Multiphoton Laser Imaging

The search for a noninvasive test to measure damage to the skin from sun exposure and aging is the Holy Grail of the cosmetics industry.

But proving that a skin cream that promises to turn back the clock really is worth $100 an ounce is only one potential application for the experimental laser technique, Koehler says.

It may also prove useful for evaluating skin diseases like that seen in scleroderma, which is a serious autoimmune disease, as well as a skin complication that can occur in transplant recipients, known as graft vs. host disease.

Koehler and colleagues used the technique, called multiphoton laser imaging, on the inner forearms of seven women and 11 men between the ages of 21 and 84.
