I've had lots of places "frozen off" justt had 6 (liveror sun spots) as they are called precancer liquid nitrogen removed from my face. It stings a little then you just feel itrritated, then it kind of rots off.Now my face is clear like when I was in my 20's! Have had so many moles and precancer spots removed, malignant melanoma removed 7 years ago. Not aware of any other alternative therapy other than cutting or shaving these places off. THat kinda leaves nasty scars. Go for the liquid nitrogen and get it over with! Not a big deal and it doesn't' leave a scar!
