WHAT PEOPLE SAY.
- 강지은★★★★★May 2026
I came here because I heard the doctor has amazing technique, and the results definitely speak for themselves. I got both Filler and Retuo, and the entire experience was fantastic!!! The doctor really took the time to map out exactly where the treatments should go to balance my proportions, rather than just doing a one-size-fits-all approach. The procedure itself was super comfortable with almost zero pain. It’s only been three days, but it has completely tightened and contoured my jawline. Friends are already asking me what I did because they say my face looks so much smaller! Highly recommend if you want natural but incredibly effective results.

I visited this clinic to have re2O done today and it was the most refreshing and amazing experience. I have gone to a few dermatology clinics during my stay in Korea for multiple procedures and this one is a place I want to return to! The staff are so friendly here and the chief doctor is very approachable and has an eye for aesthetics. She asked if I ever considered filler in my chin and to be honest all my focus had been on just one area of my face. She took great care in molding the filler until she was satisfied(I have a feeling she's a perfectionist) and even took my facial asymmetry into account. The results are so subtle but it surprised me at how chin filler would balance out my facial proportion and profile. Even the numbing cream was applied in a private area to rest while other clinics usually just have you sit out in the front lobby. I want to mention that everyone I encountered was so helpful and kind. Instead of being busily herded around with an expression of disdain on their face, their treatment was so attentive and sweet. I 100% want to recommend this clinic for any skin concerns and she is also apparently famous for being one of the best doctors to go to for lip filler.

This place doesn’t oversell you which is nice but that also means they don’t really recommend unless you ask specific questions. Got re2o and Botox. The doctor and staff are friendly and professional.

The consultation manager, the director, and the receptionists were all kind, so I was able to receive the consultation and procedure in a comfortable atmosphere. I am very satisfied because they made it look natural and beautiful without being excessive. They designed it to suit my face, so it looks natural without being awkward, and there was hardly any pain! I recommend this to anyone considering lip or chin fillers.
- Haseo★★★★★Sep 2026
I was concerned because my lips were asymmetrical, and my upper lip was thin with quite a few wrinkles. However, Director Kim Se-rae performed the procedure naturally, tailoring it to suit my face! To be honest, I booked and visited without much hesitation, having seen the clinic on Instagram. I didn't bring any specific photos of the lips I wanted to see, nor did I make many requests during the consultation. However, perhaps because the director has such a great sense of aesthetics, I've heard from many people around me that the lip filler turned out really naturally.🧡 What I like most is that it blends naturally with my face without looking overly artificial. I plan to stick with Say Clinic for my lip fillers from now on.💛 All the staff were kind, and I liked that the clinic itself was clean with a warm and comfortable atmosphere. Personally, I was even more satisfied because it didn't feel like a factory-style clinic at all!
