Photorejuvenation by intense pulsed light with objective measurement of skin color in Japanese patients.

Background And Objectives: This study had two objectives: subjective evaluation of overall skin rejuvenation effects of relatively short-wavelength intense pulsed light (IPL) and objective changes in basic skin tone as measured by a spectrophotometer.

Study Design/materials And Methods: Twenty-five women selected at random received a series of three IPL treatments. Efficacy was evaluated over a 3-month follow-up period.

Is topical anesthesia useful in noninvasive skin tightening using radiofrequency?

Background: The radiofrequency (RF) system has been applied to Asian skin for noninvasive skin tightening. The only drawback is the pain during the treatment.

Objective: The relationships between the effectiveness of a topical anesthetic at various RF levels and the respective treatment results were compared and assessed after 3 months.

Non-ablative skin tightening with radiofrequency in Asian skin.

Background And Objectives: The recent successful application of radiofrequency (RF) in non-ablative skin tightening for skin laxity has attracted attention worldwide. The efficacy and clinical effect of RF were assessed in Asian skin, with additional study on the duration of the effect and any complications.

Study Design/materials And Methods: Eighty-five Japanese females were enrolled in the study for treatment of nasolabial folds, marionette lines, and sagging jowls with 6-month follow-up.

Study of the incidence and nature of "very subtle epidermal melasma" in relation to intense pulsed light treatment.

Background: Skin rejuvenation with intense pulsed light (IPL) is effective for clearing epidermal pigment disorders. Complications are mild and limited to epidermal burns caused by excessive settings. Some patients, however, experience IPL-induced melasma-like hyperpigmentation despite the appearance of normal skin.

Full-face photorejuvenation of photodamaged skin by intense pulsed light with integrated contact cooling: initial experiences in Asian patients.

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.
