What Is Lip Filler?
Lip filler involves the injection of hyaluronic acid (HA) gel into one or more parts of the lip — the body for volume, the vermilion border for definition, the cupid's bow for shape, and the Glogau-Klein points for projection. HA is reversible (dissolvable with hyaluronidase), safe and tailorable to specific lip architecture.
Natural vs. Overdone — The Difference
Natural results maintain the natural upper-to-lower lip ratio, respect the vermilion border, preserve the cupid's bow and do not overfill. Overdone results typically occur when too much volume is placed, filler is placed in the wrong planes, or volume has accumulated over multiple sessions. Dr Sin Yong's philosophy: lips that look like yours — only better.
How Long Does Lip Filler Last?
Typically 6–12 months, varying with metabolism, product and volume injected. Lips are one of the most mobile areas; filler metabolises faster here than elsewhere. Most patients schedule maintenance every 6–9 months.
The Procedure — What to Expect
Topical numbing cream is applied 20–30 minutes before. Most premium HA lip fillers contain lidocaine for additional comfort. Procedure takes approximately 30 minutes. Swelling peaks at 24–48 hours and resolves within a week; final results are visible at 7–10 days.
Choosing a Provider
The lip is technically demanding. Key considerations: Is the injector a licensed doctor with training in facial anatomy? Do their results look natural? Are they willing to use restraint? Can they dissolve filler if needed? Dr Sin Yong performs lip enhancement at Orchard Road.

Natural lip results require a specifically formulated lip filler, correct volumes (less is better for first-time patients), and attention to lip anatomy — Cupid's bow, philtrum columns and vermilion border, not just overall volume.
6–9 months for most HA lip fillers. Lips are a high-movement zone and metabolise filler faster than static areas.
Topical anaesthetic cream applied 20–30 minutes before the procedure significantly reduces discomfort. Most patients rate the experience as 3–5/10 with topical anaesthesia.
Yes — all HA lip fillers are dissolved with hyaluronidase within 24–48 hours. This reversibility is one reason HA is always preferred for the lips.
