Background and Objectives For Asian skin, recent " non-ablative " skin

rejuvenation techniques have become the focus of attention for darker

complected patients. In our earlier research, we have shown that

intense pulsed light (IPL) technology can be applied to Asian skin

with a high degree of safety and efficacy. In this study, we

performed full-face photorejuvenation using a new IPL device

incorporating a 560 nm filter and integrated contact cooling system

for the improvement of various symptoms associated with photoaging in

Asian patients. Study Design/Materials and Methods A total of 73

patients were treated with a series of five or more full-face

treatments at 3-4 week intervals using IPL with integrated contact

cooling. One month after the third and fifth treatments, the patient

and the treating physicians subjectively evaluated improvement in

five areas-in pigmentation, telangiectasia, fine wrinkles, skin

texture, and over-all improvement. In addition, histological changes

were evaluated. RESULTS: Pigmentation improvement, telangiectasia

reduction, fine wrinkle reduction, smoother skin texture, and over-

all improvement were evaluated according to five grades of percentage

improvement. In addition, the subjective rating by the patients and

the physicians was averaged, and the combined results were evaluated.

After the fifth treatment, a combined rating of greater than 60%

improvement was given to more than 80% of patients for pigmentation

improvement, telangiectasia reduction or removal, smoother skin

texture, and overall improvement. Histological evaluations showed

strong staining of Type I and Type III collagen. Complications were

minor and transitory, with burning sensations and erythema in only

two patients. CONCLUSION: Full-face photorejuvenation for Asian

patients using this device is not only effective but is also

associated with fewer post-treatment complications than other more

invasive modalities. We conclude that IPL photorejuvenation can be

the basis for safe and effective skin rejuvenation in Asian patients.
