Abstract

Topical photodynamic therapy has shown to be effective for the treatment of several aspects of skin ageing. Multiple studies have demonstrated improvement of fine wrinkles, mottled hyperpigmentation, tactile roughness and sallowness. These results are supported by immunohistochemical analysis that revealed both upregulation of collagen production and increased epidermal proliferation. Neocollagenesis as an indirect dermal effect of photodynamic therapy is stimulated through cytokine induction. This article reviews the available literature for photodynamic rejuvenation while discussing cosmetic effects, light sources, adverse effects and the mechanism of action.
