Maybe it's because I've had Botox more than 10 times, but it doesn't seem to be as effective as before.

Try getting a higher dosage. They say you need a higher dose as you get older to see results. Also, for a domestic product that doesn't cause resistance, I recommend Coretox!

I also used to use a German product, but I switched to ReanTox because of the price, and the results are amazing lol. Since it's a premium toxin, the effects are great even if I get it regularly.
