The clinic itself was faultless on hygiene, and my surgeon was great
Our Bookimed coordinator was excellent and empathetic; we knew what we wanted and appreciated not being pressured into extra treatments. This was so important. In contrast, the hospital's own liaison made numerous mistakes with transport and pricing, which could be stressful if you aren’t proactive in communication. The clinic itself was faultless on hygiene, and my surgeon was great. I received a silicone chin implant through an external incision under the chin. The aftercare guide was clear, but I was left wondering what to expect a month from now. My advice is to confirm your exact costs to avoid potential overcharges.
Our coordinator was excellent, empathise and timely in his responses. He came back to us with answers within 24 hours each time. He sent links to our surgeons and the hospital site. We knew we could rely open him, not be dismissed, nor ( other companies), be hard sold and pressured to buy add-on extra surgical treatments. This last point is so important. We’d done our research, knew what we wanted and didn’t appreciate other companies we considered telling us we need full face lifts and pressure if us to spend double our budget.
The hospital we chose ( Bookimed gives you choices) is beautifully presented and prizes itself on hygiene standards which were faultless in my experience. The liaison contact from the hospital, not associated with Bookimed made numerous mistakes and omissions related to transport pick ups, surgery procedures and pricing overcharging). If you’re not ahead in communication, anticipating questions, and have your exact costs due, then you may find the experience stressful.

My experience was mixed. My procedure covered the full face and neck under general anesthesia, and it's too early to see the outcome. I felt confident in my surgeon: I got a very good impression of my doctor Saran. The facility was also a very clean and modern clinic. The main challenge was communication; it's difficult to understand and get understood if you don’t speak Thai with the nurses, which felt a bit scary. Post-op contact has been minimal. The food was not good. Thankfully, no additional expenses.
I got a very good impression of my doctor Saran. I haven’t quite seen the final results yet because of swelling and bandages. Very clean and modern clinic
Difficult to understand and get understood if you don’t speak Thai with the nurses, their english is very poor. A bit scary since it’s important that there is no misunderstandings. Food was not good

the care provided by the surgeon and the staff was impeccable
My one-off operation went very well and the care provided by the surgeon and the staff was impeccable, apart from a few minor language issues. However, you should be prepared for a few additional costs that were not included in the original price: we had to pay for the transfers between the hotel and the clinic ourselves, and the wound care supplies were insufficient, which amounted to a mid-double-digit sum in total. My most important tip for future patients would be to make absolutely sure you clarify any dietary requirements (vegetarian/halal/...) with the clinic before you arrive.
The coordination team is very dedicated and always available. The staff are consistently very friendly and go out of their way to help. A very comprehensive package with extensive, thorough preliminary examinations and no hidden costs. A superbly equipped single room, including a sofa bed for an accompanying person.
Contrary to what was advertised, there was no interpreter. The nursing staff, in particular, did not always have a good enough command of English to explain everything clearly and in detail. The consultation with the surgeon was less detailed than expected. It wasn’t always entirely clear which services were included in the package and which weren’t (particularly transfers) – but there were no major hidden costs. Hospital food/light meals after operations are always a challenge, and perhaps even more so in a different cultural context – I wasn’t asked about any specific dietary preferences, so anyone who absolutely needs vegetarian, vegan, kosher or halal food should definitely clarify this in advance; in my opinion, the hospital bed was very hard, which is significantly more uncomfortable when you can’t move around much

My strongest feeling right now is one of being disappointed and scammed. The total costs nearly doubled, jumping from the $2000 USD Bookimed total to $5000 once I was at the clinic. The fractional CO2 laser treatment I received on my face and neck also wasn't what I originally requested; the doctor suggested changing it only after I had already arrived, which should have been communicated much earlier. While the clinic staff themselves were fine and have stayed in touch, the experience with the surgeon and the finances was poor. Make sure the treatment promised on Bookimed is the same one you're getting at the clinic. I would avoid this dermatologist and Wansiri.
The customer service at the clinic was great and the staff was very kind.
Patient Complaint Regarding Treatment Plan and Communication at Wansiri I am documenting my concerns regarding the communication, treatment planning, and services I received at Wansiri. Before my appointment, I specifically requested the following treatments: * Ablative CO2 laser treatment for the full face and décolletage * Ultherapy for the full face The estimated total cost discussed was approximately USD 2,000. The doctor agreed to this proposed treatment plan, and I confirmed that I wished to proceed based on that agreement. However, on the day of the scheduled treatment, the doctor informed me that she did not want to perform any CO2 laser treatment on my face. This was a significant change from the treatment plan that had previously been discussed and agreed upon. Instead, the doctor and coordinator recommended a different package consisting of: * Thermage treatment around the eyes * Ultherapy for the full face * Microneedling The revised package cost approximately USD 5,000, which was more than double the original estimate. My primary concerns were not adequately addressed. In particular: * No CO2 laser treatment was performed on my face. * No treatment was provided for my décolletage. * The crepey skin around my eyes, which was one of my main concerns, was not adequately addressed. * The treatment plan was substantially changed on the day of the procedure, after I had already traveled to and committed to receiving treatment at the clinic. * The reasons for changing the original treatment plan were not clearly explained before the appointment. * I was presented with considerably more expensive alternatives without adequate time to consider the change or seek another medical opinion. I relied on the doctor’s prior agreement when deciding to proceed with treatment at Wansiri. Had I been informed in advance that the doctor would not perform CO2 laser treatment on my face or décolletage, I could have reconsidered the appointment, consulted another provider, or made a more informed decision. As a result, I felt pressured into accepting a treatment package that was significantly more expensive than the original estimate and that did not adequately address the skin concerns for which I sought treatment. I left feeling that the communication had been misleading and that I had not received the treatment plan I had originally agreed to. I believe communication between the doctor, coordinator, and patient should be improved. Any changes to an agreed treatment plan, particularly changes involving substantially different procedures and costs, should be clearly communicated before the patient arrives for treatment. I am requesting a written explanation of: 1. Why the originally agreed CO2 laser treatment was declined on the day of treatment. 2. Why I was not informed of this change before the appointment. 3. Why no treatment was provided for my décolletage. 4. How the recommended treatments were intended to address the crepey skin around my eyes. 5. Why the final cost increased from approximately USD 2,000 to approximately USD 5,000. 6. What resolution or compensation the clinic proposes regarding the difference between the agreed treatment plan and the services ultimately provided.

The initial appearance is honestly better than expected, even with all the healing that’s still to come
The initial appearance is honestly better than expected, even with all the healing that’s still to come. Seeing that was a huge relief. The surgeon and staff provided great support, making me feel secure from the start. Recovery is no joke. It was a positive step when the catheter was removed, but managing the dilation sessions has been very challenging. My biggest concern is the swelling, and I'm focused on trusting the process. The care and the surgical foundation are solid, which is why I'm rating everything positively.
Everything was perfect. The staff were kind, professional, and very supportive throughout the whole process. The doctor explained everything clearly and made me feel comfortable and cared for. The clinic was clean, organized, and exceeded my expectations. I’m very happy with my experience and grateful for the excellent care I received.
Nothing to complain about. Everything went smoothly and I was satisfied with the overall experience.
