Smile lines, with their many names—nasolabial folds, laugh lines, parentheses lines—are those, often deep, wrinkles that run from the sides of your nose down to the corners of your mouth. These lines appear naturally when you smile or laugh, and can even be seen on smiling children, but with age they become a permanent, visible facial feature regardless of expression.
Straight-faced smile lines are the result of the loss of skin elasticity and facial volume, and are often one of the first indications of premature aging; they can appear as early as the mid-20’s, or sometimes earlier. Another contributing factor of smile lines is the loss of fat in the upper part of the cheek area. As we age, the fat’s attachment to the underlying cheekbone loosens and weakens, and as a result, the fat drops, causing the smile lines to appear more prominent.
While smiling often may make these lines appear faster, not smiling is not an effective way to prevent them. So smile often, and take advantage of the many treatments available that can help make these lines disappear.
