You may have heard it: If you habitually sleep on your left, you may get more wrinkles on your left.

Before you fret over your sleep position, read on. According to a study conducted by Michigan-based plastic surgeon, Dr. Brett Kotlus, seem to suggest something different.

sleeping on side cause wrinkles

The research, titled “The Effect of Sleep Position on Perceived Facial Aging,” polls 100 women on their preferred sleep position and then an independent expert observer looks at their frontal images to identify the side with more wrinkles.

The result?

They found no correlation between the side you sleep on and the appearance of wrinkles.

However, prior to the study by Dr. Brett, New York dermatologist Dr. Debra Jaliman, had advised that the way you sleep does affect where your wrinkles form. Dr. Jaliman said, “If you crunch your face against a pillow you can get them.”

Dr. Jaliman advises using satin instead of cotton pillowcases because your face slides against satin and doesn’t crunch against it.

Actually, a few aesthetics doctors that Daily Vanity has spoken to on a casual basis have also mentioned that the side that you sleep on can cause “sleep lines”, which are lines that formed because of long period of exerting pressure on one side of your face, typically because of the way you sleep. As such, the doctors that we’ve chatted with suggested that you should sleep on your back instead, to ensure that pressure is distributed evenly and your facial contours can remain symmetrical (a yardstick of beauty).

Do you sleep on your side? Do you observe more lines on the side you sleep on?
