For treatment of Eczema you should seek the uderlying cause first, but if you just want to give relief i suggest corticosteroids and anti histamines, you might add moisturizer too.
Go consult to your doctor.

I’m 18 years old & have had eczema since I was little, where it was so severe the doctors had to bandage me up from head to toe, as I grew up, it seemed to clear away however over the past year or so it has come back, mainly on my face, around my mouth and eyes. I’m studying my a levels and my confidence has gone totally. Ive been referred to the dermotology care at the hospital & they just discharged me after two appointments! I’ve tried at least 30 different medicines & creams but none seem to work. I’ve noticed that my skin clears when the weather is cold & gets worse when it’s hot. Does anyone else have this problem. I would really appreciate it if you could let me know of any treatments or anything you have done in order to get rid of excema. I just have no idea what to do anymore & it’s really getting me down. Thanks.

There are no cures for Eczema, only managements. Here are a list of dos and don’ts:

Things not to do:-

Don’t use biological powders
Don’t use fabric softeners
Don’t use soap or detergents to wash with
Don’t use standard shower gels or bath additives

Things to do :-

Try Fairy Snow -the old fashioned powder
Use dryer balls
Use a soap free cleanser to wash hands etc.
Use a moisturising shower gel like Oilatum
Use a moisture bath additive like Aveeno
Use a good moisturiser like Aveeno
Use it very frequently, you can’t over-moisturise!
Use antihistamines for itch, a non sedative one like loratidine in the morning and a sedative one such piriton at night.
You may need to use steroids creams/ointments for flare up areas. Use the mildest you can, for the shortest time possible.

Sorry if you knew all of that already
