There are many, many, short-term and long-term consequences of sleep deprivation. The most clinically apparent ones – swollen, sunken eyes; dark circles; and pale, dehydrated skin – are obvious. However the subclinical consequences are not so obvious. Sleep deprivation affects wound healing, collagen growth, skin hydration, and skin texture. Inflammation is also higher in sleep-deprived patients, causing outbreaks of acne, eczema, psoriasis, and skin allergies.
The reduction of sleep time affects the composition and integrity of the skin. Sleep deprivation increases glucocorticoid production. The elevation of cortisol inhibits fibroblast function and increases matrix metalloproteinases (collagenase, gelatinase). Matrix metalloproteinases accelerate collagen and elastin breakdown, which is essential to skin integrity, and hastens the aging process by increasing wrinkles, decreasing skin thickness, inhibiting growth factors, and decreasing skin elasticity.
Are there treatments to reverse these signs? Yes. Treatments to help increase skin collagen production include microneedling, radiofrequency devices, fractionated lasers, and topical agents such as retinoids. However, we cannot readily reverse the impact inflammatory processes, skin barrier dysfunction, or the disruption of the skin biome has on our skin. Beauty sleep is both necessary and irreplaceable.
