Dr Sin Yong

Dr Sin Yong is the Medical Director of IN Eternity Clinic. He graduated in medicine from the National University of Singapore and holds MRCS (Edinburgh), an MSc in Aesthetic Medicine from the University of London, an MSc in Practical Dermatology from Cardiff University, and a Graduate Diploma in Sports Medicine.

His clinical work centres on lasers and energy-based treatments, non-surgical lifting, acne and surgical scars, pigmentation, injectables and body contouring. He has developed several named protocols used at the clinic, including VF Lift – Vertical Facelift, Time Freeze Laser LCLR®, S3 resurfacing on the DEKA Tetra Pro, FSX Laser and the 4K Body Lift.

Consultations at IN Eternity Clinic are conducted by Dr Sin Yong personally. He examines, explains the options and their limits, and writes the plan; where a concern is better handled by another specialty, he says so and refers.

Beyond the clinic

International work with device makers

Dr Sin Yong is an International Key Opinion Leader for aesthetic device makers including CLASSYS, DEKA, Fotona, Hironic, Ilooda, Lutronic and Alma. In that role he has been invited to share his clinical expertise with fellow physicians at symposia and clinical meetings in Singapore and across Asia, including the CLASSYS APAC International Symposium in Bangkok in 2026.

A Key Opinion Leader role is a working relationship with a manufacturer’s clinical teams on how a platform performs on real skin; it is not an endorsement of a product for any individual patient. IN Eternity Clinic is also a designated DEKA Centre of Excellence.

Registration

How can I check a doctor’s registration in Singapore?

Every doctor practising in Singapore must be registered with the Singapore Medical Council. The SMC publishes a searchable register of medical practitioners on its website, where you can look up a doctor by name and see their registration details and the place of practice they have declared.

Dr Sin Yong is an aesthetic physician. His MSc in Practical Dermatology is a postgraduate qualification; it is different from being accredited as a specialist dermatologist in Singapore, and the clinic does not describe him as one.

Questions

Frequently asked questions

Who will see me at IN Eternity Clinic?

Consultations are conducted by Medical Director Dr Sin Yong. He examines you, explains the options and their limits, and writes the plan. If you have a preference about which doctor you see, mention it when booking. Consultations end with a written plan, and you can take time to consider it before booking any treatment.

Is Dr Sin Yong a dermatologist?

Dr Sin Yong is an aesthetic physician. He holds an MSc in Practical Dermatology from Cardiff University, which is a postgraduate qualification, but he is not described as a specialist dermatologist. Where a skin condition needs a specialist dermatologist, he will refer you.

How can I check a doctor’s registration?

The Singapore Medical Council publishes a searchable online register of medical practitioners. Search by the doctor’s name to see their registration details. Every doctor practising in Singapore must be registered. It is reasonable to ask a clinic who will perform your treatment and to check that person before you book.

What does International Key Opinion Leader mean?

It means a device manufacturer works with the doctor on how its platforms perform in clinical practice, and invites the doctor to share clinical expertise with other physicians at meetings and symposia. It is not a product endorsement for any individual patient.

Which languages are consultations in?

Consultations are conducted in English. If you would be more comfortable in another language, mention it when you book and the clinic will tell you what can be arranged. You are also welcome to bring a family member or friend to help with translation and to take part in the discussion.

How much does a consultation with the doctor cost?

The clinic will confirm the consultation fee when you book; it is waived if you go ahead with any medical treatment. Treatment fees depend on the concern, the area, the number of sessions and what is found on examination, and they are explained in writing after the consultation rather than quoted in advance.
