Evolence is collagen-based dermal filler used for the correction of wrinkles, nasolabial folds, scars, skin grafts and other surgically-induced irregularities or soft tissue defects or deficiencies. The procedure begins with the application of a topical anesthetic agent to reduce discomfort. The injection locations on the face are marked and the Evolence is injected. Since Evolence gel is thicker than most other dermal fillers, a larger needle is used for the treatment.The amount of Evolence used in each treatment depends on the patient's desired results.
