1. Skin Hyperpigmentation Due to Endocrine Disorders
Skin hyperpigmentation often appears more in women during pregnancy and after childbirth, becoming more prominent. Why does this happen? Because during pregnancy, the estrogen hormone levels in a woman's body increase significantly, and after childbirth, they decrease suddenly, causing disorder in the MSH hormone.
When MHS hormone functions inefficiently, it cannot control the tyrosine oxidation process, leading to increased melanin pigment along with the support of melanosome. These melanins are transported to the upper epidermal layer, forming spots, patches, and dark areas on your skin. Hyperpigmentation occurs deep under the skin, not on the surface, so hyperpigmentation caused by endocrine disorders is often challenging to treat. Women should combine both medication and topical treatment for effectiveness.


2. Skin Hyperpigmentation Due to Stress
Stress is a familiar phenomenon in our lives, representing the body's response to any demand, pressure, or threat to the well-being of individuals, both physically and mentally. It can arise from work, life, or relationships, where you constantly feel worried, uncomfortable, under pressure, and dissatisfied with yourself.
Frequent use of stimulants such as alcohol, beer, etc., affects health and disrupts daily life, leading to insomnia, anxiety, nervousness, and always being in a tense state, which increases free radicals, enhances the oxidation process of Tyrosine into Melanin pigment... are factors causing issues with pigmentation, acne, and wrinkles. Moreover, during the process of treating pigmentation, if stress persists, it will reduce the absorption of medication applied to the skin, prolonging the pigmentation treatment process and making it less effective.


3. Skin Hyperpigmentation Due to Sun Exposure
The body synthesizes vitamin D when exposed to sunlight, but not all sunlight exposure times are beneficial. During midday and afternoon, when the sun shines intensely, ultraviolet rays (UV rays) emitted pose significant harm to your skin.
UVA rays penetrate deep into the skin, attacking the dermis layer, causing various skin conditions such as wrinkles, pigmentation spots, dullness, freckles, skin cancer, and immune system suppression when exposed to sunlight for extended periods. UVB rays, on the other hand, directly impact the surface epidermal layer of the skin, making it susceptible to sunburn, peeling, and discoloration (due to increased production of red-brown pigment). Therefore, when going out, the first thing you should do is apply sunscreen and wear a mask to minimize the harmful effects of UV rays on your skin.


4. Hyperpigmentation Due to Cosmetic Overuse
Nowadays, cosmetics have become indispensable for women. Using foundation and lipstick makes our faces appear brighter, rosier, and more vibrant, boosting our confidence when socializing with friends. However, little do we know that whitening cosmetics often contain strong exfoliants, and lipsticks with high lead content provide better color and longer-lasting effects. Many users of substandard cosmetics suffer from allergies and skin peeling.
Excessive use of skin whitening products with exfoliating properties can cause erosion and thinning of the skin, replacing it with a new, thin, and weak layer. When exposed to sunlight without adequate protection, UV rays penetrate the new epidermal cells (young skin), causing sunburn, darkening, hyperpigmentation, or premature aging... Therefore, do not underestimate the side effects of skincare cosmetics. Although they do not directly cause skin hyperpigmentation, they indirectly exacerbate the condition.


5. Genetic Factors Linked to Skin Hyperpigmentation
Another factor contributing to hyperpigmentation is genetic inheritance. Scientists have proven that over 30% of cases of hyperpigmentation are inherited from close relatives. Genetic hyperpigmentation is a common cause that has led many individuals to feel anxious and concerned. If there is a history of hyperpigmentation in the family, it can affect the offspring, often occurring before the age of 30 or even during pregnancy.
If a mother has hyperpigmentation, there's a 20 to 70% chance her child will also be affected, significantly higher than those with unaffected mothers. Genetic hyperpigmentation is challenging to treat as it involves genes and chromosomes, requiring individuals to consult with a doctor to understand their specific condition and find the best treatment approach.


6. Hyperpigmentation Due to Dietary Habits
A diet lacking in fresh vegetables and fruits can lead to nutrient deficiencies and poor blood circulation, resulting in undernourished skin prone to hyperpigmentation, dullness, and age spots. Moreover, certain everyday foods can effectively treat hyperpigmentation but overconsumption of certain items may exacerbate pigmentation due to their high estrogen content.
Mytour presents some common foods that may contribute to hyperpigmentation:
- Wheat, flaxseeds, and products made from these seeds.
- Some types of beans: soybeans and soy milk, red beans, and black beans.
- Tofu.
- Dried fruits and fruit preserves.
- Oats and alcoholic beverages.
- Ginseng.


7. Environmental Pollution as a Cause of Hyperpigmentation
Dust, pollutants, and exposure to excessive ultraviolet radiation can exacerbate the severity of skin pigmentation. Individuals who work in polluted environments with high levels of toxic substances such as smoke, oil, lead, and coal may experience more severe pigmentation issues. For instance, those in the nail industry who regularly use acetone for nail polish removal or individuals exposed to lead soldering fumes in electronics manufacturing.
Regular exposure to such fumes disrupts the normal functioning of the skin, weakening its defenses and making it more susceptible to bacterial infection, leading to skin damage and increased occurrence of hyperpigmentation. Therefore, individuals working in polluted environments should take appropriate protective measures.


8. Prolonged Sitting in Front of a Computer
Computers, phones, TVs, and electronic devices can all emit radiation that affects women's skin, especially those who work in offices regularly. Working in this environment exposes exposed skin areas to radiation, accelerating skin aging.
The elasticity of the skin in the neck, face, and arms gradually diminishes due to reduced collagen structure. These skin areas are prone to damage and loss of external resistance. Therefore, without measures to prevent radiation exposure from computers and electronic devices, skin discoloration will be more pronounced.


9. Liver Dysfunction Leading to Skin Discoloration
The liver plays a crucial role in the human body's detoxification process. When we eat, the digestive system breaks down food into nutrients for absorption and metabolism. During this process, toxins may be produced, and the liver must transform them into harmless forms and eliminate them from the body.
When liver function is impaired, toxins accumulate more, burdening the kidneys with additional work to expel them, leading to kidney strain. Consequently, health deteriorates, and the body becomes prone to heat-related skin issues like pimples, rashes, hives, eczema, allergies, and skin discoloration.


10. Habitual Hair Removal Methods
The cause of facial skin discoloration due to proper hair removal may seem unrelated, but in reality, it's a highly prevalent issue. When we thoroughly remove the layer of facial hair, it enlarges the pores, making them more susceptible to UV rays and dirt, which can penetrate and lead to pigmentation, discoloration.
Moreover, frequent hot wax hair removal can damage the skin, and when exposed to the air, these wounds are easily oxidized, forming melanin. Depending on each person's body, these pigmented spots may fade within a few weeks or make the pigmentation darker. Therefore, adhere to proper facial hair removal techniques.
