According to the classical face-reading texts, Laughter Lines, which extend from the nose, down the sides of the mouth to the chin, should not become noticeable until the age of 45. If someone has pronounced or obvious Laughter Lines prior to this age, it is an indication of a hard life or a person whose nose is always to the grindstone. However, after 45 the presence of Laughter Lines is not only desirable but a requisite for longevity. Indeed, as a person advances past the age of 45, the presence of Laughter Lines is not only desirables but a requisite for longevity.
Indeed, as a person advances past the age of 45, the Laughter Lines should ideally deepen, lengthen and broaden. Laughter Lines that are faint, tight to the corners of the mouth or short are definitely not what you want to see as you age.
So it’s a great idea to lighten up on the Botox after the age of 45 and smile more often because with a good Laughter Lines you will be laughing for a long time.
