The Role of Subcutaneous Tissue
Muscles are not the only determining factor. The thickness of the fat layer under the skin also decisively influences the visibility of the dimple. When the adipose tissue is thinner, the indentation is more pronounced. Conversely, in faces with fuller cheeks, the dimple may be less prominent or even disappear completely. This explains why some people notice their dimples becoming more or less evident depending on weight fluctuations throughout their lives.
A genetic inheritance that follows its own rules.
If you have dimples, it’s very likely you inherited them from one of your parents. Geneticists explain that this trait is transmitted under a pattern called autosomal dominant. In simple terms, this means that if just one parent carries this characteristic, there’s a high probability it will appear in their children.
However, human genetics doesn’t always behave like a perfect manual. There are cases of people who develop dimples without any obvious family history, as well as the opposite situation where they fade over the years. The natural loss of skin elasticity during aging can modify the appearance of these marks, making them less noticeable or changing their shape.
