How hormonal changes trigger acne breakouts
Why does your skin flare up at the worst possible times? The answer is likely due to your hormones. Hormonal fluctuations are a key factor in triggering acne, especially in women. Life stages such as puberty and menopause, as well as monthly hormonal changes during menstruation, can significantly impact the skin. These changes often lead to increased sebum production, clogged pores, and breakouts.
The role of hormones in skin health
Hormones play a fundamental role in skin health, directly influencing sebum production, inflammation, and overall skin barrier function. The hypothalamic-pituitary-adrenal (HPA) axis is at the core of the body's stress response and has a significant impact on the skin. When activated, particularly during periods of chronic stress, the HPA axis releases cortisol, a stress hormone that not only increases sebaceous gland activity but also compromises the skin barrier, reducing its ability to retain moisture and defend against environmental stressors. Over time, elevated cortisol levels are associated with increased inflammation and oxidative stress, both of which can lead to acne breakouts.
Sex hormones, especially androgens such as testosterone, play a key role in regulating sebaceous gland function. High androgen levels stimulate excessive sebum production, which clogs pores and promotes the growth of Cutibacterium acnes, leading to acne development. Estrogens, on the other hand, promote skin hydration and elasticity, contributing to overall skin health. Fluctuations in estrogen and progesterone during menstruation, pregnancy, and menopause can disrupt this balance, potentially triggering acne.
Hormonal acne and menstrual cycles
The term "hormonal acne" is often used to describe breakouts that occur in response to hormonal fluctuations, particularly in adult women. However, all forms of acne have a hormonal component, as hormones regulate sebum production, which directly impacts acne formation. These fluctuations can lead to breakouts, especially during the menstrual cycle, and are most commonly observed in the lower half of the face, such as the jawline, chin, and cheeks.
During the menstrual cycle, estrogen and progesterone levels fluctuate. In the first half of the cycle, estrogen levels are higher, promoting healthier skin and reduced sebum production. However, in the second half of the cycle, progesterone increases and estrogen decreases. This hormonal shift can lead to increased sebum production and skin sensitivity, resulting in clogged pores and breakouts. Many women experience acne flare-ups just before or during their period due to this hormonal imbalance.
The menstrual cycle is marked by predictable hormonal changes that influence the skin.
Each cycle typically lasts 28 days and can be divided into four phases:
- Menstrual phase (days 1 to 5): Low hormone levels make the skin appear dull and dry.
- Follicular phase (days 6 to 14): Estrogen levels increase, improving skin texture and hydration.
- Ovulation (day 14): A peak in estrogen provides glowing skin, but as progesterone begins to rise, sebum production can increase.
- Luteal phase (days 15 to 28): Progesterone dominates, often resulting in oilier skin and acne breakouts.
The role of toxins in hormonal imbalances and acne
Endocrine-disrupting chemicals (EDCs) are not only harmful to our skin, but they can also affect our general health, leading to reproductive problems, metabolic disorders, and even certain cancers. Studies have shown that these toxins can be passed down four generations through "transgenerational epigenetic inheritance," affecting the health of descendants who were never directly exposed to these toxins.
What are endocrine disruptors? They are a category of toxins that interfere with the body's hormonal system. These chemicals can mimic or block hormones, disrupting the delicate balance of our endocrine system. This hormonal imbalance can lead to overproduction of sebum, clogged pores, and inflammation, all of which contribute to acne.
Bisphenol A (BPA), phthalates, and parabens are common examples of EDCs. BPA, found in plastics, can mimic estrogens and disrupt normal hormonal functions, while phthalates, often found in cosmetics, can interfere with testosterone production.
According to the European Chemicals Agency (ECHA), the process of identifying and regulating EDCs can take a decade or more. Furthermore, once a chemical is identified as an EDC, regulatory processes allow products containing these substances to remain on the market for years before being phased out. For example, products containing recognized EDCs can continue to be sold for seven years.

Manage your stress levels
Since stress directly affects your hormones via the HPA axis, it's essential to incorporate stress-reducing activities into your day. Practices such as yoga and meditation can help regulate cortisol levels and improve skin health.
Regulate your hormones
Regarding monthly hormonal fluctuations, diet appears to play the most significant role.
Diet plays a major role in hormone regulation. Diets high in sugar and processed foods can cause insulin levels to spike, which can trigger excessive sebum production and inflammation. Focus on a balanced diet rich in whole foods, including fruits, vegetables, lean proteins, and healthy fats like avocado, olive oil, and sardines.
For perimenopausal women experiencing acne breakouts, we recommend our Skin & Biotics dietary supplement, a combination of probiotics, prebiotics, minerals, and vitamins. The role of these probiotics is to help regulate hormones while improving gut health.
Regulate your sleep rhythm:
Poor sleep can disrupt hormone production and impair the skin's ability to repair itself. Aim for 7-9 hours of sleep per night to allow your body to balance its hormones and better eliminate the effects of stress.
By combining these strategies, you prepare your body to better manage hormonal fluctuations. You enable your body to more effectively handle hormonal changes, promoting clearer and healthier skin.
