Does anyone have a quick remedy to fix dry skin?

I have a scab on my face under my lower right lip. The scar tissue is thick and unfortunately, gets picked on a lot by me. Also, I have really dry skin on my face. I've been under a lot of stress over the past year and feel that this has contributed to my dry skin and activated my complexion. I don't have the financial resources to afford skin care solutions to take care of the dry skin or the dark circles forming under my eyes. Does anyone have any basic at home remedies that I can make with products from my cabinet or refridgerator to fix this problem?
