Causes and risk factors of common acne
Common acne, also known as acne vulgaris, has various causes and risk factors
Hormonal
Hormonal
Acne is caused by male sex hormones (androgens, especially testosterone), which also increase in women during puberty.
Blocked sebaceous glands
Blocked sebaceous glands
Excessive production of sebum (skin oil) clogs the hair follicles and encourages the formation of comedones (blackheads).
Bacterial infection
Bacterial infection
The bacterial species Propionibacterium acnes multiplies in the clogged follicles and leads to inflammation.
Stress as a risk factor

How is acne diagnosed?
Acne is easy to recognize due to its external appearance, with pustules, blackheads and pimples as clear symptoms. Nevertheless, it is advisable to consult a dermatologist before undergoing independent treatment in order to rule out other skin diseases and to determine the type of acne and the best therapy.
If the doctor suspects an infection, he may be able to take secretions from the blackheads and analyze them to determine which bacteria are causing the infection. The appropriate treatment is determined on this basis.
What measures can be taken for acne?
Prevent
Gentle skin or facial cleansing is important for acne. Special syndets for blemished skin enable gentle cleansing. Avoid greasy products and choose a light moisturizer with an oil-in-water base. When concealing acne with make-up, non-comedogenic products or antiseptic concealer creams should be used. To prevent inflammation and scarring, it is advisable not to squeeze out blackheads and pimples yourself.
Drug treatment
Various therapies are available to eliminate acne. These can be roughly divided into two categories: external (topical) acne treatments, such as ointments and peelings, and holistic (systemic) treatments with internal acne medication.
Home remedy
Home remedies such as healing clay, tea tree oil or sage oil are well-known and frequently used natural options to treat acne or support acne treatment. Healing clay is the best-known home remedy for acne, often used as a supplement to drug therapy. Mixed with water as a paste or powder, it is applied to the skin and dried. The treatment removes fat, sebum and skin flakes and promotes blood circulation.
