I’m a newbie too micro needling. I’ve always used a derma roller, But derma rollers can be quite abrasive. My first impression after opening the box was that I felt very intimidated. This was such a professional looking piece of equipment, and I am no professional. After reading the instructions I still didn’t feel confident so I watched a few YouTube videos. YouTube gave me a better understanding on this specific tool. After about three tries I feel comfortable and confident. It works best if used with a light moisturizer. And some sort of cooling agent afterwards like an ice globe or cold massager. Just like anything in this world it took some getting used to, around my 3rd or 4th try I felt a lot more comfortable and confident using it. It has a wide range of depth. I now use it without any thought like second nature. My skin feels a lot more smoother and seems to hold moisture better. Overall I am very happy with this pen and I no longer use my derma roller. After some more research I plan on using to combat hair loss.
