A little extra stuff over what has already been mentioned. I had some ugly, crappy, hard skin on my knees for a while and painted my knees for 5 days in a row and came out with my knees looking 10 years younger. Then I had a nasty wrinkle under my chin that seemed to appear overnight so painted it for 3 weeks. Had to paint about every 3 days. Skinned peeled and looked something like the aftermath of a sunburn but what I was left with was awesome. My wrinkled neck is gone. Now mind you these were no 80 year old wrinkles but 43 year old wrinkles. The only thing I can't stand so far is painting my face. Tried that once and it burned like holy smackers! Plus I had a stinging sensation in my eyes. Now I am doing my chest and hope I have the same great results.
