If you have bags, of what I picture, almost like a mouse after a fight, that is water/fluid retention. Matryxl will not do much for that. Your gonna want a a good eye cream with caffeine for increased blood flow, and some other good ingredients. A micro-current treatment just around the eyes would be even better for draining the lymph. You might need multiple treatments but results will be visible after first treatment...UNLESS it has been there for to long. After to long fat will deposit in those pockets then it is surgery time.
What kind of acne scars? Flat? Discolored? Raised like a keloid? For all of the above chemical peel is the best, cheapest way to go. It`s not gonna do anything for stretch marks except burn your $$
Matryxl is a "plumper", similar to hyaluronic acid. When injecting you will not see full effect of the plump till after swelling goes down.
