Acne in autumn is one of the most common concerns when temperatures drop, affecting people of all ages. As autumn gives way to winter, many people notice more frequent or intense breakouts. But why does acne seem to worsen in cold weather?
While it is often thought that cold weather only dries out the skin, the science behind winter acne is more complex. Environmental factors, changes in oil production, and the balance of the skin's microbiome contribute to these seasonal breakouts. In this post, we will explore the scientific causes of this autumn and winter flare-up, with an emphasis on the role of bacteria, inflammation, and practical solutions to keep acne under control in the colder months.
The science of acne: the skin microbiome and C. acnes
The skin is much more than a protective layer; it is a living ecosystem with beneficial bacteria that protect and support skin health. This collection of microorganisms, known as the skin microbiota, creates a barrier against pathogens and regulates immune function. However, the balance between "good" and "bad" bacteria is fragile, and when it is disrupted, problems such as acne can arise.
The species Cutibacterium acnes, or C. acnes, is the main bacterium behind acne. It lives naturally on the skin, but when factors such as increased sebum, environmental changes, or hormonal fluctuations disrupt this balance, C. acnes can proliferate. This bacterium feeds on sebum, and as it multiplies, it clogs pores and causes inflammation, leading to breakouts. Environmental factors such as temperature changes, humidity variations, and exposure to irritants can also aggravate acne, making it more difficult to control during these seasons.
Why does acne worsen in autumn and winter?
With the arrival of cold weather, certain factors make the skin more prone to acne. Below are some reasons why acne tends to increase at this time of year:
- Bacterial growth and excess oil – Cold air leads us to spend more time indoors with heating, which dries out the skin. To compensate, the skin produces more sebum, and when this excess oil mixes with bacteria trapped in the pores, an ideal environment is created for C. acnes to multiply, causing breakouts. In addition, as the summer tan fades, breakouts tend to be more visible.
- Increased sebum and inflammation – Dry, cold air irritates the skin barrier, which also contributes to autumn acne. This causes increased oil production, clogging pores and increasing inflammation. For those prone to acne, this increase in sebum production worsens breakouts, leaving the skin redder and more inflamed.
- Less UV light exposure – In summer, mild exposure to UV rays can have a positive effect on acne, regulating the microbiome and the skin's immune response. However, in autumn and winter there is less natural light, which alters this balance. This reduced exposure, along with indoor heating and dry environments, aggravates acne.
- Holiday Stress – The stress generated by social and family gatherings during the holidays can influence sebum production, increasing the likelihood of breakouts. Managing stress is therefore essential to prevent acne in autumn and winter.
Willowherb extract: A natural prebiotic solution against acne
A natural option for controlling acne during the colder months is Epilobium fleischeri extract. This powerful prebiotic promotes the growth of "good" bacteria and keeps acne-causing bacteria in balance, helping to combat autumn acne.
Clinical evidence of the benefits of willowherb
Willowherb extract stands out for its ability to reduce inflammation and bacterial imbalance in the skin. Studies show that it can suppress "bad" bacteria that cause redness and promote beneficial bacteria that strengthen the skin. In addition, Oenothein B, a key component of willowherb, helps control sebum production, promoting clearer and more balanced skin.
- For those who wish to include willowherb extract in their routine, our Ideal Rebalancing Level Serum helps regulate the microbiome and keep the skin balanced throughout the year.
Practical tips for controlling acne in autumn and winter:
- Gentle cleansing – Choose cleansers that clean without over-drying. Preventing skin dehydration is crucial to prevent oil production.
- Keep bedding clean – Wash pillowcases at least once a week to prevent bacteria buildup and transfer to the skin.
- Alcohol-free toners – Opt for alcohol-free toners that hydrate and maintain skin balance. This is especially important in autumn to reduce acne and prevent dryness.
- Balanced detox – Clay or charcoal-based masks or cleansers can help remove dead skin cells without irritating the skin. Good detoxification keeps pores clean and controls acne. We love Charcoal Peace Calming Cleanser.
- Moisturizing products – Cold weather can make acne-prone skin both oily and dehydrated, increasing its sensitivity. To counteract this effect, ingredients that reinforce the skin barrier, such as unsaponifiables derived from sunflower, wheat germ, and olive, are highly beneficial. These compounds help retain moisture while maintaining the integrity of the skin barrier. Our Intelligent Frontier Facial Oil is an excellent option for incorporating these essential nutrients into your autumn/winter routine, promoting a balanced microbiome and reducing irritation. In addition, this facial oil improves the quality of your sebum, which is crucial for autumn acne control.
- Avoid harsh products – Traditional pimple treatments, which often contain high levels of benzoyl peroxide or salicylic acid, can worsen skin dryness and irritation during the colder months. It is advisable to opt for gentler treatments or reduce the frequency of application to prevent skin dehydration.
- Prioritize sleep – Getting enough sleep is essential for regulating hormones and reducing stress, two important factors in controlling acne breakouts.
Skin care in autumn and winter
- Protect your skin outdoors: Covering your face from cold, dry air is essential to prevent autumn acne and protect your skin from irritation.
- Maintain your routine: Consistency in skincare is key, especially if you are following a specific acne treatment. Do not constantly change products to avoid skin imbalances.
When to seek professional help
If autumn or winter acne persists or worsens, it is advisable to consult a dermatologist. A professional can suggest specific treatments that suit your skin type.
Redefining Beauty: Skin Acceptance
Remember that acne is a common condition that affects many people. The skin positivity movement advocates for accepting the skin we inhabit and promotes a healthier, more realistic view of conditions like autumn acne. The goal should not be to achieve perfect skin, but to have healthy, balanced skin free of stigma.
