Glabellar lines may come from repeated corrugator and procerus activity, a crease already present at rest, or both. Treatment should begin by assessing facial movement, brow position, upper-eyelid heaviness and skin quality. Reducing muscle activity can soften a dynamic line, but it cannot guarantee complete removal of a static crease.

Dynamic lines and static creases need different reasoning

Why brow position matters before Botox

The corrugators draw the brows inward and slightly downward. The procerus contributes to downward movement over the nasal bridge. The frontalis elevates the brow and may compensate for brow descent or upper-eyelid heaviness. Treating the glabella without examining this balance can make the brow feel heavier even when the injection itself is correctly placed.

Patients should report previous heavy brows, eyelid ptosis, asymmetric movement and the timing of their last neuromodulator treatment. Standardized photographs at rest, frown and brow elevation clarify which muscles are contributing.

Neuromodulators are effective, but adverse effects are real

A multicenter randomized placebo-controlled trial involving 264 patients found that botulinum toxin reduced glabellar-line severity through the study period, while mild blepharoptosis occurred in a small proportion of treated patients. Later systematic evidence also identified headache, eyelid ptosis and heavy eyelids among relevant adverse effects.

Dose, placement and balance with the frontalis should therefore reflect anatomy and prior response. A motionless forehead is not the objective. Preserving recognizable expression may mean accepting some movement and some residual line.

Why glabellar filler requires exceptional caution

The glabella is connected to vessels that communicate with the ophthalmic circulation. Filler-related arterial occlusion can cause skin necrosis, ophthalmoplegia, eyelid ptosis and irreversible visual loss. A clinical series of periorbital vascular complications included several glabellar injections and found poor visual outcomes when the central retinal or ophthalmic artery was affected.

For this reason, filler should not be presented as a routine solution for a static glabellar crease. A published case of ophthalmic-artery occlusion after glabellar hyaluronic-acid filler resulted in persistent blindness despite urgent treatment. Rare does not mean negligible when the consequence is severe.

Skin treatment has a separate role

Medical skincare, fractional laser, selected microneedling or other dermatologic procedures may improve texture and a superficial static line. Choice depends on skin type, pigment risk, scar history, previous energy treatment and acceptable downtime. These treatments do not reposition the brow or eliminate muscle contraction.

When video-assisted brow surgery enters the discussion

Video-assisted surgery treats selected brow descent and upper-face anatomy; it is not a permanent wrinkle injection. Dr. June’s approach assesses forehead length, hairline, brow shape, asymmetry, frontalis compensation and the desired degree of repositioning. Through four or five scalp portals, the orbital retaining ligament and related attachments can be released, and fixation is planned in an individualized vertical vector.

The operation may be combined with Hybrid Blepharoplasty when both brow and eyelid anatomy contribute. Risks include scalp scars, hair changes, altered sensation, asymmetry, fixation problems and temporary or persistent nerve weakness.

Previous filler and ultrasound

If the glabella or surrounding forehead has been injected, the product, date and complications should be documented. Dermatologic ultrasound may help identify hyaluronic acid, fluid or tissue change when the history is uncertain. Hyaluronidase acts on hyaluronic acid; it does not remove PMMA, silicone, biostimulators or fat.

Planning treatment from abroad

A remote consultation can review photographs and treatment history, but surgery requires in-person examination. Major upper-face procedures are performed at Hospital São José. The Belvivere Concierge assists international patients with accommodation and transportation while medical follow-up remains with the clinical team.
