Crow's feet

Crow’s feet are the lateral canthal lines that become more visible with smiling and repeated orbicularis oculi activity. They are a common aesthetic indication for botulinum toxin type A in facial treatment discussions.

Why botulinum toxin is relevant

This indication demonstrates how botulinum toxin can be used to soften dynamic facial lines created by muscle contraction. It extends the encyclopedia’s indication cluster beyond therapeutic neurology and into high-visibility aesthetic care.

Typical use context

Crow’s feet are often treated as part of cosmetic facial planning around the upper face, sometimes alongside glabellar or forehead concerns. As with other aesthetic uses, how a product is labeled or commonly used can vary by region and clinical setting.

Common brands or toxin types used

Dosage and injection considerations

Treatment planning usually centers on the lateral orbicularis oculi pattern, facial animation, and the balance between wrinkle reduction and a natural smile. Product units are brand-specific and should be interpreted in the context of the individual formulation. The dilution and reconstitution page gives a practical overview of how injection volume and local anatomy affect that reading. The dose calculation overview page adds the per-site logic that sits behind those small-area treatment discussions.

Safety and limitation notes

Because this is a highly visible facial area, subtle asymmetry or an overtreated look can become a patient concern if treatment is not tailored carefully. Results are temporary, and expectations should account for variation in anatomy and expression habits. The injection anatomy overview page helps place that periocular pattern alongside therapeutic facial and non-facial treatment contexts. The safety and adverse-effect framing page helps readers interpret visible weakness or spread concerns without flattening them into a single brand claim.
