Nasolabial folds or smile lines are two skin folds that run on each side of the nose all the way to the corners of the mouth. They can be very superficial lines or deep folds.
They are caused by gradual facial volume loss that happens with ageing, when the facial fat pads, uniformly distributed in the face, during a younger age, start migrating downwards. As a consequence of this downwards migration the cheeks become heavier and their descent creates these nasolabial folds that become more and more prominent with the act of smiling or laughing.
A combination of aesthetic treatments such as Dermal fillers and collagen stimulating treatments such as Microneedling, Platelets Rich Plasma (PRP), Mesotherapy can be highly effective in softening the appearance of nasolabial folds.
