Are there people who regularly get Botox for skin (wrinkles)?

They say domestic products develop resistance, is that really true? I have been getting domestic Botox Reztocin every four months, and I need to get it once more this month. I plan to get Reztocin again, but during the consultation, I was told that domestic products can cause resistance, so after about two treatments, it's better to switch to Jeomin for the third. I'm confused about what to do.

There is a big price difference between domestic and imported products.

So I'm even more worried now... I saw effects from Rizotoksin too~ If anyone has been consistently getting wrinkle Botox, please share your reviews~
