Laser Resurfacing
Answer:

I think will give you some visible changes, but they will be mild and not long lasting. When doing fractional resurfacing you are only treating a small percentage of the skin, that is why you can heal so fast. As to RF, many companies claim collagen growth, but that will be mild at best and I would not expect that to last more than 6-12 months in the best of cases. Not a waste of time, but temper your hopes.
