Chin Botox (Mentalis) in Irvine, CA — Smooth a Dimpled “Pebble” Chin
Relax the chin muscle that creates dimpling and orange-peel texture.
Chin Botox in Irvine, CA
The mentalis is the chin muscle — a paired muscle that originates at the lower mandible and inserts into the overlying skin of the chin pad. Repeated contraction during speaking, chewing, and emotional expression creates a pebble-textured or dimpled appearance on the chin surface — a pattern that becomes more visible with age as the overlying skin thins and loses the elasticity that previously masked the underlying muscle activity.
Botulinum toxin injected into the mentalis reduces its resting tone and range of contraction, softening the chin texture at rest and during mild movement. The typical dose is 4 to 8 units placed centrally in the chin, avoiding placement too low on the mandible where it could affect the lower lip depressors. At Spectrum Skin Clinic, chin Botox is performed by Dr. Sabeen Munib and is often coordinated with other lower face treatments as part of a broader lower face plan.
What Causes a Pebble Chin
The pebble or orange-peel texture on the chin is caused by the mentalis muscle creating small indentations in the overlying skin as it contracts. The mentalis is active during pursing of the lips, closing the mouth firmly, and many emotional expressions. In younger skin, the overlying fat pad and skin elasticity smooth over this activity. With age — or in patients with a naturally active or hypertrophic mentalis — the muscle activity becomes visible at the surface as cobblestone-like dimpling.
Some patients with a pebble chin also have a chin that appears shorter or less projected than it actually is, because constant mentalis contraction elevates the soft tissue and partially obscures the bony chin definition. In these patients, relaxing the mentalis can both smooth the texture and slightly improve the apparent vertical length of the chin. This is a modest effect but is occasionally relevant in lower face planning.
Chin dimpling caused by volume loss or a shifted chin implant is a different problem from mentalis hyperactivity and is assessed separately. Botox addresses only the muscle activity component.
Chin Botox vs. Chin Filler
| Chin Botox (Mentalis) | Chin Filler | |
|---|---|---|
| What it does | Relaxes an overactive muscle | Adds volume / projection |
| Best for | Pebble or orange-peel texture, dimpling | A weak or recessed chin, balance/length |
| Result | Smoother chin surface | More defined chin shape |
Physician-Performed. Conservative by Design.
The mentalis sits close to the muscles that move the lower lip. Over-relaxing it can affect how you purse your lips or sip, so chin Botox calls for precise, conservative dosing. Dr. Sabeen Munib, MD places it to smooth the chin while preserving normal lip and chin movement.
What to Expect
Chin Botox at Spectrum Skin Clinic takes fifteen to twenty minutes. Dr. Munib places two to four injection points in the central chin, targeting the mentalis body. The injection uses a fine-gauge needle and causes minimal discomfort. No topical numbing is typically required for this area.
Minor redness or a small raised area at the injection site resolves within thirty to sixty minutes. Bruising is uncommon in the chin but possible given the density of surface vessels in some patients. Normal activities are resumed immediately — there is no downtime. Pressing on the chin or lying face-down for two to four hours after treatment is avoided.
The smoothing effect develops over seven to fourteen days as the mentalis relaxes. Most patients notice the change in chin texture around day ten. Results typically last three to four months before a maintenance session is considered.
Who May Benefit
Chin Botox is most effective for patients whose primary concern is mentalis hyperactivity — visible dimpling or pebble texture driven by muscle contraction rather than volume or skin changes. The assessment at consultation distinguishes between these causes.
Patients who may also benefit from chin filler are those with reduced chin projection or volume loss at the chin pad. The two treatments address different problems but are frequently combined — Botox smooths the muscle activity while filler restores projection or softens the chin contour. Whether a combined approach is appropriate is confirmed at consultation.
Pairs Well With
Chin Botox is often combined with chin filler for shape, or with a lip-area plan for lower-face balance.
Chin Filler — for projection, length, and lower-face balance.
DAO Botox — for downturned mouth corners.
Gummy Smile Botox — for upper-lip elevation and gum show.
