There for acrylic with gel powder. It was super busy in there after work (unsurprisingly) and the technician specified on Treatwell wasn’t the one o got, but I must say the man who did my nails did a great job - really neat, thorough, did three coats to give even coverage without asking (a lot of people only do two). Not the worlds most relaxing experience but good for what you pay and good quality, I would return
