Try Revitol Eye Cream. I have used other expensive eye creams, but this is the winner. I have no eye irritation that i had using other creams. Dark circles also seemed to subside a little. I will recommend this amazing product. Click below for more info. http://goo.gl/udfyP
It would be advisable to visit a beauty shop, and they will tell you some of the best creams you may use to get rid of acne. They can tell the ones that cannot cause side effects. Examples are Egyptian magic creme, Palmers cocoa butter and Quantum Health Derma
Most of the answers above are referring you to acne products. As I understand your question you want to get rid of acne scars (not acne). If that is right, I agree that microdermabrasion is the best way to go. If the scars are not too deep you may need only a few (maybe 4-6) treatments. If they are deep acne scars, you will need more treatments. See an esthetician if your scars are not deep; if they're deep you may want to consult a dermatologist.
100% aloe Vera gel. It's cheap and works amazingly! Aloe vera will reduce redness, get rid of marks, and speed up any acne healing you have. Just wash your face like normal and then put a thin layer of the gel on your face. It will dry out your skin so I do recommend a moisturizer afterwards. Another way to get rid of any marks/ acne is by combining sea salt and hot water in a container. Let the mixture set for 15 minutes or so then pouring put any excess and putting some of the mixture on your marks for about 20 minutes then removing with a warm damp rag. Apply moisturizer after. Hope this helps(:
