12个坏的护肤成分为湿疹

When moisturizers and over-the-counter products just aren’t doing enough, many dermatologists will prescribe glucocorticoid, a topical steroid that has been used to treat eczema for years. (Fun fact: Glucocorticoids are actually found naturally in the body and can help it respond to stress and environmental changes.) But sometimes there are other ingredients within the steroid cream that could cause an adverse reaction. Talk to your dermatologist about patch testing, which could pinpoint other irritating ingredients and help you find a different topical steroid to use instead, suggests Marisa Garshick, M.D., a clinical assistant professor of dermatology at New York-Presbyterian/Weill Cornell Medical Center in New York City.

虽然MCI和MI可以帮助保存产品，但它们并不总是保持皮肤的健康状况。这些成分加入到许多化妆品和个人护理物品 - 包括婴儿用品，护肤面霜和化妆 - 挫败真菌和细菌的生长，并防止产品本身的崩溃。常见的副作用包括在您申请产品或甚至在身体的其他区域的区域上发红，瘙痒或片状。如果你是一个新的父母并在你手上发出刺激，请检查你使用的婴儿湿巾 - 可能是时候尝试新的东西。

Recently named the 2018 Allergen of the Year by the American Contact Dermatitis Society,Garshick博士说，丙二醇在许多护肤品，化妆品，药​​物，食物，以及具有讽刺意味的局部湿疹治疗中。虽然它可以作为一种强大的保湿霜和乳化剂（帮助各种成分混合在一起），但即使您对其过敏而且，它也会导致皮肤脱落。如果您一直使用湿疹的保湿剂或处方霜，请检查它们是否含有丙二醇 - 它很容易成为罪魁祸首。

Francesca J.Brancesca J.倾听Fusco, M.D., an assistant clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City. On the plus side, it has antiseptic properties and is good at killing bacteria. But even a low concentration of the stuff is enough to infuriate eczema. (At a high-enough concentration, it can make even non-sensitive skin red and flaky.)

源自椰子油的东西必须为您的皮肤安全，对吧？不是那么快。椰油酰胺丙基甜菜碱是表面活性剂，一种在清洁产品中的发泡剂 - 洗发水，面部清洁剂，液体肥皂，沐浴凝胶 - 也是尼克斯油和污垢。在表面活性剂尺度上，它在温门者身边，但它仍然可以造成发红和剥落，特别是在眼睛，头皮，手或嘴里，说Garshick博士。

使用带有香味的产品可以是Catch-22 - 它使您的皮肤smellgreat, but not always feel that way. The National Eczema Association (NEA) reports that8% to 15% of eczema patients have a fragrance allergy.并带着香水核算up to 40 percent of allergic reactions from cosmetics，NEA不再考虑其香味的产品验收计划密封。

Finding cleansers and moisturizers without scent isn’t as easy as it should be: Even those labeled “unscented” or “fragrance-free” sometimes still contain a “masking” fragrance, says Dr. Fusco. This is used to cover up unwanted natural odors from herbal or botanical ingredients and can itself cause a skin reaction. “It’s important to check labels for common fragrance ingredients as opposed to just the term ‘fragrance mix,’” says Dr. Garshick. Beware these six, which might contain fragrance: cinnamic alcohol, cinnamic aldehyde, eugenol, isoeugenol (which can be found in nutmeg oil or ylang ylang oil), geraniol (present in many essential oils), hydroxycitronellal, and oakmoss.

香水是湿疹的雷区。最后但尤其是有气味的前线：你可以认为“自然”成分比化学品更少问题，但这不是这种情况。一定的“植物油或其他草药成分可以导致皮肤敏感性，如玫瑰油，香草和甜杏仁油，”Garshick博士说。

The name certainly creates an image of an exotic, good-for-you ingredient. But the sweet-smelling fragrance (and sometimes flavoring agent) can be a big ‘ol N-O for those with sensitive skin and especially eczema. You'll see it in products of all types, including shampoos, deodorants, lotions, air fresheners, pesticides, flavored tobacco, and even certain foods, such as tomatoes, cola, chocolate, and citrus. For extreme irritation where avoiding contact with the topical fragrance isn't enough, you may need to follow a diet low in Balsam of Peru, but discuss this with your dermatologist before trying.

Excellent for wounds, not for eczema. You’ll most often find neomycin sulfate, an antibiotic, in antibacterial ointments and eye drops. It can help fight off bacterial infections when treating wounds or minor cuts. But it can also cause redness, itching, and flaking where it's rubbed on, and Dr. Garshick says that neomycin sensitivity is becoming more common among eczema patients.

Bummer truth: People who are allergic to neomycin may also react to other antibiotics, says Dr. Fusco. So if you have a neomycin allergy, consult your dermatologist about other ingredients you may be allergic to as well.

You may have heard the negative hype about formaldehyde in nail polishes and hair-straightening treatments—it has since been removed from many of those. But it's a popular preservative that, the EPA notes, is also found in many cleaning products, building materials, clothing, fertilizers, and pesticides, and as a经过-product of gas-burning appliances and cigarettes。虽然许多这些产品中的甲醛的实际浓度低，但它仍然可以导致过敏反应，可以加剧湿疹。将眼睛放在成分列表中的甲醛剥离，包括美容产品。

源自绵羊的油腺，经常形成羊毛脂肪，羊毛蜡和羊毛酒精，这种保湿霜具有软化益处，使其在奶油，软膏，润唇膏和化妆品中定期。不幸的是，有湿疹的人比没有对羊毛脂敏感的那些人更有可能。
