A very brief overview of some nonablative clinical uses of lasers is presented. This highlights the most common therapeutic uses for which the safety/adverse events have been evaluated.
Lasers have been used to treat acne [32,56-58], alone or as part of a photodynamic regimen [59-61], and to reverse/correct the scarring produced by more serious cases of this condition [62-66]. It is quite likely that with advances in technology and the identification and selective targeting of key structures, that is, chromophores, a consumer device may become available for treating and/or preventing acne.
A recent application of laser devices is the cosmetic treatment of cellulite. As this is a more recent use of lasers, the clinical efficacy remains to be established. Nonetheless, it has been reported that use of laser treatment together with other agents results in an improvement in the appearance of cellulite [67-70].
