Our story

Thirty years of mastery
One unwavering standard

Rassapoom Clinic was founded on a single conviction: that aesthetic medicine, done right, should make you look like a better version of yourself never someone else.
That belief has guided every procedure, every patient, and every physician we’ve trained since 1994.
Our philosophy

From Structure to Skin
the art behind every result

At Rassapoom, we believe that beautiful results begin beneath the surface. Before any procedure, our physicians study the patient’s facial architecture bone, fat pads, muscle, and skin and design a treatment plan from the foundation up.

This structural philosophy is what separates a result that looks natural from one that looks done. We don’t follow trends. We follow anatomy.

Every patient who leaves our clinic should look like themselves — refreshed, rested, more confident. Never overfilled. Never frozen. Never like someone else.
Our journey

Thirty years
a few defining moments

1994

Founded Sukhumvit 49

Dr. Rassapoom opens the first Rassapoom Clinic on Sukhumvit 49, Bangkok. A single room. A singular vision: precision aesthetic medicine for patients who want natural results.
2005

Triangular Face Lift technique developed

Dr. Rassapoom develops and refines the Triangular Face Lift — a structural filler placement technique based on the golden ratio of facial anatomy. It becomes the clinic’s signature procedure and is later taught globally.
2012

Named Thailand’s Global Allergan Trainer

Dr. Rassapoom becomes Thailand’s only Global Allergan Trainer — the highest international qualification for Juvederm filler technique. He begins training aesthetic physicians across Asia and Europe.
2016

RMI Institute founded

The Rassapoom Medical Institute (RMI) is established — a formal training academy for aesthetic physicians. RMI has since certified hundreds of doctors in advanced injection and lifting techniques.
2019–2022

Expansion 5 branches across Bangkok

Rassapoom expands to Rama 2, Nonthaburi, Thawi Watthana and Liab Duan Ramintra bringing the same clinical standard to patients across all districts of Bangkok and Greater Bangkok.
Today

Thailand’s leading structural aesthetic clinic

10,000+ patients. 65+ treatment programs. 4 branches. One standard — the most natural result is the best result.

What we stand for

The values behind every procedure

Safety above all

Only Thai FDA-approved products. Only board-certified physicians performing procedures. No exceptions, no compromises — ever.

Honesty in every consultation

We tell patients what will help them — and what won’t. We never oversell. If a treatment isn’t right for you, we say so. Trust is built one honest conversation at a time.

Natural results, always

Our goal is not transformation — it is refinement. You should leave looking like the best version of yourself, not a different person entirely.

Continuous learning

Medicine advances. So do we. Our physicians train regularly on new techniques, new products, and new evidence — and pass that knowledge to patients through better outcomes.

Patient first, always

Every decision — from product selection to technique choice — starts with one question: what is best for this patient? Not what is fastest, most profitable, or most popular.

Teaching the next generation

Through RMI Institute, we train and certify aesthetic physicians — so that the structural philosophy that defines Rassapoom spreads to benefit more patients worldwide.
