The challenges of skin pigmentation
Natural skin color, also known as base skin color, is determined by the amount of melanin available in the skin, inherited from parents and not affected by external factors such as sunlight or hormones. When this amount of melanin is overproduced and unevenly distributed on the skin, will lead to uneven skin tone, change the original skin color.
Just as there are many causes of skin hyperpigmentation (also known as melasma, blackhead), Their manifestations are also very diverse, creates many different types of brown spots on the skin.
Overview of common types of hyperpigmentation:
1. Nam da (Melasma)
| Melasma is formed due to hormonal changes, affects the melanin production process in the body. These changes often appear during pregnancy or when using birth control pills, leading to dark areas of skin, most commonly found on the forehead, cheeks and upper lip. Melasma spots often have the form of patches or are symmetrical like a mask. Treating hormonal melasma is challenging because hormones affect the skin continuously 24 hours a day. |  |
2. Sunspots
| Brown spots are the result of long-term overexposure to UV rays and are considered the most common type of hyperpigmentation. They often appear as brown spots on areas of skin that are frequently exposed to sunlight, such as the hands, neck, chest, and face. |  |
3. Post-inflammatory hyperpigmentation (PIH)
|
Post-inflammatory darkening is the result of inflammation or skin damage (e.g. acne, deep cuts or burns). Sensitivity to PIH often increases with age, as cell regeneration slows down, causing dark spots to fade longer. |

Who experiences uneven skin tone?
The short answer is: although more common in adulthood, almost everyone can experience uneven skin tone at some point in their lives. Because we are all exposed to the factors that cause skin pigmentation issues mentioned above, people of all races can be affected by uneven skin tone and dullness.
