Typically, skin pigmentation refers to the tone of your skin. The quantity and type of melanin made by specialized skin cells known as melanocytes are what dictates it. Usually, improvements in melanin production can cause pigment disorders, such as hyperpigmentation (dark spots), and hypopigmentation (light spots), depigmentation (white spots or scars).
Skin spoilage from acne, blisters, cuts, sun exposure, genetic factors, and autoimmune conditions are all possible causes for improvements in melanin and, thus, skin pigmentation.
Usually, this content discusses skin pigmentation and genetics. It also details skin pigment disorders and how to cure them.
Skin Pigmentation’s reasons
We know that our skin complexion is the result of a complex method during which special cells inside the outer layer of our skin called melanocytes produce melanin.
Under these special skins, cells are organelles (or mini-organs of the cell) called melanosomes. Dissimilarity in the colour of your skin depends on the amount, size, and functioning of these tiny melanin factories.
Here are mentioned two key types of melanin
If we consider eumelanin then this comes in brown and black colours and it saves our skin. It does so by limiting the quantity of harmful ultraviolet (UV) rays that can break through and pick up reactive oxygen radicals which—if left alone—could spoil our cells and DNA and potentially lead to chronic health circumstances like cancer.
If we consider pheomelanin then this comes in yellow and red colours. Opposite eumelanin, pheomelanin offers very little conservancy from UV rays and can support the production of reactive oxygen radicals and the injury they cause.
Generally, our skin pigmentation is determined by the balance of these types of melanin in our skin. All can shift depending on our hormones, interactions with other cells in our body, the impact of certain genes, and so on.
Over 125 genes are known to influence skin pigmentation. Usually, hormones as well as genes are responsible for regulating melanin production methods. They can coordinate how much eumelanin or pheomelanin our skin cells output and how well they survive and function. This reason for shifts in skin colour over time.
Generally, variations in skin pigmentation are trusted to reflect evolutionary adaptations that permitted our ancestors to survive 300,000 to 1 million years ago. As they moved within and outside of Africa, darker skin and lighter skin both came with major pros:
Darker skin helped save people from injurious UV rays in high-sun areas.
A lighter skin complexion allowed others to produce vitamin D more efficiently in places with less sunlight (a key component of the vitamin D synthesis procedure).
Usually, the number of melanocytes you have is pre-determined by heredity. Although, hyperpigmentation and tanning compromise the development and transfer of melanosomes—the organelles that contain melanin.
To conclude, any shift in skin complexion can be concerning or upsetting. If you’re living with skin spoiling or chronic skin circumstances that improve your look, it’s normal to feel stressed out, embarrassed, or frustrated about having to deal with these improvements.
