Seborrhoeic Dermatitis | Everything You Need To Know

#seborrheicdermatitis #skincare

Seborrheic dermatitis is a common skin disease that causes an itchy rash with flaky scales. It causes redness on light skin and light patches on darker skin. It's also called dandruff, cradle cap, seborrhea, seborrheic eczema, and seborrheic psoriasis.
Causes:
It might look similar to psoriasis, eczema, or an allergic reaction. It usually happens on your scalp, but you can get it anywhere on your body.
Experts don't know what exactly causes seborrheic dermatitis. It seems to be a mix of things, including:
Stress
Your genes
A yeast that usually lives on your skin without causing problems
Certain medical conditions and medicines
Cold, dry weather
An immune system response
Symptoms:
Babies 3 months and younger often get cradle cap: crusty yellow or brown scales on their scalp. It usually goes away before they're a year old, although it can come back when they reach puberty.

Parents might mistake seborrheic dermatitis for diaper rash.

Adults might get seborrheic dermatitis on their face, especially around their nose, in their eyebrows, on their eyelids, or behind their ears. It can show up on other parts of your body, too:
In the middle part of your chest
Around your navel
On your buttocks
In skin folds under your arms and on your legs
In your groin
Below your breasts
Your skin might itch or burn. The scales that flake off could be white or yellowish and look moist or oily.

Because seborrheic dermatitis can look like other skin conditions, see your doctor to get a diagnosis and a treatment plan.

#脂溢性皮炎 #护肤

脂溢性皮炎是一种常见的皮肤病，会引起发痒的皮疹和片状鳞屑。 它会导致浅色皮肤发红，深色皮肤出现浅色斑块。 它也被称为头皮屑、乳痂、皮脂溢、脂溢性湿疹和脂溢性牛皮癣。
成因：
它可能看起来类似于牛皮癣、湿疹或过敏反应。 它通常发生在你的头皮上，但你可以在身体的任何地方得到它。
专家们不知道脂溢性皮炎到底是什么原因引起的。 它似乎是各种事物的混合体，包括：
压力
你的基因
一种通常生活在皮肤上而不会引起问题的酵母
某些医疗条件和药物
寒冷、干燥的天气
免疫系统反应
症状：
3 个月及以下的婴儿通常会出现乳痂：头皮上出现硬皮状的黄色或棕色鳞屑。 它通常会在他们一岁之前消失，尽管当他们进入青春期时它会回来。

父母可能会将脂溢性皮炎误认为是尿布疹。

成年人的脸上可能会患上脂溢性皮炎，尤其是鼻子周围、眉毛、眼睑或耳后。 它也可以出现在你身体的其他部位：
在你胸部的中间部分
肚脐周围
在你的臀部
在你的胳膊下和腿上的皮肤褶皱里
在你的腹股沟
在你的乳房下面
您的皮肤可能会发痒或灼痛。 剥落的鳞片可能是白色或淡黄色，看起来潮湿或油腻。

因为脂溢性皮炎可能看起来像其他皮肤病，请去看医生以获得诊断和治疗计划
