Hand rejuvenation using standard Intense Pulsed Light (IPL) in Asian patients.

Area of Science:

• Dermatology
• Aesthetic Medicine
• Phototherapy

Background:

• Facial rejuvenation with Intense Pulsed Light (IPL) is popular, but hand rejuvenation remains under-reported.
• Demand for treating dorsal hand lentigines and wrinkles is increasing.

Purpose of the Study:

• To evaluate the efficacy of a standard IPL system using two specific wavelength spectra for hand rejuvenation.
• To assess the improvement of lentigines and wrinkles on the dorsal hand.

Main Methods:

• 128 Japanese patients with dorsal hand lentigines and wrinkles were treated.
• Two wavelength spectra (560-1200 nm and 515-1200 nm) of IPL were applied.
• Treatment efficacy was assessed based on standardized grading for lentigines and wrinkles.

Main Results:

• Excellent or Good results for lentigines were achieved in 60.1% of patients, with dark-toned lentigines showing rapid improvement.
• 25.0% of patients showed effective improvement in wrinkles after the first treatment, with some showing increased improvement after multiple sessions.
• 37.5% of lentigines and 35.9% of wrinkles were unchanged or ineffective after initial treatment.

Conclusions:

• Intense Pulsed Light (IPL) is effective for treating dark-toned and flat senile lentigines on the hands with minimal treatments.
• IPL shows potential for dorsal hand wrinkle improvement, but requires further refinement in application and treatment protocols.
• Overall, IPL presents a viable option for hand rejuvenation, particularly for lentigines.
