Frown Lines

Frown lines — the vertical creases between your eyebrows — form from repeated muscle movement and can give your face a tense look even at rest. At Desert Bloom in Scottsdale, Dr. Borakowski treats frown lines with neuromodulators and collagen-rebuilding approaches tailored to whether your lines are dynamic, static, or both.

What creates the 11s — and what fixes them

Dr. Borakowski assessing glabellar frown lines during a Scottsdale consultation

Frown lines (the vertical glabellar creases between the brows) form from years of corrugator and procerus pull. The first question at consultation is whether your 11s are still dynamic — creases that appear in motion and fade at rest — or have become static, etched into the skin even when fully relaxed. Dynamic lines respond to a neuromodulator alone. Static lines need a neuromodulator plus collagen-rebuilding work in the crease bed; a microdroplet of Restylane can soften a residual groove. Dr. Borakowski performs the frown test at every glabellar consultation and builds the plan around what she actually sees.

Treatments we offer

Frown line treatments at Desert Bloom

Three neuromodulators address muscle-driven 11s; RF microneedling and a microdroplet of Restylane address static residual creases. Dr. B selects the right combination at consultation.

Dynamic · first-line · 20 units

Botox

The most studied glabellar neuromodulator. Standard 20-unit dose across five injection sites, tight diffusion profile, 3–4 month duration. The conservative starting point for first-time patients.

See Botox details

Dynamic · wider pattern · ~50 units

Dysport

Abobotulinumtoxin-A diffuses more broadly from each injection site than Botox — useful when the frown pattern fans wider across the brow. Same 3–4 month duration.

See Dysport details

Dynamic · longer · ~6 months

Daxxify

PEG-peptide stabilizer extends glabellar duration to about 6 months (SAKURA phase-3 trials). Best for established responders who prefer two visits a year instead of three or four.

See Daxxify details

Static · collagen rebuild

RF Microneedling

Radiofrequency energy delivered into the dermis through fine insulated needles. Rebuilds collagen in the crease bed that toxin alone cannot reach. Added once 11s remain visible at rest between toxin appointments.

See RF Microneedling

Static groove · off-label

Restylane microdroplet

For a residual groove that stays visible after toxin at full effect. Microdroplet placement (~0.1 mL per side) adds volume to the static crease itself. Off-label, technique-sensitive, and only after a toxin plan is established.

See Restylane details

For most patients, frown-line treatment stays in the neuromodulator lane for years. RF microneedling and Restylane enter the plan only once a static residual crease has developed.

Start with what you see

Which path fits your 11s

Match your current pattern to the typical starting point. Dr. B confirms the route at consultation — and sometimes two paths combine into a single plan.

First time

This is my first time — I just want to soften the 11s.

→First-time route — First-line Botox at a conservative 20-unit dose. Dr. B reviews the result at the two-week mark before any adjustment, so dosing is dialed in before a longer-acting product is considered.

Wider pattern

My frown pattern fans wider than a clean pair of 11s.

→Wider-pattern route — Dysport's broader diffusion from each injection site covers a wider corrugator pull more evenly. Same 3–4 month duration, decision made at consultation based on your brow anatomy.

Longer duration

I want fewer visits per year.

→Longer-duration route — Daxxify's ~6-month duration usually means two appointments a year instead of three or four. Best suited to patients who already know their 11s respond well to neurotoxin.

Static crease

My 11s stay visible even when I'm fully relaxed.

→Static-crease route — The crease has gone static — muscle work alone isn't enough. RF microneedling rebuilds collagen in the crease bed; a microdroplet of Restylane can soften a residual groove if one remains after toxin settles.

Gradual onset and dose titration are the safety story

Neuromodulator results begin around days 3–5 and settle at the two-week mark. Dr. B starts conservative on first-time patients and adds a small top-up at the two-week follow-up if the corrugators are still pulling — adding units later is straightforward; reversing too much is not. Heavy upper eyelid ptosis or significant brow ptosis is screened at the physical assessment, because toxin can occasionally worsen ptosis if it diffuses into the levator palpebrae. All three neuromodulators carry no melanin-related risk and are appropriate for Fitzpatrick I–VI. Pregnancy, breastfeeding, active skin infection at the glabellar site, and neuromuscular disorders are absolute contraindications to toxin; isotretinoin within 6 months defers RF microneedling.

Frequently asked questions

At what age do frown lines usually start?

Most patients notice dynamic 11s between the late 20s and mid-30s — the crease appears in motion but fades completely at rest. Static frown lines that remain visible at rest typically develop in the mid-30s onward, earlier with significant sun exposure, fair skin, or particularly strong corrugator muscles. Starting preventative low-dose toxin in your late 20s or early 30s can meaningfully delay the transition from dynamic to static lines.

What is the difference between Botox, Dysport, and Daxxify for 11 lines?

All three are botulinum toxin type A products FDA-approved for glabellar lines. Botox has a tight diffusion profile and is the standard first-time choice. Dysport diffuses more broadly per injection site, useful when the frown pattern fans wider. Both last 3–4 months. Daxxify uses a PEG-peptide stabilizer that extends duration to roughly 6 months — two visits a year instead of three or four — and is best for established responders rather than first-time patients still dialing in dosing.

How many units of Botox do frown lines need?

The standard glabellar dose is approximately 20 units of Botox across five injection sites — two medial corrugator, two lateral corrugator, and one procerus point. The equivalent Dysport dose is about 50 units (aboBoNT-A conversion ≈ 2.5:1); Daxxify is typically about 40 units. Exact dosing varies with muscle strength; Dr. B starts conservative on first-time patients and adjusts at the two-week follow-up only if needed.

Can dermal fillers treat frown lines?

In a limited, specific way. When a static residual crease stays visible after botulinum toxin has taken full effect, a microdroplet of Restylane Refyne or RHA 2/3 (roughly 0.1 mL per side) can add volume to the groove itself. This is off-label use; the glabellar area sits near the ophthalmic artery, so technique and experience matter. It is never the starting procedure for a frown line — it follows an established toxin plan.

Does RF microneedling hurt on the forehead?

The glabellar area is moderately sensitive. We apply topical numbing for approximately 45 minutes before treatment. Most patients describe the sensation during the procedure as firm prickling with heat — uncomfortable but manageable. Mild redness and tenderness last 24–48 hours afterward, similar to a mild sunburn. Significant pain during the procedure is uncommon.

Will I still be able to show expressions after treatment?

A properly dosed neuromodulator softens the 11 lines without freezing your face. You should still be able to communicate surprise, concentration, and concern with normal expressions — the goal is a smoother glabella at rest and reduced crease formation in motion, not an immobile forehead. Dr. B doses conservatively and adds units only if needed at the two-week follow-up.

How long until I see results?

Onset begins around days 3–5; full effect lands at two weeks, which is why Dr. B schedules the follow-up exactly then. RF microneedling for static creases is a series — typically three sessions four to six weeks apart, with the final collagen remodelling continuing for about three months after the last session.
