Why do we call it beauty sleep? It is because you should wake up looking rejuvenated and transformed from a tired complexion. Sleep is a form of self-care, so opt for bedding that nurtures your hair and skin while you sleep. Many individuals insist on sleeping exclusively on silk to maintain their hair and skin, but do these luxurious fabrics have an impact? Dermatologist Dr. Radmila Lukian says that when we sleep, “skin cells regenerate” and “essential proteins” for our skin’s appearance increase. Also, while we sleep, the skin’s “protective barrier strengthens, helping it retain moisture and shield against environmental stressors.” "The fabric of your pillowcase can have a notable effect on your skin. Coarse or abrasive fabrics can lead to friction, potentially causing skin irritation and even tiny tears," explained dermatologist Dr. Radmila Lukian. Cotton pillowcases can often lead to frizziness or tangled hair due to increased friction and can also potentially dry out your skin. Bacteria and general dirt can build up on your pillowcase, which can cause your hair to look dull and lank. Silk pillowcases are considered the best option for your hair and skin’s health, as they reduce friction and help prevent wrinkles. Satin is a cheaper alternative, as it also has a smooth surface to accommodate your hair and skin’s needs.
