White patches on the skin can often affect a person's self-confidence. Generally, these patches are not a serious condition and can be treated with the appropriate care. Read on to learn about the potential causes of white patches on the skin and how to treat them.

Causes of White Patches on the Skin

White patches on the skin can arise from a variety of factors such as sun exposure, fungal infections, and autoimmune disorders. Some common causes of white patches on the skin include:

Sunspots

Sunspots is a term often used to describe dark skin patches caused by sunburn. However, it can also refer to white patches caused by sunlight, medically known as idiopathic guttate hypomelanosis.

These white patches develop when there is a reduction in melanin, the pigment responsible for color in the skin, eyes, and hair. The white patches form due to repeated sun exposure, rather than aging factors.

Sunspot treatment can involve the use of steroid or retinoid creams, as well as in-office procedures like dermabrasion, cryotherapy, or chemical peels.

Tinea Versicolor

Tinea versicolor, also known as pityriasis versicolor, is a skin condition caused by an overgrowth of yeast that naturally exists on the skin. This fungal infection leads to rashes that appear as white or light patches. These patches can occur on the face, back, upper arms, chest, neck, and armpits.

Treatment for tinea versicolor includes the application of topical creams, lotions, or antifungal shampoos. In severe cases or when the infection is widespread, doctors may prescribe oral medications.

Pityriasis Alba

Pityriasis alba is a condition that leads to red, scaly, itchy patches on the skin. These patches can heal and leave behind faint white patches. This condition is commonly seen in children between the ages of 3 to 16, often affecting the face, neck, shoulders, and arms.

The exact cause of pityriasis alba is unknown, but experts believe it may be a mild form of atopic dermatitis or eczema. Although the condition often resolves on its own, treatments such as topical calcineurin inhibitors, vitamin D, photochemotherapy, and targeted phototherapy can help speed up the healing process.

Vitiligo

Vitiligo is an autoimmune disorder that causes the skin to lose its natural pigmentation, resulting in white skin patches. This occurs when the immune system mistakenly attacks the pigment-producing cells in the body. Vitiligo patches typically appear on the face, arms, hands, and feet, but can spread to other areas.

Treatment for vitiligo focuses on restoring the skin's original color. Common treatments include corticosteroids, calcineurin inhibitors, and vitamin D analogues.

Milia

Milia are small white bumps that form when the protein keratin gets trapped beneath the skin. This condition is commonly caused by certain skincare products.

Milia typically form on the face, particularly on the cheeks, nose, and chin, though they can also appear on other parts of the body. Both adults and newborns can experience milia.

Milia is harmless and usually doesn’t require special treatment. However, some treatments include the use of adapalene gel or tretinoin cream, prescribed by a doctor. In some cases, a doctor may recommend removing milia through minor surgical procedures or cryotherapy to freeze and eliminate them.

White patches on the skin are generally harmless, but they can impact your self-esteem. If you have concerns about your skin health, it’s best to consult a doctor or use the consultation feature available on the Ai Care app, which can be downloaded from the App Store or Play Store.
