Tissue had regrown over the affected area after four days, and redness lasted six days.
According to the researchers, healing time averaged five days per treatment, which included time it took for redness and peeling to completely subside.

Turning back the clock by turning to a smorgasbord of cosmetic and surgical procedures continues to be a great American pursuit.
In 2005, nearly 11.5 million surgical and non-surgical cosmetic procedures were performed in the United States, according to the American Society for Aesthetic Plastic Surgery.
A second study in the same issue of Archives of Dermatology found that "dermal fillers" used to smooth out wrinkles work by stimulating the production of collagen.
Perhaps the most popular of these fillers is one containing hyaluronic acid.
Curiously, the effect of the injections lasts six to 12 months, even though the hyaluronic acid only lasts hours to days in the skin. These researchers wanted to find out why.
"We found that these filler injections stimulate production of collagen, which is a major structural protein in the skin which essentially gives youthful skin a nice, smooth appearance," said Dr. Frank Wang, lead author of the study and a clinical research fellow at the University of Michigan, Ann Arbor. "So, we believe that this stimulation of collagen imparts some of the cosmetic effects." This is in addition to the space-filling effects of the substance, Wang added.
The findings may open the door to other applications for the product.
"Perhaps this filler could be used for skin conditions in which collagen is deficient, for instance, in patients who use potent steroids," Wang said. "We haven't tested this, but, based on observation, it's possible that it could have use in this area in addition to the cosmetic use that it's currently approved for."
