Hi there! I got Botox just about three weeks ago. At the two week mark, I had one Spock brow and one brow drop. I went in to have them touched up - the injector put 2 units right above my brow, but toward the end. Now I have brow drop in that brow too. I'm so sad/bummed. My question is, will the two lighten up at different times? Im hoping that they will start to correct themselves within the 4-6 week mark, but afraid that I'll have to wait longer on the most recent side. Is this what I should expect?
