If there's one skin concern that many people with melanin-rich skin deal with, it's hyperpigmentation.
Those annoying dark spots that just won’t seem to fade—or worse, they get even darker after a pimple or a minor wound. But why does this happen? And why is hyperpigmentation so common in our skin? Today, we’re diving into the science behind hyperpigmentation and uncovering what’s happening beneath the surface.

What exactly is hyperpigmentation?

Hyperpigmentation is a process in which certain areas of the skin become darker due to an overproduction of melanin—the pigment that gives our skin its beautiful color. This can be triggered by various factors such as inflammation, sun damage, or hormonal fluctuations. But did you know that the way our skin responds to these triggers is quite different from lighter skin types?

Why is hyperpigmentation more common in melanin-rich skin?

🔹 Higher melanin production – Our skin is blessed with more melanocytes (pigment-producing cells), which create melanin to protect us from harmful influences like UV radiation and inflammation. However, this also means that as soon as the skin experiences damage—whether from a pimple, a scrape, or irritation—these cells spring into action and produce extra pigment. The result? A dark spot that can linger for months.

🔹 Stronger reaction to inflammation – Melanin-rich skin has a more intense inflammatory response. This means that when the skin is damaged, the body quickly activates a healing process, which often leads to an excessive production of melanin. This is known as post-inflammatory hyperpigmentation (PIH), and it can occur after acne, eczema, or even minor irritation.

I remember once getting a mosquito bite and scratching it nonstop. At the time, it seemed harmless, but soon after, I noticed a dark spot forming where I had scratched. What I had actually done was activate my melanocytes, signaling them to produce extra pigment. And just like that, a stubborn dark spot remained for months! This is how quickly our skin can respond to inflammation and why it’s so important to handle our skin with care.

🔹 Sensitivity to sunlight – While our skin naturally has more protection against sun damage, that doesn’t mean we’re immune to UV rays. In fact, UV exposure can make existing dark spots even darker. Even an old scar that’s starting to fade can reappear or become more intense with too much sun exposure.

🔹 Hormonal influences – Changes in hormones can also worsen hyperpigmentation. Think of pregnancy-related melasma or pigmentation shifts caused by birth control. These hormonal changes can make the skin more prone to discoloration, especially around the mouth, cheeks, and forehead.

Why is it important to understand hyperpigmentation?

Many people immediately turn to harsh treatments to get rid of dark spots, but without understanding the root cause, some methods can actually make things worse. By knowing why hyperpigmentation happens, you can better respond to what your skin truly needs.
