I purchased this Mini Freckle Pen to remove some small spots on my arms. What I like about this product is that it is an inexpensive way to remove spots, moles or skin tags. I also like that the Pen has different power modes from mild, middle and high. However, I must admit that the instructions were hard to understand. I tried removal on a few very small spots using the mild power and it did remove the spots. I will be going on to the larger ones as I get more courage. I did not like the burning smell but it works I would suggest using some numbing cream. In addition, I used alcohol on the spots as well as on the needles.
