White spots on skin (leucoderma) can occur for a number of reasons, which we will outline for you in greater detail. But first, it’s important to understand how skin pigment works. Our skin has color because of melanin, which is produced in the skin’s undermost layer. Skin color is determined by melanin concentration. Melanocytes are the cells that are responsible for melanin production.
People with darker skin have more melanin, compared to those with lighter skin. To maintain its color, your skin must regularly produce melanin, so white spots on the skin are a result of melanin loss or underproduction.
Causes Of White Spots And Patches On Skin
In a person with vitiligo, the melanocytes are destroyed so the melanin is not produced. At the onset, white spots will appear and then will grow into white patches. Although there is no cure, there are treatments to slow down or even halt progression of the condition.
Fungus overgrowth on the skin can cause a fungal infection or tinea versicolor. This type of fungal infection causes changes in skin color and begins as small white spots. Normal treatment for tinea versicolor uses topical antifungal or oral medications.
Idiopathic Guttate Hypomelanosis
The cause of this condition is unknown, but white spots begin to appear as a result of aging, so it is common in individuals over the age of 40. Risk factors for the condition include being a female, having fair skin, having family history, and aging.
This condition commonly affects children and adolescents. It begins with white, scaly skin on the face and can become more visible during the summer and dryer in the winter time.
This is a condition involving the loss of color, which occurs when melanocytes get depleted or when tyrosine level decreases. Less melanin is produced, which causes white spots to appear on the skin.
Unlike vitiligo, white spots resulting from this condition are permanent and stable, meaning they won’t progress and become larger. Furthermore, hair on the affected area becomes white as well.
In some cases, white spots on the skin are a result of malnutrition. Having deficiencies in vitamins and minerals can result in white patches, and although harmless they should prompt you to switch to a healthier, more balanced diet.
A pink or brown mole, which is surrounded by white skin – like a halo. Halo nevus is also common in vitiligo patients, and the mole should be monitored regularly to ensure it is not growing.
In this condition, the white patches appear in areas where the skin is thinner – genitals or anus. White spots may be localized or can grow into larger areas.
When morphea is starting out, the skin starts becoming thicker and harder, and discoloration begins with red or purple. As it progresses, the color changes to yellow with white in the middle. Later on, patches can become brown or completely white.
White spots on skin from tanning are due to the harmful UV rays. These white spots are more common in individuals taking birth control or other hormonal medications, as these affect the UV ray absorption.
When the skin becomes damaged – either through burns, medical conditions, or infections – white dots may appear on the skin, and many of them can be permanent. Speak to your doctor about what you can do to treat these white dots.
Although eczema commonly looks like red rashes, it can sometimes present itself in white patches instead. It may be caused by an allergic reaction, so take note of what you are putting on your skin.
