About Acne

SFMedica offers an individual acne treatment regime depending on your skin needs and severity of the problem.

Acne is the most common skin condition in the adolescent and young adult age group and is characterised by scaly red skin, blackheads and whiteheads. In its most severe forms it is associated with irreversible scarring.

Acne affects predominantly the face and scalp, the upper part of the chest, and the back where the greatest number of sebaceous glands can be found.

Causes

Acne is thought to be caused by a hypersensitivity of the pilosebaceous unit in response to androgens and in particular to dehydroepiandrosterone sulfate (DHEA-S). As a result sebaceous glands enlarge and overproduce sebum.

There is also an associated excess of keratin (a natural protein found in the skin) within the follicular ducts. The combination of too much sebum and keratin leads eventually to formation of clogs and blockage.

This alteration of the follicular milieu creates an anaerobic environment that favours the proliferation of naturally occurring skin bacteria such as Propionibacterium acnes and Staphylococcus epidermis resulting in inflammation or infection as seen in moderate to severe acne.
