Acne Treatment

Klox Technologies and LEO Pharma, a global leader in dermatology, created FB Dermatology, a specialized dermatology company to commercialize Kleresca for the treatment of moderate to severe acne.

Acne vulgaris affects 85% of individuals at some point in their lives. The fact that acne is so common makes it no less heart-breaking to the people who suffer from its physical manifestations such as clogging of the pores, long-term lesions and associated scarring the face, chest or back. Klox understands that acne is a serious medical condition and requires innovative treatments that work and provide long-lasting results, which is what motivated the development of Kleresca.

The treatment is simple and involves applying a thin layer of Kleresca gel to the skin that is to be treated. Then, it is illuminated for nine minutes to generate fluorescent energy designed to address several factors responsible for causing acne while minimizing scarring. Results show durable improvements in the skin that persist for several months after treatment completion.
