Wrinkle fillers, also known as dermal fillers or facial soft tissue fillers, are approved by FDA for use in helping to create a smoother and/or fuller appearance in the face.
These products are used for correcting defects in the face, such as moderate to severe facial wrinkles and skin folds, lip and cheek augmentation, and to restore or correct the signs of facial fat loss in people with HIV.

Most dermal fillers injected into the skin have a temporary effect, because over time they are absorbed by the body. FDA has approved only one product made from a material that remains in the body and is not absorbed.

FDA has not approved dermal fillers for increasing breast or buttock size or for injections anywhere other than in the face.
FDA has not approved liquid silicone or silicone gel for injection to fill wrinkles or augment tissues anywhere in the body.
