There are natural and synthetic fillers. According to Dr Ng Hong Yi, medical doctor at Astique The Aesthetic Clinic, “Hyaluronic acid fillers are considered natural fillers and can last six to 12 months in the skin, while poly-L-lactic acid and calcium hydroxyapatite are synthetic fillers that can last one to two years.” The results for hyaluronic acid fillers are instant.
According to Dr Rachel Lim, medical director of Ardmore Aesthetic Clinic, hyaluronic acid acts as a water reservoir in the skin, drawing moisture to dehydrated areas. This leaves your skin smoother and more supple, and plumps up fine lines.
Poly-L-lactic acid is meant to stimulate collagen production, and requires three to five rounds over six months or more to see the full results.
Calcium hydroxylapatite is the heaviest of all dermal fillers and is used to fill moderate to severe creases and deep wrinkles, such as nasolabial folds and marionette lines, explains Dr Low Chai Ling, medical director of The Sloane Clinic.
Nasolabial folds, commonly known as “smile lines”, run from each side of the nose to the corners of the mouth. Marionette lines are the creases that run from the sides of your mouth to your chin.
