What should you know about Botox's original use?

Botulinum toxin blocks signals between nerves and muscles at the treated site. This can reduce unwanted muscle contraction for a period of time. In aesthetic care, the goal is usually to soften lines formed by repeated expression, such as frown lines or crow's feet. The treatment does not remove every wrinkle and does not restore volume or change the structure of the skin.

The medical history explains the mechanism, but it does not decide whether cosmetic treatment suits you. Injection location, dose, facial anatomy, existing asymmetry, and the clinician's technique influence the result. A consultation should cover both the intended benefit and possible temporary effects.

Use a licensed medical professional who can assess your movement at rest and during expression. Tell them about prior botulinum toxin treatments, allergies, pregnancy or breastfeeding plans, neuromuscular disease, swallowing or breathing problems, and all medicines or supplements. Ask whether the aim is to soften a dynamic line or address another concern.

Read the treatment overview for [Botulinum Toxin Type A](/materials/botulinum-toxin-type-a/) and [Botox](/treatments/injectables/botulinum-toxin-injection/). If your concern is a hollow or contour change rather than muscle movement, [Dermal Fillers](/treatments/injectables/dermal-fillers/) involve a different approach.

Contact the clinic about increasing pain, swelling, redness, discharge, or unexpected difficulty moving nearby facial muscles. Seek emergency care for trouble breathing or swallowing, marked generalized weakness, severe dizziness, or sudden facial swelling. Do not wait for a routine review when these symptoms are intense or rapidly developing.

Ask: What muscle activity is causing my concern? What result is realistic for my facial movement? Which formulation will you use? What medical history could change the plan? When should I return for assessment?
