- Julesz D.★★★★★Jul 2026
This was my first time ever getting facial and lip fillers. Before making a decision, I spent a lot of time researching because there are so many aesthetic clinics in Bangkok—it feels like there’s one on every corner! I wanted to make sure I chose the right clinic. I’m so glad I chose Mega Clinic. Dr. Nattakrita was incredibly professional, listened to what I wanted, and delivered exactly the results I was hoping for. The enhancements look natural and beautifully done. I definitely made the right choice and will be returning for future treatments. Flying from Malaysia to Bangkok is easy and convenient, so it’s well worth the trip. Highly recommended!

I have already visited the rangsit branch multiple times so tried the Siam square branch today.. was really impressed! The staff were so kind, informative and friendly! There was a man working there who really took care of me and ensured I understood everything explaining all details really well. The doctor was also really sweet and ensured I had minimal pain for my procedures. I’m so happy once again with mega clinic and will continue to go to their clinics and recommend them. Five star experience highly recommend.
