Dimples are considered as one of the most attractive and charming spots on your face which can make your smile sweeter. The reason why dimples are not appeared on everyone’s face is because it’s genetic. That is, if your parents have dimples, you have a chance to have ones up to 50%. Normally, there are 2 types of dimples consisting of chin and cheek dimples. Some have both cheeks but some have just only one.
Anatomically, dimples are caused by the facial muscle called zygomaticus major. Dimples are caused when your facial muscle – zygomaticus major, is shorter than normal which pulls on your skin and forms the indentation in your facial skin. Cheek dimples are formed by the double or bifid zygomaticus major muscle.

In some societies, people who have dimples are considered as charming. Therefore, those who don’t have ones from genetic usually make a decision to go under the knife because nowadays dimple operation takes only local anesthesia and 30 minutes.
However, if you don’t take care of your wound and inside your mouth after an operation well, infection can be occurred. Importantly, before deciding to do an operation, you should study more information and choose only specialized board certified surgeon. Or else, the result will be disappointing, unnatural and can be resulted in problems in the future.

MAKE AN APPOINTMENT
It is minor surgery to create a dimple on the cheek or chin. It is done from inside the mouth under local anaesthesia and takes about 30 minutes.
The incision is inside the mouth, so there is no visible external scar. You need to keep your mouth clean as advised by the doctor to prevent infection.
Natural dimples come from a shorter or split zygomaticus major muscle that pulls the skin into a dimple when you smile, and they are often inherited.
Choose a board-certified plastic surgeon for natural-looking dimples and lower risk after surgery.
