Medical glossary


Acne is a skin disease characterised by pimples, blackheads or – in severe cases – pustules, mainly located on the face and back. Acne affects both sexes, with increased incidence during puberty, which suggests hormonal imbalances may be the main cause of this disease. However, an unbalanced diet, genetic predisposition, certain drugs, smoking and environmental factors can contribute to the onset or exacerbation of acne.
