What is this little indent in my chin? (photo)

The indent you’re describing in your chin, which becomes more prominent when smiling, is likely a type of dimple. Dimples, including those on the chin, are generally caused by variations in the underlying bone structure or the way muscles and skin are positioned. Chin dimples, sometimes referred to as "cleft chins," are typically genetic and quite common.

If you are considering dermal fillers to reduce the appearance of this indent, they can be an effective option for adding volume and smoothing out the area. Fillers are minimally invasive and can provide temporary results, usually lasting several months to a year, depending on the type of filler used.

Before proceeding, it’s important to consult with a qualified dermatologist or cosmetic surgeon. They can assess your specific situation, discuss the potential outcomes, and ensure that fillers are the right choice for you. They can also advise on any other treatment options that might be suitable.

Thank you for your question, and I hope this information is helpful as you consider your options.
