Most people know botulinum toxin works well for crow’s feet. But can botulinum toxin for under-eye wrinkles deliver the same results? The short answer is yes, but only for specific types, and it requires highly precise technique due to the delicate anatomy of the lower eyelid.
Can Botulinum Toxin Treat Under-Eye Wrinkles?
Botulinum toxin primarily targets dynamic wrinkles——those that appear during facial expressions such as smiling or squinting. For the lower eyelid, these are caused by contraction of the orbicularis oculi muscle.
Clinical studies confirm that botulinum toxin can improve infraorbital wrinkles. A dose-finding study found that both patients and physicians reported visible improvement in lower eyelid wrinkles after injection, with doses as low as 2–4 units per side being effective.
Clinical Evidence
Efficacy: A prospective clinical trial using intradermal microneedle injection (2–3 units per side, 4–8 points) demonstrated significant improvement in lower eyelid dynamic wrinkles at 3-month follow-up.
Dosing caution: Higher doses (e.g., 8 units per side) produce a dose-response effect but significantly increase side effects, including bothersome lower eyelid edema and incomplete sphincter function. The authors recommend using low doses (2–4 units) for this area.
Important Limitations
What botulinum toxin cannot address:
- Static wrinkles (visible at rest, caused by collagen loss and skin thinning)
- Tear trough hollows (volume loss)
- Dark circles
- Under-eye bags (fat protrusion or fluid retention)
These conditions require alternative treatments such as dermal fillers, laser resurfacing, or surgery.
Safety Considerations: Why Technique Matters
The lower eyelid is a high-risk area. Uncontrolled diffusion or incorrect dosing can lead to:
- Lower eyelid edema and swelling
- Eyelid laxity or “false dermatochalasis” (skin sagging from fat prolapse)
- Diplopia (double vision) in more serious cases
The lower eyelid skin is only 0.2 mm thick, and the underlying orbicularis oculi muscle lies approximately 2.0 mm beneath the skin surface, making precise placement essential.
Who Is a Good Candidate?
You may benefit if:
- Your under-eye wrinkles appear mainly when smiling or squinting
- Wrinkles are fine and expression-related
Who Should Avoid Treatment?
Botulinum toxin may not be the best option for everyone. Treatment may not be suitable if you:
- Have under-eye bags, tear trough hollows, or dark circles as your primary concern
- Have static wrinkles caused mainly by skin aging rather than muscle movement
- Have significant lower eyelid laxity or persistent under-eye swelling
FAQ
Can botulinum toxin remove under-eye wrinkles completely?
No. Botulinum toxin is most effective for dynamic under-eye wrinkles and cannot correct static wrinkles, tear troughs, or under-eye bags.
How many units of botulinum toxin are used under the eyes?
The dose varies by patient, but low doses are generally recommended because the lower eyelid is a delicate treatment area.
How long do the results last?
Results typically become visible within 3–7 days, peak at around 2 weeks, and generally last 3–4 months.
Can botulinum toxin make under-eye bags worse?
Yes, in some cases. Relaxing the lower eyelid muscles may make existing under-eye bags or eyelid laxity appear more noticeable.
Is botulinum toxin safe for under-eye wrinkles?
Yes, when performed by an experienced injector using conservative dosing and precise technique in appropriately selected patients.
Conclusion
Does botulinum toxin work for under-eye wrinkles?
Dynamic fine lines beneath the eyes – Yes, in selected cases
Static wrinkles, hollows, bags, dark circles – No, these require different treatments
Botulinum toxin can improve dynamic lower eyelid wrinkles, but this is an off-label use that demands conservative dosing and expert injection technique. The risk of complications increases significantly with higher doses, making practitioner experience and precise placement non-negotiable.
