Hyaluronic acid injections can be used as a dermal filler to improve the skin’s contour and reduce depressions in the skin due to scars, injury or lines.
Facial lines and features that can be corrected using hyaluronic acid implantation include:
- Frown lines that run between the eyebrows (glabellar lines)
- Smoker’s lines which are vertical lines on the mouth (perioral lines)
- Marionette lines at the corner of the mouth (oral commissures)
- Worry lines that run across the forehead (forehead lines)
- Crow’s feet at the corner of the eyes (periorbital lines)
- Deep smile lines that run from side of the nose to corners of the mouth (nasolabial furrows)
- Cheek depressions
- Redefining lip border
- Acne scars
- Some facial scars
Am I suitable for hyaluronic acid therapy?
Almost all people are suitable for hyaluronic acid therapy. Because hyaluronic acid is chemically identical within and between species, allergy to it is very rare.
How is hyaluronic acid treatment given?
Treatments are carried out at a medical center by a trained doctor or supervised nurse.
Procedure for hyaluronic acid treatments:
- The treatment area is wiped with an antiseptic.
- Local anaesthetic may be used to numb the treatment area.
- Injection method used depends on the doctor but will be either the serial intradermal puncture technique (series of small injections with a very fine needle) or tunnel or threading technique (needle is withdrawn as the hyaluronic acid is injected).
- Depending on the area treated, the skin may be lightly massaged.
- Immediately or within a few hours after injection the site may be red and swollen. This usually disappears within a week.
- Another one or two treatments (at least a week apart) may be necessary to achieve the desired correction.
How long do hyaluronic acid implants last?
Hyaluronic acid implantation is not permanent. Like natural hyaluronic acid, manufactured hyaluronic acid once injected into the skin will gradually break down and be absorbed by the body. In most cases, the augmentation usually lasts anywhere between 3-9 months. To maintain the initial results, repeat treatments or “top-up” treatments will be necessary.
Are there any side effects from hyaluronic acid therapy?
Hyaluronic acid therapy is generally very well tolerated. At the time of treatments most patients report minor discomfort. This is minimized by the use of a local anaesthetic. Immediately after treatment the area may be red, swollen and tender, this usually improves within a few days. Rarely, allergic reactions to hyaluronic acid have been reported. These are generally red and/or thickened nodules arising in the injected sites and may persist for several weeks or months.
