I recommend consulting a dermatologist to guide and monitor any products you might want to try with your history if you haven’t already. Skinmedica is a favorite of dermatologists and most of my colleagues, both male and female, use this brand! It has hard science to back it up which is spot on. This device does help with toning to a degree but to ward off aging signs like lines and wrinkles you will need some quality products especially with your sensitivity. For your neck and chin I don’t think you will get the results that you are looking for. I wish you luck no matter what you decide. Hopefully one of the other forum doctors will weigh in. Dermatology isn’t my specialty but I do read all the literature for my own aging issues. I’m older so I definitely try and read as much as I can. Again I wish you good luck in finding the right products/devices for you!
