What Is Hyperpigmentation - Causes and Treatments


What causes Hyperpigmentation (Dark Spots)

First, let's explain the term Melanin.

Melanin is the pigment that gives human skin, hair, and eyes their color.


Now, Hyperpigmentation typically happens when your body produces too much melanin; these dark spots (hyperpigmentation)v can show up as darker patches of skin that show up as small marks, cover wider areas, or even appear all over the entire body.

Many things can cause Hyperpigmentation. Some of the different kinds of Hyperpigmentation


Post-Inflammatory Hyperpigmentation (PIH)

Post-inflammatory hyperpigmentation occurs as a result of acne or other skin inflammations and injuries. It is often associated with acne; a dark spot may be left behind once a pimple heals. PIH can actually happen due to any trauma to the skin. For example, a scratch, or even an insect bite, melanocytes, or pigment cells, can create more pigment in response to the injury. Inflammatory conditions such as lupus and eczema can lead to PIH as well. Although PIH can happen to anyone of any skin color, it is especially common in individuals with darker skin tones.



Melasma

Melasma is the darkening of skin tone due to hormonal changes, usually takes place during pregnancy, and commonly occurs on the face and stomach - Patches of melasma are often gray-brown and occur on the cheeks, forehead, bridge of the nose, chin, and upper lip. This can also be a side-effect of taking birth control.



Rosacea

Patchy areas of redness that occur for no apparent reason can flare up for weeks or months and go away. Common on the cheeks, chin, nose, or forehead, rosacea can be exacerbated by sunlight, temperature extremes, and increased blood flow to the skin. Rosacea can resemble blushing, but more advanced stages are characterized by visible blood vessels and an enlarged nose, chin, and oil glands. Sun can make Rosacea appear worse.



Sunspots
  • Also Known as Age Spots/Photo-aging/Liver-Spots

Sunspots. It emerges as spots on the hands, face, and other areas of the skin that are frequently exposed to the sun over time. These marks have many different names but are all the same and result from years of prolonged sun exposure. Clusters of dark spots may appear in one’s late thirties or early forties. This is because sunlight affects the production of melanin, which results in uneven skin tone.

There is such a thing as Hypo (white) sunspots that we will talk about in another post.
