How to Treat Light Spots on Brown or Black Skin
While anyone can develop light spots on their skin, these spots may be more noticeable if you have brown or black skin. There are several reasons why you may see lighter or darker areas on your skin. Here’s an explanation of why you might notice one or more light areas and what you can do about them.
What Causes Light Spots and Patches on Brown or Black Skin?
One common reason for lighter areas on the skin is a reduction in pigmentation. This condition, known as hypopigmentation, refers to a decrease in the amount of pigment produced by the skin. This can happen under the following circumstances:
- Skin injury: Any trauma to the skin can result in lighter spots as the healing process takes time to restore pigmentation.
- Use of certain medications: Some topical treatments or medications can affect pigmentation.
- Cosmetic procedures: Procedures such as laser treatments or wrinkle-filling injections may alter the skin’s ability to produce pigment, leading to lighter patches.
Additionally, light spots may be a sign of an underlying skin condition, including:
- Seborrheic dermatitis
- Tinea versicolor (Pityriasis versicolor)
- Psoriasis
- Eczema
- Lupus
One possible cause of lighter skin patches is vitiligo, a condition where the body starts to destroy melanocytes, the cells responsible for producing pigment in the skin. When these cells are damaged or destroyed, lighter patches of skin appear.
While vitiligo can affect people of all skin tones, it is particularly noticeable in those with darker skin due to the contrast between natural skin color and the light patches.
How to Treat Light Spots and Patches
To provide you with expert advice, we consulted Dr. Nada Elbuluk, MD, MS, FAAD, a board-certified dermatologist and the founder of the Pigmentary Disorders Clinic at the USC Color Skin Center in Los Angeles. Dr. Elbuluk recommends the following three self-care tips for anyone noticing light patches on their skin:
1. Monitor Your Skin Over the Next Few Weeks
Pay close attention to the light areas. Watch for any of the following changes:
- Bright areas becoming darker
- New bright areas forming
- No noticeable changes
Dr. Elbuluk explains, “Light spots may appear in areas where you’ve recently had a rash, insect bite, or injury.” She adds, “When this happens, your body works hard to produce more pigment. How quickly you see pigment return and your skin color recover depends on several factors, including the duration of the rash, bite, or injury.”
“If your skin heals from a rash or other issue within a few weeks, light patches usually improve faster,” Dr. Elbuluk says. You may notice your skin darkening after a few weeks.
“However, when the rash or condition persists for a year or longer, light spots may take more time to heal. Sometimes, you may not see a full recovery,” she explains.
2. When to See a Dermatologist
If you notice new (or worsening) light spots or see no changes after several weeks, it’s time to consult a board-certified dermatologist. A dermatologist can help identify the underlying cause of the light areas on your skin.
In some cases, the light spots may be caused by a skin condition that can benefit from treatment. Dr. Elbuluk notes, “If the light spots are due to a medical condition, active treatment may help. This approach will reduce the risk of additional spots developing.”
3. Protect Light Areas from Sun Exposure
Often, your body will start producing pigment to repair light spots. However, if you expose these areas to the sun, it can cause overproduction of pigment. “Excessive pigmentation can turn light spots into darker spots,” Dr. Elbuluk warns.
To protect your skin from the sun, dermatologists recommend the following tips when outdoors:
- Cover light areas with clothing, such as long sleeves or pants. Stay in the shade whenever possible.
- Use sunscreen on exposed areas of your skin. For adequate protection, choose a sunscreen that offers:
- Broad-spectrum protection
- SPF 30 or higher
- Water resistance
- Reapply sunscreen every two hours, or more often if swimming or sweating.
4. Avoid Self-Treating the Spots
Although there are treatments available, there is no one-size-fits-all solution for light spots. To treat them effectively, you must first identify the cause of the light patches.
In some cases, you may not need treatment at all. Sometimes, the best approach is to allow your natural skin color to recover on its own.
Dr. Elbuluk adds, “A dermatologist can help determine the best course of action for you.” She stresses the importance of seeking professional treatment. If a condition like eczema is causing your skin to lighten, addressing the underlying issue can help prevent new spots from forming.
What to Expect When You Visit a Dermatologist for Light Spots
When visiting a dermatologist, their main goal will be to determine the cause of the light patches. To provide an accurate diagnosis, the dermatologist will closely examine the light areas on your skin and ask you questions about your medical history.
Once the dermatologist understands the cause of your light spots, they will suggest the most effective treatment plan. In most cases, your natural skin tone will gradually return on its own. If a skin condition is responsible, your dermatologist will work with you to create a tailored treatment plan.
To find a board-certified dermatologist near you, search for a dermatology clinic specializing in pigmentation disorders or general skin health.
By understanding the cause of your light spots and working with a dermatologist, you can ensure the best care for your skin’s health and appearance.
