IN Eternity Clinic is a luxury aesthetic clinic in Singapore on Orchard Road, founded by AYA and led by Medical Director and international Key Opinion Leader Dr Sin Yong. From non-surgical facelift and HIFU Singapore to acne scar treatment, body contouring and dermal fillers — every treatment is an act of restoration, returning you to your most timeless self with natural results and no downtime.
IN Eternity Clinic was founded by AYA with a singular vision: a Singapore aesthetic destination where artistry, medical rigour and genuine care meet. Every treatment at IN Eternity is led under the clinical direction of Dr Sin Yong, the clinic's Medical Director and an internationally recognised Key Opinion Leader.
As Medical Director, Dr Sin Yong brings together more than 15 years of medical and aesthetic expertise, trained extensively in Plastics, ENT and Anaesthesia at the National University of Singapore. He holds dual Masters degrees in Aesthetic Medicine (London) and Practical Dermatology (UK), with a distinction in his postgraduate diploma — and every signature treatment he has pioneered is available to patients at IN Eternity Clinic.
As an internationally acclaimed speaker and Key Opinion Leader for CLASSYS, DEKA, HIRONIC, FOTONA, ALMA, LUTRONIC and leading injectable brands, Dr Sin Yong has helped celebrities, athletes and discerning patients across Asia sculpt and restore their natural appearance — without the distortion of excessive filler or the risks of surgery.
Dr Sin Yong's signature non-surgical facelift protocol. Uses specialised laser energy to tighten sagging jowls, nasolabial folds and double chin — semi-surgical results with zero downtime.
A dual-energy non-surgical facelift combining volumetric radiofrequency and focused ultrasound. Targets the SMAS layer — the same tissue plane as surgical facelifts — for true vertical lifting without a scalpel.
High-definition body contouring that sculpts stubborn fat deposits, tightens loose skin and reveals muscular definition — delivering results that rival surgery without general anaesthetic or recovery time.
For patients who have experienced excessive filler treatment elsewhere. Dr Sin Yong safely dissolves and reshapes — restoring natural, youthful contours and correct facial proportion without distorting features.
A precision laser resurfacing protocol for acne and surgical scars — calibrated by scar type, depth and skin tone. Delivers measurable improvement with minimal downtime, for those who cannot afford prolonged recovery.
Dr Sin Yong's flagship scar protocol. Rebuilds severely scarred skin at the cellular level — energy depth, pulse duration and wavelength individually calibrated per scar, per patient. Permanent results.
A comprehensive multi-modal lifting protocol combining thread lift technology with energy-based devices to achieve superior vertical facial restoration. Designed for patients seeking a more definitive non-surgical result — the step before surgery.
These are the proprietary techniques Dr Sin Yong developed — protocols not found anywhere else, refined over 15 years of clinical practice and global teaching.
At our Orchard aesthetic clinic in Singapore, every journey begins with listening, not a treatment menu. Whether you are exploring a non-surgical facelift, acne scar treatment, HIFU or dermal fillers, the right protocol is the one shaped to your anatomy, your concerns and your life — nothing more, nothing less.
As Medical Director of IN Eternity Clinic and a Key Opinion Leader for 14+ global aesthetic brands, Dr Sin Yong regularly speaks at international summits, trains physicians across Asia and the Middle East, and leads live demonstration workshops from Singapore to Seoul to Dubai — bringing that same world-stage expertise to every patient at IN Eternity.
Celebrities, content creators and public figures across Singapore choose Dr Sin Yong for aesthetic outcomes that are natural, precise and effortlessly timeless.
All consultations are personally conducted by Dr Sin Yong. We recommend a 45–60 minute initial consultation to understand your concerns, discuss options, and build the right protocol for you — with no obligation.
