What are the long-term visible impacts of acne?

Red/brown post-acne marks may appear because injured skin may turn red when the tone is fairer and appear brown when tone is richer in color. Also, post-acne scars may surface as indentations on the skin, which are often described as ice pick scars. Therefore, it is important to address acne early because it is treatable and manageable which helps to minimize post-acne marks and scars.
