Photoepilation and skin photorejuvenation: an update

Abstract

The effectiveness of intense pulsed light (IPL) and laser devices is widely accepted in aesthetic dermatology for unwanted hair removal and treatment of a variety of cutaneous conditions. Overall, most comparative trials have demonstrated similar effectiveness for IPL and laser devices. Literature studies alternatively favor the IPL and laser concepts, but the incidence of severe local pain and side effects were generally lower with IPL. IPL phototherapy, already established as a sound option in photoepilation and treatment of photoaging, hyperpigmentation and other skin conditions, is also considered first choice in the phototherapy of skin vascular malformations. When treating large areas, as often required in photoepilation and many aesthetic dermatology indications, IPL technologies show advantages over laser-based devices because of their high skin coverage rate. Compared to lasers, the wide range of selectable treatment settings, though a strong advantage of IPL, may also imply some more risk of local thermal side effects, but almost only in the hands of poorly trained operators. Overall, the strongest advantages of the IPL technologies are robust technology, versatility, lower purchase price, and the negligible risk of serious adverse effects in the hands of skilled and experienced operators.

Photodynamic Therapy Activated by Intense Pulsed Light in the Treatment of Nonmelanoma Skin Cancer

“…The use of IPL as light source for PDT has become more popular for several reasons. Versatility in treating many dermatological conditions, as well as lower commercial costs and more robust technology are strong advantages for IPL devices when compared to lasers [ 19 , 20 ]. In addition, IPL devices have the advantage of the high skin coverage rate.…”

“…Appropriate next steps would include reassurance and discussion of permanent treatment options, which include laser treatment and electrolysis . Laser treatment is the preferred method of permanent hair removal because the risks are negligible and outcomes are better in individuals with dark hair and light skin …”
