What lip filler is for
Good lip work is about more than size. Small amounts of gel are placed for definition, balance and hydration. The plan starts with your own lip shape and how it sits in the rest of your face.
Several things shape how lips look: proportion, projection, the cupid's bow, the ratio of upper to lower lip, how crisp the border is, hydration and texture. Border definition and hydration often matter more than volume. So the question is not how much filler to use. It is which of these factors needs attention, if any.
Dr Sin Yong performs each treatment himself. He looks at lip anatomy, proportion, skin quality and your goals before any product is placed. A plan with no injection is a valid outcome. If you have had filler before and do not know what it was, this needs assessment, and ultrasound may be used.
Lip filler in Singapore: who it may suit
You want a modest change that stays in proportion.
Height, volume or projection differ a little between sides.

Hydration is part of the goal.
The lips have thinned with time.
You understand that swelling and bruising are expected.
Where the gel goes, and why
| Area | What it targets |
|---|---|
| Vermilion border | Definition of the lip outline |
| Body of the lip | Volume |
| Cupid's bow | Shape at the centre of the upper lip |
| Corners | Treated in some cases, for shape where the lips meet |
| Lip surface | Ultra-fine hyaluronic acid may be used for hydration and smoothness |
How a session runs
Who should wait or avoid it
Treatment waits.
An active cold sore, infection or inflamed skin around the mouth.
A known allergy to hyaluronic acid or lidocaine.
A bleeding disorder, or blood thinners that have not been reviewed.
An active condition needs thought first.
Filler of unknown type in the same area is a reason for caution, and it is assessed before anything is added.
Wanting a lip shape far from your own, or expecting filler to treat laxity.
What lip filler cannot do
It does not firm the skin around the mouth.
Lines caused by muscle action are outside what filler does.
It works with the lip you have. The aim is your own lips, in proportion.
Volume is only part of the plan, and more is not always the answer.
Swelling, bruising and uneven healing can happen whatever the plan.
Filler breaks down, so keeping the effect means more treatment, discussed at review.
Risks to weigh up
Swelling, tenderness, small bruises and firmness
Lumps, asymmetry, a cold sore flare in susceptible people, and an overfilled look
Blood vessel blockage or compression, which is an emergency, and a delayed inflammatory reaction
Warning signs
Seek help if skin turns white, grey, blue or mottled, or if pain is severe or getting worse. Any change in vision means going to emergency care. Also get reviewed for lips that are hot, red and more swollen, for fever, or for a hard, tender lump that appears later. Our page on filler warning signs explains why these matter. Hyaluronidase can dissolve hyaluronic acid if needed. Lumps or inflammation after unknown filler, and lip changes that look like a skin condition, are referred to dermatology. Do not wait for a routine review if any of these appear.
Recovery and aftercare
Swelling and mild bruising are common and usually settle over the following days. In the first 24 hours, do not press your lips. A cool compress helps, and it is wise to skip exercise, heat and alcohol. In the first week, keep your lips moisturised and avoid dental work and facial treatments unless cleared. Stay away from very hot food and drink. Avoid strong sun and heat, use sun protection, and restart active skincare once tenderness settles. The final result is judged after swelling settles. No duration can be promised, and it depends on the product, the amount and your metabolism. Lips move a great deal, so filler here breaks down faster than in less mobile areas. Results vary.
Judging the result
Swelling can make lips look uneven, so the final result is judged at review and not on the day. Uneven healing is a known downside, and so is the possible need for repeat treatment. Dissolving with hyaluronidase is possible at any point, but it is a further procedure, which is worth weighing before you start. Repeat treatment is discussed at review, not set in advance.
How fees are set
Fees are not published. The written quote depends on the amount and type of gel, how many lip areas are treated, whether earlier filler needs assessment, and any combined treatment. See how we quote and our filler aftercare page. A no-treatment outcome is possible.
