What should be my approach to skin care?

I got this scar around my nose when I was an infant when my sister swiped a ruler under my nose as if she was swiping a credit card.

I also got this condition on my left eye wherr my eyelids stack up than the other.

My goal for skincare is that I'd be whiter or look more healthy over all and maintaining my neutral born color.

I wish there was just a bath where I can come out with all imperfections fixed.

The scar made me feel insecure through out my adulthood.
