Eczema is a common skin condition that causes inflammation, redness, dryness, and itchiness. In some cases, eczema can leave behind white spots on the skin after the rash or irritation has healed. These white spots can be concerning, but they are generally harmless. Understanding the cause of these white spots and how to address them can help you manage and potentially prevent their appearance.
What Causes Eczema White Spots?
Eczema white spots are often the result of post-inflammatory hypopigmentation. This term refers to a loss of skin pigmentation that occurs after an inflammatory process, such as an eczema flare-up. When the skin is irritated, inflamed, or scratched, it can temporarily lose its ability to produce melanin, the pigment responsible for skin color. This leads to lighter spots or patches on the skin.
There are several reasons why eczema can lead to white spots:
Skin Healing After Eczema Flare: As eczema heals, the skin may not produce enough melanin in the affected areas. This can leave light spots where the eczema once was.
Scratching and Irritation: Constant scratching and irritation of eczema can damage the skin, which can also lead to pigmentation changes as the skin heals.
Sun Exposure: Sometimes, areas affected by eczema are more sensitive to the sun. When these areas are exposed to sunlight, they can become lighter than the surrounding skin.
Use of Steroid Creams: Prolonged use of steroid creams, which are commonly used to treat eczema, can cause thinning of the skin, which may also contribute to pigmentation changes.
Can Eczema White Spots Be Prevented?
While it may not always be possible to prevent white spots from forming after an eczema flare, there are steps you can take to reduce the risk:
Avoid Scratching: Scratching can worsen eczema and lead to further damage to the skin, which increases the likelihood of white spots. Use moisturizers and other soothing treatments to calm the skin and reduce the urge to scratch.
Use Non-Steroidal Treatments: If you’re concerned about steroid creams causing white spots, ask your doctor about alternative treatments such as calcineurin inhibitors, which can help reduce inflammation without affecting skin pigmentation.
Moisturize Regularly: Keeping the skin hydrated can help prevent eczema flare-ups and promote healing. Use fragrance-free moisturizers that help lock in moisture and keep the skin from becoming dry and irritated.
Protect Your Skin from the Sun: Sun exposure can worsen pigmentation changes. Use a broad-spectrum sunscreen with an SPF of at least 30 to protect sensitive skin areas from the sun’s harmful rays.
Identify and Avoid Triggers: Eczema can be triggered by various environmental factors, such as allergens, harsh weather, and certain foods. Identifying and avoiding these triggers can help reduce flare-ups and minimize the appearance of white spots.
How to Treat Eczema White Spots
While white spots may fade over time, there are several treatment options available that can help improve the appearance of your skin and speed up the healing process.
Topical Steroid Creams and Ointments
Steroid creams are commonly prescribed to treat eczema flare-ups. They reduce inflammation and can help control the itching that often accompanies the condition. While steroid creams can be effective in managing eczema, they may contribute to the development of white spots if used for long periods.
To minimize the risk of white spots, use steroid creams only as directed by your doctor. Be sure to follow their advice on how often to apply the cream and when to stop using it.
Use of Moisturizers and Emollients
Keeping the skin moisturized is crucial in the treatment of eczema. Moisturizers can help soothe and hydrate dry, irritated skin, preventing further damage and promoting healing. Look for products that contain ingredients such as ceramides, hyaluronic acid, and glycerin, which are known to help restore the skin’s moisture barrier.
Apply a thick layer of moisturizer immediately after bathing, when the skin is still damp, to lock in moisture. You can also use emollients like petroleum jelly or aquaphor for extra hydration.
Laser Therapy for Hyperpigmentation
If your eczema white spots are persistent or cause cosmetic concern, laser treatments might be an option. Laser therapy targets the pigmentation issues and can stimulate melanin production, helping to restore the skin’s natural color. Fractional laser therapy is a common treatment for post-inflammatory hypopigmentation, but it’s important to consult with a dermatologist to determine if this is the right treatment for you.
Light Therapy (Phototherapy)
Phototherapy involves exposing the skin to ultraviolet (UV) light under controlled conditions. This treatment is often used for people with eczema to help reduce inflammation and promote healing. For white spots caused by eczema, phototherapy may help the skin regain its normal pigmentation.
However, it’s important to use light therapy only under the supervision of a healthcare professional, as overexposure to UV light can damage the skin and cause further issues.
Topical Calcineurin Inhibitors
As an alternative to steroid creams, topical calcineurin inhibitors such as tacrolimus (Protopic) or pimecrolimus (Elidel) can help manage eczema flare-ups. These medications reduce inflammation and can be effective in treating eczema without causing thinning of the skin or pigmentation changes. Discuss these options with your dermatologist if you’re concerned about steroid use.
Hydrocortisone Cream for Mild Cases
For less severe cases of eczema, hydrocortisone creams may be helpful. These creams contain a mild corticosteroid that can reduce inflammation and relieve itching. While hydrocortisone is less likely to cause pigmentation changes than stronger steroid creams, it is still important to use them as directed and to avoid overuse.
Vitamin D and Skin Health
Vitamin D is essential for healthy skin, and some people with eczema may benefit from increasing their vitamin D intake. Some studies suggest that vitamin D can help improve skin barrier function and reduce inflammation in eczema-prone skin. You can obtain vitamin D through sunlight exposure, diet (fatty fish, fortified dairy products), or supplements. However, always consult with a healthcare provider before starting any new supplements.
When to See a Doctor
If you notice persistent or worsening white spots after an eczema flare-up, it’s important to consult with a dermatologist. They can determine the cause of the white spots and recommend appropriate treatments. In some cases, white spots may be a sign of a more serious underlying condition that requires medical attention.
A dermatologist may perform tests to rule out other skin conditions, such as vitiligo, fungal infections, or post-inflammatory hypopigmentation, which are sometimes confused with eczema-related white spots.
Patience is Key
Eczema white spots can take time to fade. While treatments can help speed up the process, it’s important to be patient and allow your skin time to heal. In most cases, the white spots will gradually fade as the skin regenerates, and the pigmentation will return to normal. However, in some instances, it may take several months for the skin to regain its color.
If you’re concerned about the appearance of your skin or the persistence of white spots, it’s best to speak with a dermatologist who can provide personalized advice and treatment options.
Conclusion
Eczema white spots can be a frustrating side effect of eczema flare-ups, but with proper treatment and care, you can manage and improve the appearance of your skin. By using the right products, protecting your skin from the sun, and avoiding scratching, you can help minimize the risk of these spots forming. If white spots persist, consult with a dermatologist to explore treatment options such as moisturizers, topical medications, or more advanced therapies like laser treatment or phototherapy.
With patience and consistent care, your skin can heal, and the white spots will gradually fade away.
