What is it?
Smile lines, also known as nasolabial folds or laugh lines, are creases that extend from the sides of the nose to the corners of the mouth. These wrinkles can become more prominent and permanent with age, particularly if the skin is not adequately protected from factors such as sun exposure or smoking. Smile lines primarily develop around the mouth but can also occur around the eyes.
As facial features, they are a natural part of aging but can be minimized with various cosmetic treatments or skincare regimens.
