Does the CO2 fractional laser work well on removing knee and elbow wrinkles and creepy skin? (photo)

Co2 laser does okay, in some cases.  Typically I have patients doing radiofrequency such as sublative or Velashape.  Over time you can get improvements.  Diluted sculptra to the area works very well too.  In general though, most treatments only give a small improvement for this area.  Best, Dr. Emer.

Morpheus 8 is a non-invasive skin and soft tissue tightening treatment that is consistently amazing in our patients. We use the Morpheus to exact fractional induced RF into the skin or tissue in order to tighten collagen and stimulate contraction of the tissue. For acne scars, it is quite useful to build collagen in patients who have atrophic scars but is not very productive for ice-pick scars which require TCA Cross. For tissue tightening, Morpheus is ideal for the face and neck and we often combine it with CO2 laser or Ultherapy to further enhance results. Chemical peels and skin resurfacing should be done at least 5 to 7 days after, but can be performed earlier, depending on treatment severity. Avoid exfoliating skin treatments before Morpheus and expect a period of 2-4 weeks for skin contraction to set in.

This is a difficult problem to treat and most modalities give only a modest improvement.  Technology is always changing so there could be something in the near future.  Best of luck.
