Most people arrive at acne with a theory already in hand. It’s hormones. It’s diet. It’s not cleansing thoroughly enough. It’s blocked pores.

Each of these contains a grain of truth, which is exactly why acne is so often misunderstood. It is not caused by one thing. Modern research shows that acne develops through several interconnected processes within the skin, which is why there is rarely a single product, treatment, or lifestyle change that resolves it on its own.

Acne Is an Inflammatory Skin Condition

For many years, acne was thought to be primarily a problem of blocked pores and bacteria. Today, it is recognised as a chronic inflammatory skin condition. Inflammation plays a role throughout the development of acne and is often present before a breakout becomes visible, which helps explain why treating only the spots you can see is rarely enough.

The Four Main Factors That Drive Acne

Acne is complex, but researchers generally agree that four key processes are involved.

1. Increased Oil Production

The skin naturally produces sebum, an oily substance that helps protect the skin and maintain hydration. In acne-prone skin, the sebaceous glands can become more active, producing larger amounts of oil. This creates an environment in which breakouts are more likely to develop.

2. Abnormal Shedding of Skin Cells

Inside each pore, skin cells are continuously renewed and shed. In acne-prone skin, this process does not always run smoothly. Cells can accumulate within the follicle and mix with sebum, forming the early stages of a blockage. These microscopic blockages, known as microcomedones, are often where acne lesions begin.

3. Cutibacterium Acnes

Cutibacterium acnes is a bacterium that naturally lives on healthy skin. Its presence does not mean the skin is dirty, nor does it mean acne is an infection. However, when conditions within the follicle change, interactions between C. acnes and the immune system can contribute to inflammation and the development of breakouts.

4. Inflammation

Inflammation is not simply a consequence of acne. It is one of the processes that causes it. Inflammatory activity within the follicle contributes to redness, swelling, tenderness, and the formation of visible acne lesions.

What About Hormones?

Hormones play an important role in acne for many people, influencing oil production, inflammatory pathways, and several other processes involved in its development. This is one reason breakouts often shift throughout different stages of life. However, hormones are only one piece of the picture. Many people with acne have entirely normal hormone levels, which is why hormones alone cannot explain it.

Why Genetics Matter

If acne runs in your family, there is a greater chance you will experience it too. Genetics can influence oil production, inflammatory responses, hormonal sensitivity, skin cell turnover, and overall susceptibility to acne. Genetics cannot be changed, but understanding their role helps explain why some skin is more prone to breakouts than others.

There Is No Single Cause of Acne

One of the most persistent misconceptions about acne is that it must have one root cause. In reality, it develops through the interaction of multiple factors. For one person, hormones may play the larger role. For another, genetics and inflammation may matter more. Most often, several processes are occurring at once, which is why effective acne management usually calls for a broader approach rather than a single-target fix.

My Approach to Acne

Because acne is driven by multiple factors, there is rarely a single product or treatment that resolves it on its own. My approach focuses on reducing inflammation, supporting healthy skin function, and building long-term stability within the skin.

For acne-prone skin, I offer a microneedling protocol called Acne Clear Reset. This treatment is designed to support skin regeneration, improve overall skin health, and address some of the underlying processes involved in acne.

For many years, microneedling was considered unsuitable for active acne. More recent research suggests that the same regenerative processes which make microneedling effective for concerns such as ageing and pigmentation may also offer benefits for acne-prone skin when used appropriately.

Every skin is different, which is why each Acne Clear Reset treatment begins with an assessment of your skin, your acne history, and your current home care routine.

A Simpler Approach to Acne Home Care

One of the most common misconceptions in skincare is that acne requires a complicated routine. In reality, consistency tends to matter more than complexity.

For most acne-prone clients, I recommend keeping home care to four essentials:

• A gentle cleanser
• A moisturiser that supports the skin barrier
• Daily broad-spectrum sun protection
• A prescription-strength retinoid, prescribed by your doctor or dermatologist

The retinoid is the treatment step. The cleanser, moisturiser, and sunscreen form the support structure that allows the skin to tolerate it well. My goal is always to simplify the routine and focus on the elements with the strongest evidence behind them.

Looking for Help With Acne?

If you are feeling overwhelmed by conflicting advice, complicated routines, or breakouts that will not settle, you are not alone. My Acne Clear Reset treatment includes professional microneedling together with an assessment of your skin and current routine. From there, I can help you understand what may be contributing to your acne and guide you towards a simple, evidence-based approach to home care.
