It actually can be a great time to do laser treatments in the summer. Since it is so hot, patients are more likely to stay indoors. The UV index is high all year long in Arizona, so when it is cooler out you may end up staying outside longer and get more UV exposure. Regardless of the time of year, sun protection and minimizing exposure is important before and after treatment. When it is the hottest, it may actually be the best time to do treatment since we tend to avoid the outdoors.
