What causes acne?

Acne usually makes its first appearance during your teenage years, and whilst it doesn’t usually last beyond your late teens, it’s not unheard of to persist throughout adulthood.

Experts explain: watch Medibank health expert Dr Michelle Hunt explain what causes acne.

What causes acne in adults?

Acne occurs when hair follicles in the skin become blocked with oil and dead skin cells, resulting in inflammation and infection. Acne most often appears on your forehead, chin, back and chest – the areas of the skin with the most oil glands. You might be more prone to acne breakouts due to:

• your genetics
• hormonal changes during puberty or pregnancy
• certain medications
• increased stress.

Does junk food cause acne?

Many people believe that eating chocolate or junk food can cause acne, but there isn’t any solid evidence to back this up.

However, it is thought that eating a healthy diet is good for your skin (and we know it’s good for the rest of your body) so aim to eat a balanced diet full of fruit, vegetables, wholegrains and lean protein.
