Acne

Symptoms

Acne arises when skin pores become blocked leading to a build up of secretions (sebum) within the skin - this creates an ideal environment for an otherwise harmless bacteria called P. acnes to live and multiply. When a large number of these bacteria develop in the trapped sebum, the immune system reacts and causes inflammation - this causes the surrounding area to become red, and the spots become larger and filled with pus.

Acne can be treated with non-prescription topical preparations (creams, gels and solutions) bought over-the-counter or alternatively with prescription topical preparations and tablets, including antibiotics.

Treatments

Treatment should start with low dose topical preparations, before considering stronger topical preparations or antibiotic tablets. You should speak with a GP to decide on what treatment or combination will work best for you. 

Not all treatments are effective in all people. It may be necessary to try different treatments to find the one that is most effective for you.

Severe acne with scarring needs to be treated immediately by consultation with a GP or dermatologist.
