Types of acne and how to treat them

Did you know that acne is one of the most common skin diseases in Australia?

If you have acne, you’re not alone. It’s the most common skin disease – affecting 85% of Australians aged 15-24 years old*. And it doesn’t matter whether you’re male or female as both sexes get acne.

Acne is usually associated with hormonal fluctuations experienced during your teenage years, however, adults can experience acne too.

Men

Higher levels of androgens (male hormones like testosterone) are present in teenage boys and young men. As a result, they are more likely to have acne and unfortunately, also more likely to have severe acne.

Women

Many women will notice that their acne worsens just before their period.This is due to changes in female sex hormones (such as oestrogen), which can contribute to blockage and inflammation of pores.

Unfortunately, women are more likely to suffer from ongoing acne. In some cases, this means acne can hang around even in your 30s and 40s. Women can also develop acne for the first time later in life and bear the burden of adult acne – a frustrating condition that’s becoming more common and appears to be linked to both hormones and stress.

What causes acne? There are several factors at play including:

Clogged pores, attributed to:

Hormones:

Environmental:

Other triggers:

Types of acne

Non-inflammatory acne: includes whiteheads and blackheads and can usually be treated with over-the-counter treatments and a good skincare routine.

Whiteheads

Whiteheads form when a pore gets clogged by sebum and dead skin cells. The top of the pore closes and a small bump protrudes from the skin. Products containing salicylic acid can be helpful while topical retinoids provide great results for whiteheads.

Blackheads

Blackheads form when a pore is clogged by a combination of sebum and dead skin cells. Unlike whiteheads, the pore stays open. This results in the characteristic black colour seen on the surface.

Inflammatory acne: includes pimples that are red and swollen while sebum and dead skin cells contribute to inflammatory acne, bacteria also play a role in clogging pores. This bacteria can cause an infection deep beneath the skin’s service which can lead to painful acne spots.

Papules (small red, tender bumps)

Papules are small red, tender bumps that occur when the walls surrounding your pores break down from severe inflammation. The result is hard, clogged pores that are tender to touch. The skin around these pores are usually pink.

Pustules (papules with pus)

Pustules can form when the walls around your pores break down and unlike papules, pustules are filled with pus. These pimples are usually red in colour and have a yellow or white head on the top.

Nodules (large, solid, painful lumps beneath the surface)

Nodules are large, solid and painful lumps beneath the surface. Nodules form when clogged swollen pores endure further irritation and grow larger. Unlike papules and pustules, nodules are deep under the skin.

Cysts

Cysts can occur when pores are clogged by a combination of bacteria, sebum and dead skin cells. Congestion occurs deep in the skin and is further below the skin than nodules. Cysts are usually large red or white bumps and are painful to touch. This type of acne is also most likely to scar.
