In 1999, Fulton et al had proposed that sleep positions and the site of superficial musculoaponeurotic system (SMAS) condensation may be responsible for sleep wrinkles development. In his paper, Fulton had also described the commonest areas where sleep wrinkles could develop. Even before Fulton, in 1987, Dr. Stegman had published a paper on ‘sleep creases’, and postulated that sleep creases were less noticeable after a few nights of sleep in which the subject’s face was not pushed against the pillow.
