Chin pebbling — also called cobblestone chin or "peau d\'orange" appearance — is a bumpy, dimpled chin texture that some patients show at rest or with movement. The cause is hyperactive mentalis muscle. Korean cosmetic medicine addresses this with conservative Botox treatment combined with other chin aesthetic refinements. This guide explains the comprehensive approach.
What chin pebbling is
- Bumpy, irregular chin texture.
- Resembles cobblestones or orange peel.
- Visible at rest in many patients.
- Worse with mentalis muscle contraction.
- Can affect chin\'s overall appearance.
Why it occurs
Mentalis muscle anatomy
- Paired chin muscles.
- Function: lift and protrude lower lip.
- Some patients hypertrophic from habit.
- Genetic factor in shape.
Hyperactivity causes
- Speech patterns.
- Repeated lip purse habits.
- Stress-related clenching.
- Sleep position effects.
- Genetic muscular activity patterns.
Aging contribution
- Skin elasticity loss.
- Reduced subcutaneous fat.
- Visible muscle activity through thin skin.
- Chin volume loss exposing structure.
Treatment options
Mentalis Botox (primary treatment)
- Relaxes overactive muscle.
- Conservative dose: 4–10 units total.
- 2 injection points typically.
- Lower chin area, midline.
- Effect onset 4–7 days.
- Lasts 3–4 months.
Filler augmentation
- Restores chin volume.
- Smooths surface contour.
- HA filler in chin area.
- Adjunct to Botox often.
- Hyaluronic acid filler.
Skin treatment
- Skin booster series.
- Improves texture.
- Addresses skin quality.
- Long-term improvement.
Combined approach
- Botox + filler + skin treatment.
- Most effective long-term result.
- Comprehensive chin aesthetic.
- Korean standard approach.
Korean technique
Conservative Botox dosing
- Lower doses preferred.
- Avoid speech impairment.
- Avoid lip incompetence.
- Subtle effect.
- Touch-up at 2 weeks.
Important precautions
- Avoid injection too high (affects lip).
- Stay below mental crease.
- Bilateral symmetric placement.
- Don\'t affect orbicularis oris.
Combined approach in single visit
- Mentalis Botox.
- Chin filler if needed.
- Skin booster considered.
- Comprehensive treatment efficient.
What chin pebbling looks like vs alternatives

Witch\'s chin (chin ptosis)
- Drooping chin.
- Volume below mental crease.
- Different treatment (chin lift, sometimes surgery).
Marionette lines
- Lines from mouth corners down.
- Different anatomy.
- Different treatment.

The honest framing
Chin pebbling is often overlooked but easily addressed with conservative Korean Botox technique combined with appropriate adjuncts (filler, skin boosters). The patients who get good outcomes have proper diagnosis, accept conservative dosing, and combine with other treatments for comprehensive lower-face refinement. Single-treatment approaches address only one component; combined approaches produce more natural and durable results. Korean clinics offer this as part of broader cosmetic medicine — appropriate addition to comprehensive aesthetic plans.
