Dimple is the indentation that occurs in the cheek skin which often appears only when you smile. Dimples are formed due to an anatomical variation or deficiency in the facial muscle Zygomaticus major. The split in the muscle creates depression when we smile.
Dimple naturally occurs in babies due to the presence of the baby fat, but gradually disappears in many as they grow. They happen in both genders with no specific prevalence. Around 20-30% of the world’s population and also its prevalence varies in different parts of the world. Dimples are viewed as an appealing element as they emphasize a woman’s grin and enhance facial appearance. In many cultures, dimples are a sign of beauty, youth, and luck.
