Types of acne and their development
Puberty acne: The hormonal changes during puberty in adolescents can also lead to a dysfunction of the sebaceous glands. They produce excess sebum, which forms calluses and clogs the sebaceous glands. Bacteria can cause painful and sometimes pus-filled pustules.
Acne in adults: Late acne, also known as adult acne or late acne, affects adults from the age of around 25. Puberty acne can often develop into adult acne later in life, but people who have never had acne can also develop it. This can be caused by stress, autoimmune diseases, medication, hormonal imbalances and incorrect skin care.
