Lines on the forehead after Botox: what to know

Botox is a brand name commonly used for injections containing botulinum toxin. These injections temporarily reduce activity in selected muscles, so they are most useful for expression-related [Wrinkles](/symptoms/wrinkles/). A crease that has become etched into the skin may remain even when movement is reduced.

The result can also look uneven if neighbouring muscles continue to move, if the forehead and brow need balanced assessment, or if the review occurs before the clinician expects the effect to settle. Different products contain different formulations, so do not compare doses or schedules without professional advice. [Botulinum Toxin Type A](/materials/botulinum-toxin-type-a/) is one material used in this treatment category.

Contact the treating clinician for a review rather than requesting extra injections immediately. Bring the treatment date, product information if available, and photographs showing the forehead at rest and during expression. The clinician may assess muscle activity, brow position and skin quality before deciding whether to observe, adjust a future plan or discuss another option.

Do not massage injection sites forcefully or use another aesthetic treatment without checking compatibility. [Dermal Fillers](/treatments/injectables/dermal-fillers/) work through a different mechanism and are not automatically suitable for forehead lines. Treatment around the eyes, including [Crow's Feet](/conditions/crows-feet/), also needs separate planning.

Seek urgent medical help for trouble breathing or swallowing, widespread weakness, severe allergic symptoms, sudden vision change, or a rapidly worsening severe headache after an injection. Contact the provider promptly for marked eyelid or brow drooping, increasing pain, spreading redness, pus or fever.

Ask whether the remaining lines are caused by movement or established skin texture, when a review is appropriate, and whether the forehead balance has been assessed. Confirm the exact product used, possible side effects, aftercare, and which alternatives should be avoided or considered.
