Formation of nasolabial fold

Nasolabial folds—also known as smile lines, laugh lines, or nasogenian furrows—are the deep skin creases that extends from the corner of the nose to the corner of the mouth. This aesthetic issue forms as a result of biological aging, whereby the normal cellular production rate decreases rapidly. Besides that, some patients also undergo the loss of facial fat tissues, which causes the skin to become inelastic and sag even more. Furthermore, repetitive facial movements, such as smiling, lead to the further deepening of this skin groove. Though nasolabial folds may look attractive during facial expressions, they can still create an inaccurate impression of one’s age and outlook.

How does Restylane filler help to correct nasolabial folds?

Restylane is a renowned brand of cosmetic fillers that contains non-animal stabilized hyaluronic acid (NASHA) as its active ingredient. The hyaluronic acid molecules are extracted and purified via biofermentation before being cross-linked into a biphasic injectable gel. Restylane boasts a wide range of fillers that can correct various types of aesthetic imperfections, from a simple case of skin dehydration to severe volume and contour deficits. However, the filler that is best suited for correcting nasolabial folds adequately is Restylane Defyne, which was formerly called Emervel Deep. This completely biodegradable injectable medical device is made of 20mg/ml of NASHA and processed using Optimal Balance Technology. As a result, the gel has a lifting effect that can seamlessly integrate with the skin matrix to instantly erase deep dermal creases, such as nasolabial folds.

How is Restylane filler injected to correct nasolabial folds?

This filler is meant to be administered into the nasogenian furrow via deep dermis or subcutaneous injections. Patients are then left with firm skin and a smooth visage. The treatment session must be performed aseptically by trained physicians after their patients have been thoroughly assessed.

How long will the results last?

The exact duration of action varies depends on patients’ physiologies (health status, skin condition, age, lifestyle, etc.), the volume of filler material administered, and the injection technique employed. The manufacturer, Q-Med, claims that Restylane Defyne is able to correct nasolabial folds for up to a year before being completely biodegraded into the surrounding tissues. Once the skin-firming effects wear off, patients can obtain touch-up injections to retain their youthful appearance.  

What are the side effects of Restylane filler injections?

Following the aesthetic procedure, patients may experience some adverse injection site reactions, such as pain, tenderness, bruising, swelling, discoloration, and transient redness. These inflammatory reactions are mild and should subside within a few days with beneficial aftercare methods.

You can follow your doctor’s aftercare methods to speed up the recovery time. As well, some products are designed to help the skin heal itself after aesthetic treatments such as dermal fillers. That being said, Restylane is used world-wide and is considered a safe and effective treatment.

Is the filler integrated with anesthetic agent?

Yes, Restylane Defyne is only available with 0.3% lidocaine integrated into the filler gel. This fast-acting anesthetic agent minimizes discomfort and pain during the treatment session.
