Bad skin and bags under my eyes?

it could be a vitamin deficiency; a blood test from your doctor will tell you. if not, then the capillaries under your eyelids broke and the blood pooled under your skin. for reducing puffiness, you can chill spoons in your freezer for about 10-20 mins then hold them under your eyes. i would follow up with a good concealer and possibly an under eye brightener which has a slight shimmer. as for your back, the only thing that comes to mind is switching your bodywash to one that helps your acne. if youre skin is oily, id go with one that has silica in it to absorb the oil. also to treat the acne you could use a medicated one with benzoyl peroxide or salicylic acid, such as proactiv, acne free, skin id, etc. also keep in mind that alcohol dehydrates your skin, so the day after you party, you need to rehydrate =] good luck
