Fat grafting can help to improve scars
Fat grafting beneath scars and damaged skin (after radiation treatments, for example) has been observed to improve overlying scar quality. Fat can also provide volume beneath a scar when it is released from its underlying attatchments.
Injecting fat into scar tissue
Although it is possible to inject fat into scar tissue this procedure must be performed very very carefully. Keep in mind that this scar tissue is not normal tissue. It has much more fibrous connections and may not have the blood supply as other normal areas of your body. For this reason, the amount of fat that can safely be injected is limited and a good result may require several sessions. Your best bet is to work with a board-certified plastic surgeon who is a great deal of experience with fat injection and scar revision techniques.
Fat grafting for scars
Fat grafting is a srugical technique of transferring fat.
You can make the analogy of trans"planting" a plant. Survival of the transferred plant depends on the health of the plant as well as the suitability of the area to which it is transferred. This means that a plant moved to a desert is less likely to survive than a plant transferred to a lush, fertile, moist, sunny environment.
The same goes for fat. Fat survives better when it is handled delicately, and then moved to a vascular (good blood supply) recipient site. Therefore the more the blood supply, the better the survival. Muscle has some of the best blood supply and fat does best when transferred to muscle. We use this principle when transferring fat to the buttocks. It does best when we implant it in the musclse of the buttocks.
Scar tissue often has a poor blood supply and may be stiff or resistant to enlargement. Fat garfting can help to eliminate depressed scars but the survival of fat in scars is generally suboptimal. However, when it works, it can be a very good result. Therefore it may be worth a try in many instances where a depressed scar is the primary priblem.

Fat injection for scars
Scars that are sunken (depressed) may benefit from fat grafting. An example of this is acne scars. It is important sometimes to release the scars (subcision) before injection the fat.
Fat grafting limited help for most scrars
Depressed scars in my experience benefit more by scar revision and re-arrangement. Fat grafting is of limited utility in most scars.
