Growing old....
I used my Dermal to lightly burn off my "age spots". It worked wonderfully on the lighter ones. The darker, thicker ones will take a bit longer to treat but the pen is working great. My husband is a retired general surgeon and thinks it works great for my concerns. It isn't as strong as one would find in a clinic environment, but if you are willing to be patient, and only do a bit at a time, it is great!
