Chin Dimple and Cobblestone Chin: Mentalis Botox and Filler Guide 2026
Dr. Hamza Gemici
May 21, 202611 minutesQuick Summary · TL;DR
A pebbled or orange-peel chin and a deep line below the lower lip are not the same problem. The first is usually driven by mentalis overactivity, while the second may reflect a true structural mentolabial sulcus. Good treatment starts by deciding whether the issue is muscle, volume, or a combination of both.
Key Takeaways
- Cobblestone chin and deep mentolabial sulcus should not be treated as the same diagnosis.
- Mentails overactivity often responds better to Botox than to filler.
- Small, well-placed filler can help structural deficiency, but overfilling the chin crease looks unnatural quickly.
Patients often use the same words for two very different lower-face complaints: a dimpled, bunching chin and a deep line just below the lower lip. From a distance they may look related, but the treatment logic is different.
If the chin surface is being pulled and wrinkled by mentalis contraction, filler alone usually does not solve the problem. If there is a true sulcus or support deficit, toxin alone may not be enough either.
1. Understanding the two problems
Cobblestone chin is mainly a movement problem. Mentalis contraction bunches the skin upward and creates the orange-peel texture many patients notice when speaking or smiling.
A deep mentolabial sulcus is more of a contour or support issue. It may be worsened by the same muscle, but it is not the same as the dynamic skin bunching pattern.
- surface wrinkling points toward muscle overactivity
- a stable deep groove suggests structural deficiency
- many patients show a combined pattern and need staged treatment
2. When Botox leads and when filler leads
Mentalis Botox is the main treatment when the chin pebbles during expression and the soft-tissue bunching is the dominant complaint. Small, precise dosing matters because the area is central to lip competence and lower-face balance.
Filler becomes more useful when the lower-lip to chin transition is deeply tethered at rest or when support around the sulcus is genuinely deficient.
- Botox softens upward skin bunching from mentalis
- filler supports a true contour deficit
- combination treatment should still stay conservative
3. Risks and planning details
Too much toxin can change lip closure or create an elongated chin look. Too much filler can make the lower face puffy and obvious. Both errors come from treating the label instead of the anatomy.
For that reason I document movement, resting contour, and chin projection separately before deciding whether the patient needs toxin, filler, or both.
- small doses and clear review points are safer
- the central lower face punishes overcorrection quickly
- muscle activity and contour should be examined separately
Dr. Gemici: When a patient says "fill this chin crease," I first decide whether the real problem is the crease or the muscle that keeps creating it.
Frequently Asked Questions
Is a pebbled chin always treated with filler?
No. A pebbled or orange-peel chin is often primarily a mentalis overactivity problem and usually responds better to Botox.
Can Botox alone fix a deep line under the lower lip?
Not always. If there is a true structural sulcus, a small amount of support with filler may still be needed.
What is the biggest mistake in this area?
Treating all chin complaints as one diagnosis. The muscle and the contour issue have to be separated first.
