Another major factor contributing to the phenomena of ageing is the loss of elasticity in the skin due to collagen reduction. To restore elasticity in the skin remains one of the leading research elements in the science of Anti ageing.
When we lie down to sleep, a major area of the face comes in contact with an antagonising surface causing a compression force against it. This compression persists till the time the posture is changed during sleep. This force causes an unusual positioning of the facial musculature and overlying skin. The repetitive, consistent and persisting positioning during sleep causes the creases referred normally as sleep wrinkles. Studies show that sleep wrinkles are caused mostly in the cases of sleeping on stomach or sideways. If you experience asymmetrical and obvious stubborn lines on the face not responding to anti wrinkle injections then these could be sleep wrinkles. They mainly appear on the forehead, cheeks or the angles of mouth. As these lines are not caused by the physiological contraction and relaxation of facial muscles so they do not respond to anti wrinkle injections. The same reason causes them to be at angles different from the regular expression lines.
A good example can be the compression marks around the waist area after wearing a tight trousers/dress. After a few hours of removing the dress, the compression marks are gone due to the elastic nature of the skin and ample fat padding in that area. Imagine if you wear the same dress everyday for 7-8 hours for numerous years with the gradual loss of skin elasticity and loss of structural fat as it happens in the face, the marks carry a huge tendency to become permanent. Now to avoid the sleep wrinkles, the easiest advise can be to change the sleep posture, just like not wearing that dress again. However, it can be an impractical advice as we may choose to begin our sleep in a posture free of any compression against the face, but as we dwell into the deeper aspects of sleep, the posture does not remain our choice.
A few everyday recommendations to avoid sleep wrinkles can be to go to bed well hydrated, use appropriate cosmeceuticals to provide skin its moisture during sleep and maybe try special anti wrinkle pillows designed to minimise facial contact with the pillow surface.
Hyaluronic Acid (HA) based Dermal Fillers have a role in treating Sleep wrinkles. They not only fill up the sleep wrinkles mechanically, but the physiological stimulation of collagen synthesis by HA contributes to the thickening of the skin over time and improving the elasticity. However, It would need multiple treatments and the results may vary depending on the extent and depth of sleep wrinkles. It is of importance to be mindful that the dynamic factor of sleep position would remain the major contributory factor in the mechanism of sleep wrinkle formation. So the mainstay of the treatment of sleep wrinkles through HA Dermal Fillers would be to achieve softening of the wrinkles giving out beautiful aesthetically pleasing results.
