A second opinion is an assessment of what is there now, for anyone who has had filler, HIFU, laser, threads or botulinum toxin elsewhere and wants a doctor to look again. Dr Sin Yong takes the history, examines the area, uses ultrasound where it helps with filler, and sets out the options, which include waiting and doing nothing. It is not a review of another clinic's work, and urgent signs go to a doctor or A&E first.

A second opinion is a doctor's independent assessment of the result and the options, given by someone who did not do the original treatment. For most people the question is simple: is this how it is meant to look, is it still settling, and is there anything that should be done. Dr Sin Yong answers it from examination of the area in front of him, and the same assessment applies whether the treatment was done in Singapore or overseas.
It is not a review of another clinic's work, and it does not rank clinics. The Singapore Medical Council's ethical code asks doctors not to make gratuitous or unsustainable comments about colleagues that could undermine patients' trust, and this practice works the same way. What you will be told is what is found: where the product or the effect sits, how the tissue is behaving, and what can reasonably be done about it.
Many patients who come to Dr Sin Yong for a second opinion tell him they have tried almost everything else and had given up hope. Having tried other treatments does not mean nothing more can be done: what is done next depends on what the examination and, for filler, the scan show.
That history is useful. Knowing what was done, when, and what has already been tried often explains why a problem has stayed. With filler, hyaluronidase acts only on hyaluronic acid and only where it reaches, some fillers are not hyaluronic acid at all, and swelling can look like filler; ultrasound helps show which applies. For material that cannot be dissolved, Dr Sin Yong uses the Sculpting mode of Time Freeze Laser LCLR® for nodules large and small, without an incision. How each person responds varies.
If you have been told nothing more can be done, a review can help show what is there now, and the plan is made from that. More on filler that has stayed after dissolving is in when filler dissolving has not worked.
It suits anyone with a concern after treatment elsewhere. Common reasons are filler that looks heavy, puffy or lumpy, or has moved, which is the territory of the filler correction page and the pillow face page; HIFU or radiofrequency that did not do what was expected; laser treatment followed by darker or uneven skin; threads that are felt, visible or uncomfortable; and botulinum toxin that has left the face looking unbalanced. It also suits people who have been offered a plan and are unsure whether it addresses the actual problem.
Some people are better served by waiting. Recently injected filler often looks worse in the first weeks than it will settle to, and dissolving too early can mean treating a picture that was about to change. Swelling, fluid and weight change can also mimic excess product. If time is likely to help, you will be told so, with a point at which to review again. That is a legitimate outcome, as is being told that nothing needs to be done.
Warning signs do not wait. If the skin has turned white, dusky or mottled after filler, or if pain is severe or worsening, the right step is urgent assessment by the doctor who injected you, or at A&E, now; for any change in vision or eye pain, call 995 now, as set out further down this page and on the complication care page.
“Nobody wakes up overfilled. It arrives one reasonable appointment at a time.”
Dr Sin YongOn how overfilling builds up
The review begins with history: what was done, roughly when, what concerns you, what has changed since, your general health and medicines, and how your skin has responded to treatment before. The area is then examined at rest and in movement, in a light and at the angles that show what is happening, with palpation for depth, firmness and edges where filler is the question.
Where it helps, ultrasound is used to see where existing filler sits and at what depth, so that any decision is directed at the product rather than guessed at. Photographs may be taken for your medical record and planning, with your consent; they are used to compare like with like at review and are not used to advertise. For other treatments, the assessment covers the tissue, the skin response and what the original aim may have been.
You are then given the findings and the realistic options in plain language, including what each can and cannot do, the risks, and what no treatment would mean. Any plan is written down with the product or platform, the order and the review, and the fee is set out before consent is taken. You are not expected to decide on the day, and the consultation process page sets out the sequence in full.
Bring whatever you have: the product name, the areas treated and the dates, any receipt, aftercare sheet or messages from the clinic, a list of your medicines and supplements, and photographs of how you looked before the treatment, or five to ten years ago as a reference. Knowing what is there changes what can be done, and that is true of fillers above all, because only hyaluronic acid filler can be dissolved.
If you do not know what was injected, or the treatment was done overseas, the assessment proceeds the same way, without a lecture. You can also ask the treating clinic for a copy of your treatment record; doctors in Singapore are expected to keep clear records that support continuing care. A written list of what worries you most is useful, as is a note of what you would accept as a good outcome.
Findings are described, and the people or places behind them are not judged. You will hear where filler sits, whether a lump feels like product or like inflammation, how a laser response looks, or how a thread sits in the tissue. You will not hear a verdict on the other doctor, a comparison of clinics, or a promise about what could have been done differently.
You will also not be pushed into treatment. The assessment can end with advice to wait, to do nothing, or to see a dermatologist or a plastic surgery specialist, and where the right answer is more product, fewer products or a different approach, it is explained with its limits. Adding more filler over old filler without knowing what is already there is the most common way corrections go wrong, which is why mapping what exists comes first.
A second opinion also has limits, and they are worth stating. It cannot dissolve filler that is not hyaluronic acid, because calcium hydroxylapatite, polycaprolactone and poly-L-lactic acid do not respond to hyaluronidase; Dr Sin Yong treats lumps from those with the Sculpting mode of Time Freeze Laser LCLR®, without an incision. It cannot say with certainty which product is present if there are no records, although examination and ultrasound can describe where material sits and how it behaves. And it cannot predict how a recent treatment will finally settle, which is why waiting with a planned review is sometimes the correct advice.
Seek urgent care for any change in vision, eye pain or signs of a stroke: call 995 now, and do not travel to a clinic first. Difficulty breathing, a tight throat, swelling of the tongue or throat, or swelling that spreads quickly across the face, after any injection, including hyaluronidase, can be a serious allergic reaction: call 995 now. Itch, hives or swelling that spreads beyond the treated area: contact the clinic that injected you the same day. After filler, skin that turns white, dusky or mottled, or pain that is severe or getting worse, needs urgent assessment by the doctor who injected you, or at A&E, now.
After laser, thick yellow or oozing crusts, blisters, or pain, swelling and warmth that are increasing rather than settling need a doctor the same day; if no doctor can see you today, A&E. After botulinum toxin, a drooping eyelid or heavy brow should be reported, and difficulty swallowing, speaking or breathing is an emergency: call 995 now. Fever, pus or severe pain at any treatment site needs a doctor the same day; if no doctor can see you today, A&E. Spreading redness with a fever, or feeling faint, confused or very unwell: call 995 or go to A&E now. The complication care page lists these signs; urgent signs never wait for a message reply.
The consultation is a medical visit and carries its own fee, which is stated when you book; it does not oblige you to proceed. Singapore's rules prevent clinics from advertising prices, so this page gives no figures. Any treatment that follows is quoted in writing after assessment, never before.
What moves a treatment fee is the area or zones involved, what the assessment finds, which product or device is proposed and how much of it is needed, whether more than one approach is combined, and how the plan is staged. Where the right answer is to wait or to do nothing, there is no treatment fee at all. How quotes are built is set out on the how fees are quoted page.
Not for emergencies. A change in vision or eye pain after filler: call 995 now. Pale, dusky or mottled skin, or pain that is getting worse: go now to the doctor who injected you, or to A&E. Do not message or book for these signs.

WhatsApp Dr Sin Yong →or use the enquiry formYes. Dr Sin Yong assesses filler, HIFU, laser, thread and botulinum toxin concerns after treatment elsewhere, in Singapore or overseas. The review starts with your history and an examination, and you leave with the findings and the options, including waiting.
No. Findings are described, such as where filler sits or how the skin is behaving, without judging the doctor or clinic. The aim is to establish what is there now and what can sensibly be done about it.
The assessment proceeds anyway. Examination, and ultrasound where it helps, can show where filler sits and how it is behaving. Bring any receipt or aftercare sheet, and you can ask the treating clinic for your record.
Not unless you want to be and treatment is suitable. You are not expected to decide at the first visit, and you can take the written plan away. Waiting or doing nothing can be the correct advice.
The consultation carries a fee stated when you book, and Singapore rules prevent advertising prices. Any treatment fee depends on the area, the assessment findings, the product or device, any combination and how the plan is staged, and is given in writing.
It is worth it when something looks or feels different from what you expected, or when you are unsure about a plan. It can confirm that nothing is wrong, that waiting is right, or that something needs correcting, before any money or product is added.
Do not wait for an appointment. White or mottled skin and worsening pain need urgent assessment by the doctor who injected you, or at A&E, now, and for any change in vision or eye pain, call 995 now.
