Restylane®, an injection for the correction of moderate to severe facial wrinkles and folds, such as nasolabial folds, the lines between the nose and mouth. Restylane is the first and only FDA-approved dermal filler made of a biodegradable non-animal stabilized hyaluronic acid (NASHA™). Hyaluronic acid is a natural substance found in all living organisms and provides volume and fullness to the skin.
Restylane is formulated as a clear gel and uses a dual mechanism of action to correct wrinkles and folds. Upon being injected beneath the skin's surface, the NASHA gel adds natural volume and lift to smooth wrinkles and folds. The NASHA gel integrates into dermal tissue then attracts and binds to water molecules to help maintain volume. Restylane is gradually degraded by the body's own mechanism and disappears without any residue. Results can be seen immediately following treatment and last six months, or even longer.
Restylane is the first and only dermal filler made of crystal-clear gel called NASHA (Non-Animal Stabilized Hyaluronic Acid). NASHA is developed using a unique stabilization process that results in its long duration of effect in contrast to non-stabilized hyaluronic acid, which lasts only days to weeks, at most. As opposed to other hyaluronic acid products, NASHA is not derived from animal sources. It is produced biotechnologically by natural fermentation in a sterile laboratory environment. This significantly diminishes the risk of transmitting diseases between species or of eliciting allergic reactions in patients who are sensitive to common foods, such as beef, chicken and eggs. NASHA has been extensively researched for over a decade and proven to be safe and effective. Restylane does not require any allergy or skin test prior to injection.
