I'm 60 years old. Considering having these procedures (lipo/Renuvion/mini lift) done to my arms and would like to know from those who have done these 3 things in the arms; pros and cons. I work out regularly. This area just isn't cooperating. I don't want a long scar. This mini would be under my arms. I will use a board certified plastic surgeon who I understand does these quite often. Is the Renuvion enough to tighten my skin? Has anyone done this and had to do Renuvion more than once?
