Sleep is of the upmost importance for skin health. Sleep allows the body to renew and rejuvenate itself afresh for the morning. If the body is lacking in ample amounts of sleep each night, it doesn’t have enough time to rejuvenate overnight and therefore, parts of the body, especially skin cells, can remain damaged from previous days. Damaged skin cells appear dry, tired, wrinkled and grey. Skin luminosity and health is lost. One of the best ways to revive skin is through sleep.
