How do I moisturize severely dry skin?

I'm seriously in such a serious state these days. Sob sob 😭

I knew I had dry skin, but lately it's been extremely dry.

It is at that level, so the skin feels tight, cracked, and peeling.

It's total chaos.

My skin feels tight right after washing my face, and no matter how much cream I slather on, it gets dry and rough again after a while... and the bathroom too.

I don't eat at all, and I feel all fluttery. When I look in the mirror, I get so upset that all I can do is sigh.

I've tried all sorts of highly-rated moisturizing creams, serums, and oils, but I don't get that feeling of hydration deep inside.

It feels like it's just covered up on the outside, you know? So these days

I kept searching endlessly because I wondered if I was doing something wrong

I'm stuck in a swamp.

I even tried layering my moisturizers by going from toner to essence to serum to cream to oil, but after some time passes, it happens again.

It was exactly the same. ㅠㅠ But then I actually felt frustrated.

I even get breakouts sometimes.

If you have extremely dry skin like me and want to moisturize from within...

Does anyone know how to make this? Any routine or...

I'm really curious if you've tried the product, and I'm curious about how to use it or any tips. I also don't know how to manage dead skin cells.

I'm afraid that if I do it too often, it will get drier.

If anyone can recommend a routine or products that lock in moisture well, please leave a comment.

I'm seriously thinking about this, so I'm trying to change something. I would be so, so grateful for even the smallest tip.
