Acne develops most often on the face, neck, chest, shoulders, or back and can range from mild to severe. It can last for a few months, many years, or come and go your entire life.
Severe acne can produce hundreds of pimples that cover large areas of skin. Cystic lesions are pimples that are large and deep. These lesions are often painful and can leave scars on your skin.
Acne can lead to low self-esteem and sometimes depression. These conditions need treatment along with the acne.
