Jiajia is very professional and a very nice person! She provides very precise and professional treatment plans to achieve the desired results. I go to my annual Ultherapy appointment and Botox session with Sai. She's always professional and extra sweet, always knows what's best for getting the results you desire and gets it done perfectly. I can see instant results after a couple of hours of the session; my face becomes more lifted and feels rejuvenated! I would highly recommend her!
