I've been getting it every 6 months for about 5 years now, and my face has definitely gotten rounder than before~
At first, I mainly got it with Geomin because of my tolerance, but I mixed it with cheap domestic products and got it, but it doesn't seem to make much of a difference...?
My chewing muscles were originally big and my face wasn't pretty, but after getting botox, I don't think it will completely go back to how it was before even if I don't get it for a long time, and I'm recommending it to people around me~
