I have been going here for almost the past year, for eyelash extensions and Botox. I always booked with the same girl, you can tell the difference in work when they are finished. I have been to other places not as great and they fell off quicker. You need maintain the extensions which gets tiring. They are always booked so schedule your refills when you are there.
I had one bad experience with a newer girl who did lashes, I came in within 2 weeks of my prior appointment to get a refill, she stated that extensions were clumpy and she has to start over as a full set but wouldn't charge me as full but a refill. The maximum refill limit is usually 21 days by standard, when she said that and asked if I've been there before (over 15 times!) I was pretty insulted.
As for the Botox, they use the sister product dysport. It achieved the job, but I prefer Botox. The doctor comes in ones a month, very friendly and experienced woman who took her time to look at my my face and did not overwhelm with my telling me I needed more or upsell, very professional! I would recommend her.
