Clearista Refining Pen - Resurfaces Fine Lines and Skin Bumps. Our Skin Pen is also a Great Dark Spot Remover.

Did not do a thing. Sent it back.

According to product description results would take 3-4 weeks. I am not there yet. But here is my experience when I used the refining pen for 90 seconds on a Seborrheic keratoses. My skin got red, raw and peeled a little. I thought the product is actually working to remove the SK but that is not so. One of the ingredients Boric Acid is used in conjunction with another ingredient to neutralize the affect of the acid. This it did as it did not bore a hole in my skin but it did burn and caused my skin to peel off a little. This product contains 5 ingredients while the Clearista pen has only 2 ingredients. Maybe this difference is why it didn't remove the SK.On the plus side after the redness and discomfort disappears the SK itself does feel a little smoother.
