Best alternative to Botox? Microneedling good for wrinkles on the forehead and old scars?

I just received botox. And while I'm happy with the results, I'm scared to do it again in three months. I felt ill for the first week and I had a slight droop. (I've seen worse though and you can't really tell). I'm trying to read what the next best thing would be for my forehead and in between the nose...but there is so much info. I have a tummy tuck scar that is still really red (2 1/2 years post op) and wrinkles on the forehead. Can anyone help??
