Sculptra is a product that is injected into areas where patients have lost volume, including bone, fat, and collagen. It causes your body to produce more collagen, thereby "volumizing" areas. It is typically injected in areas such as the temples, cheeks, and many other areas. We know that sagging skin and wrinkles are primarily the result of volume loss as we age; therefore, Sculptra helps to regain what has been lost. When volume is added to the face, your skin is supported again like is was when you were younger. Saggy skin and wrinkles are significantly improved. If you simply tighten your skin with lasers or a facelift, your skin is tighter, but you will still have the facial structure or "volume" of someone much older. Volume is the key to a youthful appearance. Best of luck to you.
