong with the mechanism. That’s supposed to wet your skin with the serum so that it can soak into the skin, but it does not work.
