Hormones play a central role in our bodies – they influence not only our metabolism, energy levels, and mood, but also the appearance of our skin. Whether during puberty, stressful periods, or throughout life, hormonal fluctuations have a direct impact on moisture, elasticity, sebum production, and even skin aging.
But what happens when the hormonal balance is disrupted? And how do these changes affect the skin's appearance over time?
What exactly are hormones?
Hormones are the body's own messenger substances, involved in almost all bodily functions. They are produced in various glands such as the thyroid, pancreas, adrenal cortex, ovaries, and testes. In total, there are over 30 different hormones that regulate essential processes such as metabolism, immune function, the sleep-wake cycle, and, of course, skin health.
Which hormones affect the skin?
Our skin is very sensitive to hormonal changes – whether due to natural processes like aging or external influences such as stress and diet. Here are the most important hormones that affect our complexion:
1. Estrogen
Estrogen is one of the most important female sex hormones and is produced primarily in the ovaries, but also in the adrenal cortex and adipose tissue. It plays an essential role in numerous bodily processes – from reproduction and bone metabolism to skin health.
Estrogen is particularly beneficial for the skin: it stimulates the production of collagen and elastin – two key proteins that ensure elasticity and firmness. It also promotes the formation of hyaluronic acid, which helps the skin retain moisture better. A high estrogen level therefore results in smooth, plump, and radiant skin – it's no wonder it's often referred to as the "beauty hormone."
However, hormone levels change with age. Even in perimenopause , the years leading up to menopause, estrogen levels gradually begin to decline – with visible consequences for the skin. It becomes thinner, loses elasticity, and no longer retains moisture as well, making it appear drier and fine lines more pronounced. At the same time, collagen production decreases, weakening the skin's structure and promoting the formation of wrinkles .
However, it's not only the natural aging process that affects the balance of this hormone. Hormonal changes, such as pregnancy or starting or stopping birth control pills, can also noticeably alter the complexion. While high estrogen levels often result in a fresh, radiant glow, a sudden drop after childbirth or when discontinuing hormonal contraceptives can lead to dryness or blemishes.
2. Testosteron
Testosterone is primarily known as a male sex hormone, but women also produce this hormone, albeit in smaller amounts. It is mainly produced in the testicles, but also in the ovaries and adrenal cortex. Testosterone plays a significant role in physical development, muscle growth, and sexual health – and it is also crucial for skin health.
Testosterone is primarily responsible for sebum production in the skin. Higher testosterone levels stimulate the sebaceous glands, leading to the production of more sebum, which protects the skin from drying out. This increased sebum production makes the skin appear plumper and smoother, but it can also be a breeding ground for skin problems such as blemishes if the sebaceous glands become overactive.
During puberty , adolescents in particular experience a significant increase in testosterone levels, which can lead to a typical increase in sebum production and potentially to acne. In women, an increase in testosterone levels, for example due to hormonal fluctuations during menopause or certain health conditions, can also lead to increased sebum production and skin blemishes.
As we age, testosterone levels decline in both men and women. This affects the skin, as the decrease in the hormone makes the skin less resilient and reduces sebum production. This can lead to drier skin, loss of elasticity, and more pronounced fine lines or wrinkles. In addition to these natural changes, external factors such as stress or an unbalanced diet can also influence testosterone levels and thus negatively affect the skin. Chronically elevated testosterone levels due to stress or health problems can lead to oily skin and increased blemishes.
3. Cortisol
Cortisol, also known as the "stress hormone," is primarily produced in the adrenal glands and plays a central role in the body's stress response. It helps regulate blood pressure, control metabolism, and prepare the body for a rapid reaction in stressful situations. However, what many don't know is that a persistently elevated cortisol level can significantly impair not only general well-being but also the appearance of the skin.
When cortisol levels are chronically elevated, as can occur with prolonged stress, this accelerates the breakdown of collagen in the skin. A loss of collagen leads to a weaker skin structure, which promotes the formation of wrinkles and sagging skin.
Furthermore, cortisol promotes inflammatory processes in the body. This can exacerbate skin problems such as acne, eczema, and rosacea, as the inflammation irritates and makes the skin more sensitive. Cortisol also affects blood circulation in the skin, which can lead to a duller, more tired complexion . The skin loses freshness and vitality, which, in the long term, negatively impacts its appearance and overall health.
Since chronic stress is a significant trigger for elevated cortisol levels, it is important to pay attention to relaxation and stress management. In the long term, a balanced cortisol level can not only promote general well-being but also stabilize skin health and improve the skin's appearance.
4. Insulin
Insulin is a hormone primarily released after consuming carbohydrates and plays a central role in metabolism. It ensures that sugar (glucose) is transported into the cells to be used as an energy source. But insulin doesn't just affect our blood sugar levels – it also influences our skin in various ways.
A persistently high insulin level, often triggered by a sugary diet or frequent blood sugar spikes after meals, can stimulate sebum production in the skin. This increased sebum production leads to oilier skin and clogged pores. The result is often blemishes, blackheads , and acne , especially on the face, forehead, or back.
Furthermore, high insulin activity affects skin structure. It can impair skin regeneration and cell growth, resulting in an uneven and dull complexion. The skin loses its radiance and elasticity may decrease .
A balanced diet with less sugar and more natural foods can help regulate insulin levels and promote skin health.
5. Melatonin
Melatonin is a hormone primarily released at night that plays a crucial role in regulating our sleep-wake cycle . It helps prepare the body for sleep by making us tired and stabilizing the day-night cycle. Melatonin also has a direct impact on our skin health.
During sleep, when our body enters deep sleep, the skin begins to regenerate. Cell damage caused during the day by UV radiation, pollution, and other stressors is repaired, and new skin cells are formed. Melatonin supports these repair processes and promotes skin regeneration .
A melatonin deficiency, often caused by lack of sleep or excessive screen use in the evening (blue light), can disrupt these natural regeneration processes. The result is a dull complexion, often accompanied by reduced skin elasticity and an overall tired appearance. In the long term, chronic sleep deprivation can also accelerate the skin's aging process by promoting collagen breakdown and weakening the skin's structure.
Therefore, make sure you get enough sleep and reduce your screen use in the evening to support the natural melatonin level and thus promote skin regeneration overnight.
6. DHEA
DHEA (dehydroepiandrosterone) is a hormone primarily produced in the adrenal glands and plays a key role in hormonal balance. It reaches its peak in young adulthood, when the body is at the height of its physical health. DHEA influences a variety of bodily functions, including those of the skin. It contributes to maintaining skin hydration, elasticity , and resistance to external environmental factors.
However, DHEA levels gradually decline with age. This decline also affects the skin. A drop in DHEA levels leads to a decrease in skin hydration and firmness. This makes the skin more prone to dryness and less elastic. At the same time, cell regeneration slows down, making the skin less resistant to external stressors and damage.
The natural decline in DHEA is one of the main reasons why skin becomes thinner and more sensitive over the course of a lifetime. In later years, skin is often less able to regenerate quickly and shows the first signs of aging, such as fine lines and a loss of firmness.
What can be done to support hormonal balance?
If you feel that hormonal fluctuations are strongly affecting your skin, it may be helpful to approach the issue holistically:
- Consult a doctor or dermatologist: In case of persistent skin problems or strong hormonal fluctuations, a hormone check can provide information.
- Adjust your diet : A balanced diet with healthy fats, plenty of vegetables and little sugar can help stabilize hormone levels.
- Get enough sleep and reduce stress : Relaxation techniques such as meditation or exercise can help lower cortisol levels.
- Targeted skincare : Products with soothing, moisturizing, or regenerating ingredients can support the skin while the hormonal balance is regulated.
Hormonal balance for healthy, radiant skin
Our hormones are largely responsible for how our skin looks and feels. They regulate moisture, elasticity, sebum production, and the aging process. Hormonal fluctuations are a natural part of life, but understanding the effects of these changes allows us to respond effectively. By adapting our skincare, diet, and lifestyle to our hormonal needs, we can improve our complexion in the long term and maintain healthy, radiant skin.
