This thesis summarizes the various factors that contribute to the development of acne, a common dermatological condition that affects millions of people worldwide. Through an in-depth literature review, the role of bacteria, hormones, diet, genetics, hyperkeratinisation and sebum in the onset and severity of acne is detailed. It also focuses on the psychological and social impact of acne, including the negative effects on self-esteem, body image and quality of life. Altogether emphasizing that a complex and adaptive approach addressing both the physical and emotional aspects of acne, including herbal medicines, topical treatments, systemic medications and procedures such as light therapy, lasers and microdermabrasion, are needed not only for the current presence of acne, but also to prevent future recurrences and deal with complications, the most important of which is scarring.
