Can I get Botox in my upper lip a second time? I only got it done a month ago, but I didn’t see results.

Thank you for sharing your question regarding your recent Botox experience. I recommend following up with your injector who preformed your initial treatment to discuss your concerns. He/she should be a reliable resource for you before, during, and after your treatment. As you may already know, Botox can take up to 10 days to fully take effect. Since you have waited a full 4 weeks, you can certainly return to your injector for assessment. Such a small amount of Botox is used to treat the upper lip that is completely safe to add additional units. Best of luck, Dr. Kian. 

This is difficult to answer without pictures, but if you didn't get your desired results with Botox, you can get a touch up. Botox results take 1-2 weeks. See an expert. Best, Dr. Emer

Yes, you can get touch ups if needed. You may not have had sufficient amount or the placement might have been off. Either way you can revisit with whoever did the procedure to have things corrected.
