Eczema Dry Skin help

I'm 18 year old and i have had eczema/dry skin since i was born. My skin turns very dry, every time i wash my face, it goes rock hard and i have to use a moisturizer cream such as vaseline, in order to make my skin smoother. However after a few hours of vasline on my face, it starts to get dry and rough again, which makes my skin itchy and leads me scracth. Oh and also whenever i wake up in the morning, my face is so dry that i can see white dry patches on my face

i did homeopathy treatment twice. First time was when i was 11. I did it for around a year, but the results were the same, so i stopped. I then decided to do homeopathic treatment again, which was 2 years ago from another place, yet it still didnt make any differances, so i decided to stop.

At the moment i have eczema/dry skin on my face and my skin has thickened. Also i have noticed that the colour of my skin has become darker than before during the past few years, also sometimes it goes red on a few areas on my face due to scracthing. My skin colour on my face is more daker than compared to my arms, chest, legs.

what medicine can i take, in order to help me with my eczema/rough/dry skin and also helping me to bring back my natural skin colour on face, as it has turned into a darker shade.

Any help, advice and reccomendation, would be very much appreciated.

Thank you very much
