It commonly affects children with dry, sensitive or eczema-prone skin.<\/p>\n<p>The inflammation can be subtle. A patch may initially be slightly dry, rough or pink and then become lighter than the surrounding skin as the inflammation improves.<\/p>\n<p>The cheeks and face are most commonly affected, although patches can also occur on the neck, shoulders and upper arms.<\/p>\n<h2>How Is Pityriasis Alba Related to Eczema?<\/h2>\n<p>Pityriasis alba is closely associated with eczema and atopic skin. In some children, there may be very little redness or itching\u2014the main thing parents notice is the <strong>lighter color left behind by mild inflammation<\/strong>.<\/p>\n<p>Moisturizing the skin, treating active inflammation when needed and protecting the skin from excessive sun exposure can help. The surrounding normal skin may tan while a pityriasis alba patch does not, making the difference in color look much more dramatic during or after the summer.<\/p>\n<p><a href=\"\/medical-dermatology\/atopic-dermatitis-eczema\/\">Learn more about eczema and atopic dermatitis.<\/a><\/p>\n<h2>Pityriasis Alba vs. Vitiligo<\/h2>\n<p>Pityriasis alba is commonly confused with vitiligo, particularly when it appears on the face.<\/p>\n<p><strong>Pityriasis alba<\/strong> usually causes:<\/p>\n<ul>\n<li>Lighter rather than completely white skin<\/li>\n<li>Soft or poorly defined borders<\/li>\n<li>Mild dryness or fine scale<\/li>\n<li>Patches commonly on the cheeks<\/li>\n<li>An association with dry skin or eczema<\/li>\n<\/ul>\n<p><strong>Vitiligo<\/strong> more often causes:<\/p>\n<ul>\n<li>More complete loss of pigment<\/li>\n<li>White patches with clearer borders<\/li>\n<li>Smooth skin without scale<\/li>\n<li>Patches that may occur around the eyes, mouth, hands or other areas<\/li>\n<li>Areas that may enlarge or develop in additional locations<\/li>\n<\/ul>\n<p>Appearance alone does not always tell the whole story. When the diagnosis is uncertain, a dermatologic examination and sometimes a Wood\u2019s lamp examination can help distinguish different causes of light or white skin.<\/p>\n<p><a href=\"\/medical-dermatology\/vitiligo\/\">Learn more about vitiligo.<\/a><\/p>\n<h2>Pityriasis Alba in Brown and Darker Skin<\/h2>\n<p>Pityriasis alba can occur in any skin tone, but it can look much more noticeable in melanin-rich skin because of the contrast between the lighter patch and surrounding skin.<\/p>\n<p>Pigment changes after eczema and other inflammatory skin conditions can also last longer than the original rash. Correctly identifying the underlying condition matters so that a harmless pigment change is not mistaken for vitiligo, a fungal infection or another disorder.<\/p>\n<p><a href=\"\/skin-of-color-dermatology\/\">Explore Skin of Color Dermatology.<\/a><\/p>\n<h2>Does Pityriasis Alba Go Away?<\/h2>\n<p>Usually, yes.

Often the first and most important step is simply determining <strong>why the skin is lighter<\/strong>.<\/p>\n<p><strong>Related Care:<\/strong> <a href=\"\/pediatrics\/\">Pediatric Dermatology<\/a> \u00b7 <a href=\"\/skin-of-color-dermatology\/\">Skin of Color Dermatology<\/a> \u00b7 <a href=\"\/medical-dermatology\/atopic-dermatitis-eczema\/\">Eczema<\/a> \u00b7 <a href=\"\/medical-dermatology\/vitiligo\/\">Vitiligo<\/a><\/p>\n<p><a href=\"https:\/\/l.klara.com\/b8jVLrQpaCXKPX7F\" target=\"_blank\" rel=\"noopener\" style=\"display:flex;align-items:center;justify-content:center;width:240px;max-width:100%;min-height:52px;margin:18px auto;padding:14px 24px;background:#2386BB;color:#FFFFFF;border-radius:8px;text-decoration:none;font-weight:600;line-height:1.2;text-align:center\">Book Appointment<\/a><\/p>\n<p data-service-back-bottom=\"1\" style=\"text-align:left;margin-top:40px;padding-top:20px;border-top:1px solid #d7d7d7\"><a href=\"\/pediatrics\/\">\u2190 Back to Pediatric Dermatology<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evaluation of light or white patches on a child&#8217;s skin, with guidance on the diagnosis, skin care and when follow-up is needed.<\/p>\n","protected":false},"author":163,"featured_media":4378,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_wpcom_ai_launchpad_first_post":false,"footnotes":""},"categories":[39],"tags":[],"class_list":["post-2933","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pediatrics"],"jetpack_shortlink":"https:\/\/wp.me\/phqUFp-Lj","jetpack_featured_media_url":"https:\/\/i0.wp.com\/borealisderm.com\/wp-content\/uploads\/2026\/09\/TEMP-placeholder-Pityriasis-alba-Unsplash-Poko-Skincare.jpg?fit=1080%2C720&ssl=1","_links":{"self":[{"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/posts\/2933","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/users\/163"}],"replies":[{"embeddable":true,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/comments?post=2933"}],"version-history":[{"count":1,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/posts\/2933\/revisions"}],"predecessor-version":[{"id":3221,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/posts\/2933\/revisions\/3221"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/media\/4378"}],"wp:attachment":[{"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/media?parent=2933"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/categories?post=2933"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/borealisderm.com\/zh\/wp-json\/wp\/v2\/tags?post=2933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
