Aloe vera. Twice a day, I head out and cut up the unsuspecting plant, and then split it into halves and apply it to my skin and scratches. It's antibacterial, makes scarring less likely and promotes healing. Haven't needed chapstick in centuries, due to the unholy superpowers of this gooey druid plant.
Dermatologists will try and make a gold mine out of you. Seriously, just buy the fucking plant and smear it over your face. Hire some balloons and throw your skin troubles a Going Away Party, while you're at it, because they won't be back.
