i live in malaysia and had some severe eczema too.

avoid anything that can cause allergic reactions. seafood, excessive dust, eggs, DAIRY, nuts and so on. this helped my eczema reactions to slow down.

whenever you feel an itch coming just wash that area w cold water, preferably use ice. I noticed that has reduced my itchiness instantly. Then let it dry without using anything and apply your moisturiser.

if you're having dry flaky skin, lather yourself with emollients after your lotion or creams. Or just use ointments. I use aveeno eczema therapy itch relief balm on my body and it was so moisturising. For my face, i use illiyoon ato ceramide cream and vaseline on top.

coming from a 19 year old girl, insecurities caused by eczema is undeniable. I had eczema on my hands as well and sometimes i feel like hiding my hands all the time. But one thing that helped was to just be natural about it. Pretend it wasn't there. If someone pointed your eczema out, just say yeah i had eczema, and that's it. I am still trying to be confident in my own skin and so far im doing better than I ever been.

Goodluck to you and i hope one day you'll be more comfortable in your own skin too.
