“For years I struggled with my self-confidence when it came to my lips, but I always had too much anxiety to ever do anything about it. The moment I sat in Sari’s chair, she completely fixed both of those problems! She eased any anxiety I had and made me feel beautiful once again!”

“Sari is simply THE BEST! Her attention to detail and holistic approach to aesthetics is so refreshing and makes you feel 100% confident every step of the way. She has an astounding wealth of knowledge and expertise in aesthetics/injectables, which is apparent from the first few moments of the consultation. Sari does exactly that with her minimalist injecting approach and expert technique. She is truly a wizard, and I trust no one else with my face!”
