Protect Your Skin from the Sun

One of the most important lifestyle tips for managing pityriasis alba is to protect your skin from the sun. Sun exposure can make the patches more noticeable and can also cause them to become darker. Wear a broad-spectrum sunscreen with an SPF of at least 30 every day, even on cloudy days. Make sure to reapply it every two hours, or more often if you are swimming or sweating.

Moisturize Regularly

Keeping your skin moisturized is also important for managing pityriasis alba. Use a gentle, fragrance-free moisturizer to keep your skin hydrated and reduce the appearance of the patches. Apply the moisturizer twice a day, or more often if your skin feels dry.

Avoid Irritants

Certain products and activities can irritate your skin and make the patches more noticeable. Avoid using harsh soaps, perfumes, and other skin care products. Also, try to limit your exposure to hot water, as this can dry out your skin. If you have to use hot water, use a mild soap and moisturize immediately after.

See a Dermatologist

If your symptoms are not improving with lifestyle changes, it is a good idea to see a dermatologist. A dermatologist can diagnose your condition and recommend treatments that can help reduce the appearance of the patches. They may also be able to recommend lifestyle changes that can help manage your symptoms.
