Smile & laughter lines

WHAT ARE SMILE LINES?

Smile lines, nasolabial lines, or marionette lines, are wrinkles on the face that start at the nose and run all the way down to the corners of the mouth.Smile lines are different from wrinkles that appear on other parts of the face, and they often appear as a single, deep crease, rather than many shallow lines.

How are smile lines formed

Smile lines form the same way any other lines or wrinkles on the face are formed. They appear as a result of collagen being depleted from the skin due to constant creasing of a particular area. Collagen also reduces as a natural part of the ageing process, alongside elastin, which is a protein that would usually provide support.Facial movements and expressions are controlled by firm facial muscles, and it is widely believed that smiling activates at least two dozen of them.

While your body is producing less collagen, robust and repetitive movement of the muscles creases the epidermis above them. The age at which most people start to get laughter lines can vary from your late twenties to your early thirties.Face CreasesConstant creasing at the same spot breaks down the skin and weakens the elastic bond that gives it its volume. The loss of that elasticity allows the skin to drop and weaken, which forms a line on the face. Depending on how much collagen was lost, the lines can range from shallow and subtle, very deep and prominent.
