Great experience.. as usual
I could not recommend Sisu Clinic more! Dr Salina was incredible. Very knowledgeable and gave a lot of advice according to my goals. What I like the most is that there is no ´sale pressure’ as we can see sometimes in other clinics. The results are always amazing and also super natural. I trust the team 100% for any of my treatment and won’t go anywhere else.
