Chin Dimpling Botox: Smooth a Cobblestone Chin
Chin dimpling, sometimes called “cobblestone chin” or “orange peel chin,” is caused by an overactive mentalis muscle. A small amount of Botox creates one of the most dramatic per-unit improvements in cosmetic treatment.
Chin Dimpling: Caused by Muscle, Corrected with Botox
The pebbled, dimpled texture that appears on the chin — during expression or even at rest in more pronounced cases — is caused by the mentalis muscle. This muscle controls chin movement during speaking, swallowing, and emotional expression. When it is overactive or hyperkinetic, it creates an uneven, textured surface on the overlying skin that many patients find cosmetically bothersome.
Botox injected into the mentalis muscle reduces its activity and smooths the chin surface significantly. Treatment typically requires 4-8 units, results appear within a week, and the improvement is consistently one of the most dramatic-per-unit outcomes in cosmetic Botox. It is frequently combined with lip line treatment and neck bands as part of a lower face plan.
The mentalis, orbicularis oris (lip lines), and platysma (neck bands) all function as part of the lower face muscle complex. Patients who address chin dimpling often find that treating the surrounding areas at the same visit produces a more cohesive result. Our clinicians assess the lower face as a unit at consultation and can recommend which combination makes clinical sense for your specific presentation.
All Botox treatments at Tactus Health are performed by our licensed medical team under the clinical oversight of Dr. Ashar N., DNP, APRN, FNP-C, Medical Director. Every treatment includes a two-week follow-up assessment.
Frequently Asked Questions
A pebbled, orange-peel, or cobblestone texture on the chin surface. In milder cases it only appears during expression. In more pronounced cases it is visible at rest. It is caused by the mentalis muscle creating uneven surface tension in the overlying skin. Most patients notice it has been present for years before seeking treatment.
No. The mentalis muscle remains fully functional. Botox reduces excessive activity, not normal function. Speech, chewing, and emotional expression are unaffected at appropriate dosing. The goal is to reduce hyperkinetic activity while preserving the muscle’s normal role.
Most patients see significant smoothing within 5-7 days of treatment. Full results are visible by day 10-14, which is why the two-week follow-up is included with all Botox treatments at Tactus Health. If any adjustment is needed, it is addressed at that appointment.
The mentalis is a relatively small, isolated muscle with a direct and visible effect on chin surface texture. When it relaxes, the skin above it smooths quickly and completely. There are no competing muscle groups that partially undo the effect, as there are in the forehead. For 4-8 units of Botox, the visible change is often more striking than a full forehead treatment at 15-20 units.
Yes. Botox addresses chin texture while dermal filler can add projection and definition to the chin shape itself. The two are complementary and frequently performed together. Botox is typically done first, and filler is placed once the muscle is relaxed to allow more precise placement. Your provider will discuss whether filler makes sense for your goals at your consultation.
