The Complex Link: Acne and Bacteria Explained

Bacteria and acne: two words that evoke the sweaty, heart-pounding agonies of adolescence and the ‘failing’ skincare routines of adulthood. But acne, and the bacteria that inhabit our skin, are much less straightforward than we might think. Acne has to do with our existence, not just as individual bodies, but as bodies in communities. Your skin is not just a part of you.

Imagine that your skin is a city – a bustling megacity at that – teeming with economic activity and diverse in its population. Now let’s assume that this teeming megacity has a population of 1 billion people – that’s about the same number of cells your skin has! Of course, this city is inhabited by many different types of people, some of whom are tourists. But one of the permanent residents is Propionibacterium acnes insecta, or P acnes for short. These bacteria are not villains, so you might ask why we should pay attention to them.

But wait, it gets more interesting. P acnes live best in high concentrations of sebum, the oil produced naturally by our skin. Over-production of sebum sets up the perfect environment for the P acnes to thrive. Hence the development of acne.

However, acne is not strictly the product of bacteria alone. Hormones, diet and environmental stressors can interfere with the balance of skin microbiota, igniting inflammation and ending in pustules.

So far, so good. Here’s where it gets interesting. Since P acnes feeds on the oil our sebaceous glands produce, people with acne have far more bacteria on their skin than those without. Because this fuel supply is carcinogenic, it’s vital that our immune cells disrupt the bacterial communities to limit their growth. Normally, T-reg cells keep this at a healthy level. But if, as I consumed enormous quantities of chocolate, my pimples were a symptom of a rampant infection, shouldn’t the solution be simple? Just kill off the bacteria with some antibiotics. Problem solved. Not so. While the drugs successfully reduced P acnes numbers, every antibiotic disturbed the balance of other beneficial bacteria on our skin, serving only to make acne worse in the long term.

What’s the answer? Balance. We should be fighting for a healthy equilibrium, not for the destruction of bacteria. Ultimately, we need to rebuild the landscape of our skin. We want the pathogenic foreign species to leave – but we also have to allow for the presence of some life. We can do this by embracing a systematic approach to skin health – one that addresses the root of the problem.

This can be achieved by employing specific hormonal and behavioural manipulations (through diet and stress management) of oil production. This way, we can help maintain a healthy and balanced microbiome of the skin that will prevent the formation of acne before it erupts.

Yet, as is often the case, navigating this middle path is challenging – requiring the patience, persistence and willingness to continually tinker with a skincare regime and lifestyle shifts in order to see the results we desire. That’s not to mention that it might require professional advice from a dermatologist, who can suggest the best course of action depending on individual needs.

So, at the end of the day, it’s not just skin deep. Acne isn’t a simple entity and it will take more than a one-note treatment to keep our skin healthy and clear. But by taking a holistic view of how bacteria play into outcomes, we can all make better choices to keep our faces beautiful. Let’s embrace the complexity and finally achieve that skin that’s softer than velvet and brighter than the sun.

Questions and Answers:

How do Propionibacterium acnes (P. acnes) bacteria contribute to acne development?

P acnes bacteria help cause pimples when the body overproduces the skin oil, which bacteria feed on. Sebum is oil produced by sweat glands and sebaceous glands. An imbalance can provoke acne.

Can antibiotics effectively eliminate acne-causing bacteria?

Although they drive down bacterial populations, these antibiotics also decimate the skin’s biofilm, altering its natural skin balance and allowing for the growth of harmful bacteria. According to Steinert, the treatment might also accelerate the evolution of antibiotic resistance in certain organisms.

What factors contribute to the overproduction of facial oil and subsequent acne formation?

Hormonal changes, dietary decisions, environmental exposures and mood states can all prompt an overproduction of facial sebum, a congenial base for acneace bacteria.

How do P. acnes bacteria act as a defense mechanism for the skin?

In a balanced state, P acnes organisms would occupy the skin space, preventing the growth of potentially harmful bacteria by depriving them of resources.

Can aggressive approaches like Accutane completely eradicate acne-causing bacteria?

And a year later, studies seem to show that with vulgar treatments such as Accutane (which treats acne but is known for its side effects), patients can manage breakouts, to a point. The bacteria, hiding underground like guerrilla fighters, can be strategic, at times even hibernating or multiplying in random clusters – a strong case for refraining from aggressive treatments. This is why acne can often return.

How can individuals maintain a healthy bacterial balance to prevent acne?

It is essential to optimize sebaceous-glycerolipid synthesis to prevent acne, rather than just targeting epidermal lipids and sebum flow, in order to restore hormonal perturbations, foster the right nutritional decisions, navigate environmental triggers, and counter psychological stressors that underlie the increase in sebaceous production and bacterial overproliferation.
