We have observed that there is redness on the face due to shyness and the color of the cheeks becomes pink. On the other hand, we see that dimples are formed on the faces of many men, women, and children while speaking and laughing.
Science behind dimple
Dimples are considered a sign of beauty. But in reality, this is a kind of flaw. The facial muscles, when for some reason remain small, the face has to be pulled slightly while laughing, and in this case, dimples appear in the cheeks, to make up for that shortfall.
When the baby is in the mother’s womb, for some reason, some changes take place in the subcutaneous connective tissue. This change is the reason for the dimple.
In some people, dimples appear on their cheeks as they age, but their facial muscles are not visible in puberty. This doesn’t happen with some and their cheeks get dimples even after they grow up.
Why the face turns red during shyness?
Actually, shyness is an emotion. It is related to shyness. Adrenaline starts secreting from our adrenal gland as soon as we feel inhibition.
This activates an enzyme called adrenaline cyclase. As a result of which the level of cyclic adenosine monophosphate (cyclic AMP) increases.
Due to increased levels of cyclic adenosine monophosphate, blood vessels dilate and our face turns pink or red in color.
Compared to other parts of the body, our cheeks have more blood vessels and more nearer to the surface, so their effect is clearly visible to us.
