How risky is Fraxel restore for the hands? Have seen great pictures of results.

Fraxel Re:Store or Dual can rejuvenate the skin on the hands, resolving hyperpigmentation and creating more volume by stimulating the production of elastin and collagen. In the hands of an expert, there really are no risks except transitory side effects such as red skin for a few days. You will probably need three treatments, and then touch ups every year or two. Another great way to make your hands look younger is to fill in lost volume with the dermal filler Radiesse. Radiesse can last a year or more. Be sure to consult a board-certified dermatologist who is an expert with lasers and fillers to help you.

Fraxel restore is a good laser for hands. I treat my patient's hands most of the time when addressing their overall concerns for skin rejuvenation. of note is the fact that the skin on the hands is generally thinner and has pigment changes in addition to skin laxity and volume loss. Fraxel laser alone cannot address all concerns. 

Yes you can have amazing results with fraxel dual reduce the appearance of sun spots and improve skin texture on the face, hands, etc.  Please see an experienced physician to discuss your options.  Good luck with your treatment
