Like I said to my other post, this was my first time using this Hydro pen and I hated it. I cannot recommend it. I felt like there was drag, even with using the hyaluronic acid. Moving forward, i’m just going to use my Amazon micro needling stamper at a .25 depth and do one pass in each area and immediately apply the calecim directly after. You could also use your dr skin pen at a low depth as well. I did a deep dive on what is the best product to use with micro needling and hands-down it was this product. It’s patented and made from red deer umbilical cords. It literally tells your skin to, “Wake up, rebuild, restore.” LTKBeauty LTKOver40 LTKGiftGuide
