Sharp lines developed after first time Botox. Diagonal line from eyebrow to forehead. Deep and painful. (photo)

Thank you for sharing your question and photograph.  Due to some asymmetrical muscle paralysis you have developed some diagonal lines from the non-paralyzed forehead muscle moving.  Rest assured that you will return to your normal appearance in 3-4 months when the Botox wears off and will not have any permanent negative effects.  hang in there and interview new injectors.  

Sometimes certain lines will be more prominent after BOTOX while other lines are reduced. A refinement should be done to improve results as you age and continue treatment. You should always choose a physician who specializes in injecting BOTOX because treatments should be customized to your specific needs and those needs change over time. 

Unfortunately but honestly this is probably due to misplacement of Botox by an inexperienced injector. I would consult with another injector. Botox is a powerful tool for wrinkle reduction and when done right, it gives amazing results. You will likely only need a few units of Botox injected in the correct location to improve your result.

Botox is a great injection for forehead wrinkles.  Unfortunately, It looks as if the Botox migrated and was not put in the whole area.  You can return to your treated area to have a small amount of Botox placed in the area to correct it.  Please consult an expert for the best cosmetic results. Best, Dr. Green

Thank you for your question NellyN. Botox is a great treatment to address wrinkles associated with facial expression such as those on the forehead. Any time a patient does Botox for the first time, we always take standardized before photographs in five positions both at rest and with facial expression. Two weeks later we take the same series to assess the results. In this way, if the result is not ideal adjustments can be made. When treating the forehead, I like to treat the horizontal wrinkles on the upper forehead along with the frown lines between the brows. This allows for a harmonious balance on the forehead and decreases the possibility of appearance of new wrinkles. When new wrinkles appear with facial expression, a small amount of Botox can be used for correction. I always reassure patients that Botox is not permanent and results will last three to four months on average. Please consult with your doctor for specific recommendations. Good luck!
