weird face skin at 20

Hi, I’m 20 and feel ugly because of my skin. I never had major acne issues. I started wearing sunscreen everyday a few months ago.

I don’t know how to fix my skin : I’m quite pale but still have an uneven skin tone, dark circles and overall dull looking skin that makes me look like i haven’t slept for a week and live on redbull and candy even though i don’t.

I wear skin makeup and feel pretty with it but it’s getting tiring not being able to do so when i’m bare faced. I feel like I have the skin of a 50 year old minus the wrinkles.

What do I do ?
