How does sleep posture affect facial skin?
Sleeping on the back is an ideal position for sleeping!
First, you are not applying much pressure on your facial skin; this will cause fewer fine lines, less flattening of the facial contours and will make your skin younger and smoother. Also, your face won’t touch the pillowcase, avoiding the back-and-forth exchange of oils, dirt, and grime. This will prevent skin irritation or zits!
If you are a lover of sleeping on the side
This position causes less damage to the skin than the stomach position. However, this isn’t the ideal position either.
When you sleep on your side, you put tremendous pressure on one side. It flattens the cheekbone and triggers wrinkles on the side because of all the friction and pressure. Also, if you have applied any skincare product, the product might spread on the pillow and not get absorbed by your skin.
