What causes chin creases, clefts or dimpling?
Chin dimpling, also known as “pebble chin” or “golf ball chin,” occurs due to various factors that affect the underlying muscles and skin. The most common causes include:
1. Overactive Mentalis Muscle – The mentalis muscle, located in the chin, is responsible for controlling lip and chin movement. When this muscle contracts excessively, it can create a dimpling effect on the skin. This often becomes more pronounced with age as collagen and elastin levels decrease, making the skin less smooth.
2. Loss of Skin Elasticity – As we age, our skin loses collagen, leading to a reduction in firmness. This can make dimples or creases in the chin more noticeable, especially when talking, eating, or making facial expressions.
3. Acne Scarring – Past acne breakouts can leave behind scar tissue, creating indentations or uneven texture on the chin. These scars contribute to the appearance of dimpling, especially when combined with natural muscle contractions.
4. Genetics – Some individuals are genetically predisposed to having a more textured or dimpled chin due to inherited facial muscle structure and skin composition.
5. Habitual Movements & Expressions – Frequent pursing of the lips, frowning, or other repetitive facial expressions can overwork the mentalis muscle, leading to deepening dimples or creases over time.
Addressing Chin Dimpling
Fortunately, treatments such as wrinkle relaxers can help smooth the appearance of chin dimpling by relaxing the overactive mentalis muscle.
