Restylane®
Dr. Park’s Approach:
“Fillers are wonderful adjuncts to the surgical procedures I perform. The manufacturers are continually bringing new products to market. Although some of these products do not appear to live up to their hype, many of them are safe, effective ways to improve the appearance of individual areas.
The most common fillers I am currently utilizing include Hyaluronic Acid fillers; common trade names include Restylane, Juvederm and Radiesse. For each patient, we determine the best material to use in each area. In some cases, we are looking for a deeper filler; other times the injection will be more superficial. There are some areas of the face that are inappropriate for certain materials. Longevity is always a concern.
For people with nasolabial folds, marionette lines, lip creases, cheek lines, hollowed hands and other areas which could use volume, fillers are a great option to improve the areas without surgery.”
What is Restylane?
Restylane is a FDA-approved dermal filler made of a biodegradable, non-animal stabilized Hyaluronic Acid, which is a natural substance found in all living organisms, providing volume and fullness to the skin.

Restylane is a gel of Hyaluronic Acid generated by Streptococcus species of bacteria. 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. Restylane does not require any allergy or skin test prior to injection.
Restylane is indicated for mid-to-deep dermal implantation for the correction of moderate to severe facial wrinkles and folds, such as nasolabial folds. Restylane is also indicated for submucosal implantation for lip augmentation in patients over the age of 21.
Restylane is formulated as a clear gel and uses a dual mechanism of action to correct moderate to severe wrinkles and folds. Upon being injected beneath the skin’s surface, Restylane 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 Restylane treatment and for up to six months. Some patients may achieve results that last longer than six months, depending upon injection site.
Restylane is also marketed and sold in more than 65 countries outside the United States where it has been used in more than ten million procedures.
