Dark marks on & around my nose making my skin look uneven and nose fatter and bent than it actually is. Want solution. (photo)

My face complexion overall has uneven and really dull skin tone, but one problem at a time. Wore suncream for nearly 2 years and dont wear glasses in public yet no difference. Dont know if its a tan, A whitish line going across my nose spreading to the side of the bridge. Before the line my nose is darker and after the line my nose skin is lighter (check pic with caption Recent (Diagram)) My lighter nose is also significantly lighter than the rest of my face giving it an uneven skin tone.
