For people who have had breast augmentation and lift...?

I am 28 years old and about 100 pounds. My whole life I have had D breast which I hated! i have had 4 children and gained an enormous amount of weight with each, causing my breast to go from like EEE to totally deflated. I still have all the skin, but NO tissue! I am too young for this. I can't wear swimsuits or even shirts that show the slightest bit of cleavage because it's just wrinkled up skin. I am having a lift and augmentation soon, but have read there is a lot of scarring. Is there and does it fade? Is it worth it?
