Sherin was absolutely amazing! I came in for under-eye filler and was feeling a bit nervous, but she made the entire process seamless. She took the time to explain everything clearly, which really helped put me at ease. I didn’t feel any pain at all, and she checked in with me throughout the procedure to make sure I was comfortable. Sherin was incredibly gentle and thoughtful—truly one of the best experiences I’ve had!

Great spot for micro-treatments! If you’re interested in adding to your beauty routine, but don’t want to go too crazy with it, this is it. I can vouch for their micro Botox – I’ve been going there for a few years now, every 3 months (really depends on how quickly your body processes the Botox; I have friends that only have to go every 6), and would never go somewhere else.

I had a really good experience with Monica today. She spent significant time reviewing my history and discussing options. Then we aligned on a treatment plan. From there she was patient and caring to ensure I felt comfortable throughout the session. Really glad I went to see the flat iron location – it renewed my faith with alchemy!
