Candee Skin Resources Skin Discoloration Physiology, Causes and Treatments

Skin discoloration is a common and usually harmless condition in which patches of skin become darker than the surrounding area. The darkness may be the result of increased melanin production, exposure to sunlight, or other factors. In most cases, skin discoloration is not a cause for concern and will resolve on its own. However, there are some cases where skin discoloration can be a sign of a more serious underlying condition. This article will explore the physiology, it’s possible causes, and available treatments.

Types of Skin Discoloration

There are many types of skin discoloration, each with its own set of causes and treatments. Here are some of the most common types:

• Pigmentation disorders: These involve changes in the production of melanin, the pigment that gives skin its color. Examples include vitiligo (loss of pigmentation) and albinism (reduced pigmentation).

• Vascular disorders: These involve changes in the blood vessels beneath the skin. Examples include port-wine stains and rosacea (redness and inflammation).

• Inflammatory disorders: These involve conditions that cause inflammation of the skin. Examples include psoriasis and eczema.

• Genetic disorders: These involve conditions that are passed down from parents to children. Examples include ichthyosis (dry, scaly skin) and epidermolysis bullosa (a condition that causes blistering of the skin).

Causes of Skin Discoloration

Our skin is our largest organ and serves as a barrier between our internal organs and the outside world. It helps to regulate our body temperature and protect us from harmful UV rays, bacteria, and other environmental factors. Our skin also provides us with a sense of touch and helps us to absorb vitamin D.

Our skin gets its color from a pigment called melanin. Melanin is produced by cells in the skin called melanocytes. The more melanin that is produced, the darker our skin will be. Discoloration can occur when there is an imbalance in the production of melanin.

There are many different causes of skin discoloration, including:

Hormonal changes: Hormonal changes can cause an increase in the production of melanin, resulting in darker skin. This can happen during pregnancy, puberty, and menopause.

Sun exposure: Exposure to the sun’s UV rays can trigger the production of melanin, causing the skin to tan or darken.

Certain medications: Some medications can increase the production of melanin or cause inflammation, resulting in darker skin.

Skin conditions: Skin conditions such as eczema, psoriasis, and vitiligo

Treatment of Skin Discoloration

There are many treatments available. Some of the most common include:

Topical treatments: These are applied directly to the skin and can help to lighten the appearance of dark spots. Popular topical treatments include hydroquinone, retinoids, tumeric and corticosteroids.

Laser therapy: This treatment uses concentrated beams of light to target and destroy melanin in the skin. It can be effective for treating large areas of discoloration and is often used in combination with topical treatments.

Dermabrasion: This is a procedure that involves using a rotating brush or other abrasive tool to remove the top layer of skin. This can help to improve the appearance of scars and other types of discoloration.

Chemical peels: These treatments use chemicals to remove the top layer of skin, which can help to improve the appearance of dark spots and other types of discoloration.

Skin lightening creams: These contain ingredients that help to break down melanin in the skin, which can help to lighten the appearance of dark spots.

Prevention of Skin Discoloration

There are many ways to prevent skin discoloration. Some people may be more prone to developing discoloration due to their genes or skin type. People with lighter skin are more likely to develop sun spots, for example. There are a few things everyone can do to help prevent skin discoloration, though.

Wearing sunscreen is the best way to prevent any kind of skin discoloration. It is important to choose a sunscreen with an SPF of at least 30 and to reapply it every two hours when spending time in the sun. If you must be in the sun for extended periods of time, wear protective clothing such as long-sleeved shirts and pants.

Exfoliating your skin regularly can also help prevent discoloration. This helps to remove dead skin cells that can build up on the surface of your skin and make it appear dull. You can use a store-bought exfoliating scrub or make your own using ingredients like sugar or coffee grounds. Just be sure not to exfoliate too often, as this can irritate your skin.

Finally, try to avoid smoking and excessive alcohol consumption. These habits can both lead to premature aging of the skin,


There are many different causes of skin discoloration, but luckily there are also many treatments available. If you are concerned about your skin’s appearance, talk to a dermatologist or esthetician to find out which treatment option is right for you. With the right medical care and at-home skincare routine, you can achieve healthy, evenly-toned skin.
