Caucasian skin.

McCurdy said he found radiofrequency resurfacing is the safest and most effective for Asians and other patients with pigmented skin because low-temperature radio wave energy generates less heat.

It uses fewer than 200 degrees Fahrenheit on the tissue vs. more than 1,000 degrees Fahrenheit for some lasers, he said.

It also uses a different type of energy, "disrupting the surface of the skin by ionized particles rather than heat that's generated by laser," he said.

"It's good; I like it," said Kye Kim, one of McCurdy's patients. She said she had a "puka face" because of many pimples at one time.
