Make sure you know what you are doing before you set on this journey with a beauty pen. Basically the heads are made of tiny needles that barely poke the skin, therefore allowing tightening while healing. There are many details to how this works, the size and number of needles in the pen heads, and more. I did this to one side of my area around my cheek and chin, as I wasn’t ready to go near my eye area. I found the settings for me where it’s barely a sting, and I do feel the skin looks better. This is not a thing for a beginner to do without research for sure. The Dr Pen system is known to be among the best in this area of home treatment. I will keep exploring use of this beauty pen and hope to rejuvenate the rest of my skin as I learn.
