Crow's Feet Botox in Irvine, CA — Softer Lines Around the Eyes

Crow's feet are produced by the lateral fibres of the orbicularis oculi — the sphincter-shaped muscle that closes the eye. On smiling and squinting these outer fibres fold the thin periorbital skin into fan-shaped lines radiating from the eye's corner. Crow's feet Botox targets these lateral fibres only.

What it deliberately AVOIDS: the medial orbicularis at the lower lid (lid closure, tear distribution), the zygomaticus major below (genuine smile), and the levator labii superioris medially (upper-lip elevation). Drift into any of these can produce a lazy lower lid, asymmetric smile, or lip ptosis. Dr. Sabeen Munib, MD places injections ≥1 cm lateral to the lateral canthus and superficial.

Bruising is slightly more common here than the forehead because periorbital skin is thin and crossed by fine vessels. Dr. Munib uses fine-gauge needles, slow injection, and asks patients to stop fish oil, vitamin E, NSAIDs, and alcohol 48 hours before treatment when not medically required.

The eye-bag appearance some patients describe after crow's feet Botox is uncommon and is usually not Botox spreading — it typically reflects lateral orbicularis relaxation allowing pre-existing lower-lid laxity or fat pads to read more prominently. True eyelid ptosis from a crow's feet injection is rare when units stay superficial and ≥1 cm lateral to the lateral canthus, because the levator palpebrae sits well medial and deep to that field. Dr. Sabeen Munib, MD mitigates these risks with low first-treatment units, lateral placement, and conservative depth. Reviewed by Dr. Sabeen Munib, MD on May 26, 2026.

When crow's feet Botox is the wrong procedure: significant lower-lid laxity, prominent pre-existing eye bags, or a thin lateral lid envelope. Dr. Munib will say so and suggest periorbital RF, fractional resurfacing, or under-eye filler / PRFM instead — not more Botox.

Crow's feet, forehead (frontalis), and glabella (corrugator + procerus) act as a balanced upper-face system. Relaxing one without considering the other two can shift expression — a frozen forehead next to active crow's feet, or a heavy brow if the lifters work without their depressors. Dr. Sabeen Munib, MD evaluates all three at consultation.

When the lateral orbicularis is relaxed, the brow tail may sit slightly higher — a subtle Botox brow lift. Combining crow's feet with a small dose of forehead or glabella Botox lets Dr. Munib shape upper-face position deliberately.

Crow's feet Botox uses onabotulinumtoxinA; the same area can be treated with abobotulinumtoxinA (Dysport) or incobotulinumtoxinA (Xeomin). Dysport tends to spread slightly more — useful across a broader smile-line area, but it raises the bar for precise lateral placement near the eye. Xeomin lacks the accessory protein and may suit patients concerned about long-term antibody response.

Unit conversion is not 1:1 (Dysport runs roughly 2.5–3 units to 1 unit of Botox), so quoting 'units' across brands without naming the brand is misinformation. Dr. Sabeen Munib, MD selects based on prior response, smile-pattern width, and patient history.
