Yes, there are two types of dimples: temporary and permanent.
Dimples are those charming little indentations in the skin, often found on the cheeks, but they can appear in other locations as well. The classification of dimples into temporary and permanent categories primarily refers to their visibility and cause.
-
Permanent Dimples: These are typically caused by a genetic variation affecting the facial muscles, specifically the zygomaticus major muscle. In individuals with dimples, this muscle may be bifid (split), creating a tethering effect on the overlying skin when smiling or making certain facial expressions. This tethering is what causes the visible indentation or dimple. Because the muscle structure is permanent, the dimples are usually present throughout life, although they may become less noticeable with age due to changes in skin elasticity and fat distribution.
-
Temporary Dimples: These dimples are not due to underlying muscle structure variations but can be caused by temporary factors like facial expressions or slight indentations that appear only under specific lighting conditions. They might also be caused by temporary swelling or minor injuries. These dimples disappear when the triggering cause is removed.
In summary, permanent dimples are a result of muscle structure, while temporary dimples result from temporary conditions and are not a fixed feature. While cheek dimples are the most recognized, dimples can also occur on other body parts.
