The Redox Laboratory was established in 2007 and aims to study aspects of redox regulation and homeostasis related to human skin. The laboratory focuses on the role of reactive oxygen species being (i) beneficial – in relation to its use in combating skin cancers using photodynamic therapy, and (ii) detrimental – the need for antioxidants in preventing UVA - induced skin cancers in human skin.

Pigmentary-associated disorders such as vitiligo and the healing of burn wounds is another chief focus. Other projects include the molecular basis of photorejuvenation using laser-based photodynamic therapy (PDT), the use and abuse of skin lighteners in Africa, and Vitamin D synthesis and its relation to human pigment.
