Melasma is a common skin concern that impacts the aesthetics and psychology of many, especially women. Among the various causes of melasma, hormonal imbalances play a significant and complex role. When the body’s endocrine system is imbalanced, it can lead to hormonal melasma, increasing melanin production and resulting in dark, hard-to-treat patches on the skin. To fully understand why melasma occurs due to hormones, we need to examine the mechanisms through which hormones affect the skin and the risk factors related to lifestyle and overall health.
1. What is Hormonal Melasma and Why Do Hormones Cause It?
Hormonal melasma is a common skin condition where brown or gray patches appear on the skin’s surface, typically on the face. This type of pigmentation disorder is due to an increase in melanin (skin pigment) production. Hormonal changes in the body are one of the primary causes of this condition. Such changes can occur in both men and women, but hormonal melasma is particularly common in women, especially during periods of significant hormonal fluctuations, such as pregnancy, postpartum, or perimenopause. These factors make skin prone to hormonal melasma, affecting confidence and personal aesthetics.
Hormones are essential chemicals in the body that regulate fundamental functions such as metabolism, growth, and skin health. When hormone levels are imbalanced, various health issues can arise, including melasma. Hormonal melasma results from changes or disruptions in the endocrine system, leading to increased melanin production, particularly in areas frequently exposed to sunlight.
One of the most influential hormones related to skin condition is estrogen, the female sex hormone. Estrogen plays a crucial role in maintaining skin moisture, elasticity, and protection against sunlight. However, when estrogen levels fluctuate, for instance, during menstrual cycles, pregnancy, or postpartum, it can make the skin more sensitive, easily damaged, and more prone to developing melasma. Many women experiencing hormonal melasma notice these patches during pregnancy when the body undergoes significant hormonal changes.
Additionally, cortisol—the stress hormone—has a notable impact as well. When the body is under stress, cortisol levels increase, which can disrupt skin structure and lead to pigmentation issues, including melasma. Chronic stress can make melasma harder to treat. Moreover, cortisol heightens skin sensitivity to UV rays, which are a trigger for melanin production.
2. Causes of Hormonal Melasma
Hormonal melasma primarily occurs due to increased melanin production triggered by hormonal fluctuations. Melanin is the pigment responsible for skin color, and its overproduction leads to concentrated pigmentation in certain areas of the skin. This process can happen just below the epidermis or deep in the dermis, making melasma difficult to remove entirely. When skin experiences hormonal melasma, it doesn’t only impact appearance but also serves as a sign that the body’s hormonal balance may be disrupted.
Beyond the effects of sex hormones, other factors within the endocrine system can also lead to melasma. For instance, the thyroid—a gland responsible for regulating metabolism—when compromised, can weaken the body’s ability to fend off environmental aggressors, making skin more susceptible to damage and melasma. Additionally, insulin fluctuations can also affect melasma when blood sugar levels are unstable, leading to increased inflammation, which negatively impacts the skin and heightens the risk of melasma.

Hormonal melasma is often more challenging to treat than other types of melasma. Conventional skin treatments like brightening creams or laser therapies may temporarily improve melasma, but if the underlying hormonal issues remain unaddressed, melasma can easily recur. Therefore, treating hormonal melasma requires a holistic approach, combining hormonal balance with lifestyle and dietary changes, and if needed, hormonal therapies under the guidance of a specialist.
3. Signs of Hormonal Melasma and Treatment Methods
Hormonal melasma often appears when there is a significant hormonal fluctuation, such as during pregnancy, menopause, or prolonged stress. To effectively care for skin affected by hormonal melasma, it is essential to recognize the specific signs and apply suitable treatment methods.
3.1. Recognizing Signs of Hormonal Melasma
Skin affected by hormonal melasma usually exhibits clear, distinct features compared to pigmentation caused by external factors like UV rays or pollution. Key signs of hormonal melasma include:
- Appearance of Brown or Gray Spots: Hormonal melasma typically appears as dark brown, gray, or blue-gray patches or spots on the skin. These patches are often concentrated on the cheeks, forehead, chin, and sometimes on the nose. These areas are prone to hormonal melasma due to an increase in melanin production in response to hormonal imbalances.
- Symmetrical Patterns: One easily recognizable feature of hormonal melasma is its symmetrical appearance on both sides of the face. This differs from sun-induced spots or pigmentation, which often appear scattered and lack a symmetrical structure.
- Difficult to Treat and Prone to Recurrence: Hormonal melasma is generally more challenging to treat and is prone to recurrence if the underlying cause isn’t controlled. Because it is closely related to hormonal status, changes or imbalances in hormones can trigger a recurrence even after successful treatment.
- Emergence During Hormonal Changes: Hormonal melasma often worsens or emerges during phases of hormonal fluctuation, such as pregnancy, postpartum, menopause, or when using hormone-affecting medications like contraceptives. If pigmentation appears or worsens during these times, it is likely hormonal melasma.
3.2. Treatment for Hormonal Melasma
Hormonal melasma is challenging to treat as its root cause lies within the body. Thus, treatment should combine external skin care and internal hormonal balance. Below are some effective ways to improve skin affected by hormonal melasma:
- Hormone Regulation: To effectively treat hormonal melasma, identifying and addressing the root cause is essential. This may involve consulting with a specialist for hormonal therapy, using hormone replacement therapies, or hormone-regulating medications as prescribed. Adjusting hormone levels is crucial to minimize the risk of melasma recurrence after treatment.
- Consistent and Nutrient-Rich Skincare: A consistent skincare routine that includes cleansing, moisturizing, and sun protection is necessary to keep the skin healthy and reduce sun exposure effects. Additionally, products containing antioxidants, vitamin E, vitamin C, and hydrating ingredients will help strengthen the skin’s natural defenses.
- Maintain a Healthy Lifestyle: Internal skin care is essential when dealing with hormonal melasma. A nutrient-rich diet, adequate water intake, and foods rich in vitamins and minerals like fresh vegetables and fruits can support hormonal balance and improve skin health. Sufficient rest, especially high-quality sleep at night, allows the skin to regenerate, prevents aging, and reduces melasma effects.
- Stress Management: Prolonged stress can increase cortisol levels—the stress hormone—in the body, leading to hormonal imbalances that make melasma more likely or severe. Taking time to relax, exercising, and practicing stress-relief methods such as yoga and meditation can help maintain hormonal balance and improve skin health.
- Use of Targeted Skincare Products: Products containing skin-brightening ingredients like kojic acid, niacinamide, vitamin C, or tranexamic acid can help reduce pigmentation and even skin tone. However, as hormonal melasma is hormone-related, these products typically offer only temporary support and should be combined with other treatment approaches.
- Laser or IPL Therapy: Laser and IPL (Intense Pulsed Light) therapies are advanced methods that can effectively treat melasma. Lasers can break down melanin in the skin, fading dark spots. However, without addressing hormonal imbalances, the likelihood of recurrence remains high when relying solely on laser treatment for hormonal melasma.

3.3. Managing Hormonal Melasma Long-Term
For those dealing with hormonal melasma, knowing how to achieve long-term control is crucial. Hormonal melasma requires patience and a combination of external treatments and internal hormonal health maintenance. Balancing daily habits, supplementing necessary nutrients, and following proper skincare routines will strengthen the skin, slow aging, and reduce the risk of melasma recurrence. Implementing these practices not only helps manage melasma but also keeps the skin bright and youthful.
In summary, hormonal melasma is a complex issue but can be significantly improved with the right treatment methods and a healthy lifestyle. This approach not only helps control melasma but also supports long-term skin health and radiance.
