Loss of collagen with ageing leads to thinning and sagging of the skin, causing wrinkles and deep lines to appear. Fat tissue which maintains the fullness of the face can also be lost, leading to hollowing of the cheeks and of the area under the eyelids, accentuating the appearance of eye bags. Hollowing of the temples also add up to a more gaunt and aged appearance. A natural collagen stimulator called Sculptra™ can be injected into the skin to help to smoothe deep lines and wrinkles as well as replace lost volume, leading to natural-looking, fuller face. The overall effect is a more youthful appearance with gradual, natural-looking results.
