Complications of laser hair removal-How we could reduce them?

Laser hair removal became a very popular intervention, with a permanently increasing number of procedures being performed worldwide. The procedure is often performed by nonmedical personnel, and even by untrained personnel, that could be associated with different kind of adverse events, from mild to serious. The complications associated could be lower if the operators understand the basic of laser physics and the working principles of devices. We propose a simple acronym, WATCH, in order to increase the safety and efficiency of laser interventions.

Butterfly effect and acne-The role of diet.

The authors aim to present the butterfly effect, a concept based on the theory that small changes might have a powerful effect, as an example of the important connection between diet and acne. Western diet is currently a well-known environmental factor which, mainly via the overstimulation of mTORC1 (mammalian target of rapamycin complex 1), is responsible for the development and aggravation of acne and other age-related diseases of civilization. From the authors' point of view, "the butterfly effect" extrapolated to acne and diet depicts the importance of dietary interventions in acne so as to prevent more serious mTORC1-driven diseases of civilization like obesity, diabetes, and cancer.
