I had my first experience with dermal fillers a couple of years ago, when I went to a med spa for Botox to treat my glabeller “11s” because I was tired of being told I looked “angry” when I wasn’t. While the spa was run by a licensed physician, I didn’t find out until I got there that a nurse does the injections. I was told that observable results could take up to four weeks. Ultimately, I didn’t end up with any kind of result, so never went back. I don’t know if the product was diluted, the nurse unskilled, and/or Botox just wasn’t the right product for me. I eventually went to a different med spa and had good results with Juvederm administered by a licensed physician.
