Dr. Jerry Tan, a dermatologist at the University of Western Ontario, told the news source that acne can be very hard on teenagers because it occurs at "a critical point in human development where self-image and confidence [are] being established."
Tan also says that the study does not mean that Accutane and other isotretinoin-based drugs do not cause depression or suicidal thoughts.
"While these results do not exonerate isotretinoin in causing depression, it does suggest that severe acne in and of itself is associated with suicidal [thoughts]," he told the news provider.
In addition to depression, Accutane side effects include inflammatory bowel disease.
