Crow’s feet are made by the orbicularis oculi, the ring of muscle that closes the eye. Because that ring also does the genuine part of a smile, the goal here is never to stop it moving.
Why the goal is not to erase them
A real smile involves the eye. The orbicularis contracting at the outer corner is what separates a genuine smile from a polite one, and photographs read the difference immediately even when nobody can name it.
So the target here is the outer fibres only, at a dose that softens the depth of the lines without flattening the expression. An eye area with no movement at all in a smiling photograph is the signature of over-treatment, and it is more noticeable to other people than the lines were.
Dose and injection points
8 to 16 units per side, split across roughly three points at the outer orbital rim, staying at least one centimetre outside the bony margin.
Two things move the number: how much of the line is produced by squinting rather than smiling, and skin quality. Fine crepey lines under the outer eye often come from sun damage and skin thickness rather than muscle, and adding units does not touch them.
Injections stay lateral. Product placed too close to the lower lid can weaken the lid support and produce a temporary change in the eye's shape or, rarely, watering. Like the glabella, this is a technique matter rather than a product one.
What crow's feet botox costs
| Crow's feet | Price | Approx. USD |
|---|---|---|
| Crow's feet (both sides) | $350,000 COP | USD 110 |
| Crow's feet + one more zone | $650,000 COP | USD 200 |
| Full upper third | $850,000 COP | USD 265 |
Both sides count as a single zone. The unit count varies with muscle strength and is given to you before anything is applied.
Consultation is free and the 15-day review is included. The full rate for every area is on the price page.
What this area will not fix
- Crepey skin under the eye. That is dermal thinning and sun damage. Toxin does nothing for it, and relaxing the muscle underneath can occasionally make loose skin look slightly worse rather than better.
- Under-eye hollows or dark circles. A volume and pigment question, not a muscle one.
- Lines from a lifetime of squinting in bright light. Partly, at best. If you live somewhere sunny and do not wear sunglasses, the single most effective intervention is sunglasses.
If the concern is skin quality and laxity around the eye rather than the lines themselves, Ultraformer MPT is the tool that addresses that layer, and it is a different treatment with a different price.
