What effect does sleep have on the skin?

Getting extra sleep benefits the skin. During sleep, the skin's metabolic rate increases, helping dry skin become more hydrated and restoring dull skin to a healthy glow, thereby achieving a beautifying effect.

Sleep can enhance skin elasticity, reduce fine wrinkles, regulate overactive sebaceous glands, and lower the likelihood of acne and breakouts. It is recommended to apply a moisturizer containing human-like collagen or hyaluronic acid before bedtime. This helps increase skin hydration, improve elasticity, promote keratinocyte growth, and increase skin thickness. Note that it's not advisable to consume excessive alcohol before sleeping, as alcohol can accelerate sebaceous gland secretion, negatively affect health, and potentially trigger allergic dermatitis or alcohol-induced erythema.

Skin tone depends on the amount and distribution of melanin within epidermal cells, as well as the degree of constriction or dilation of skin blood vessels. These factors are regulated by the neuro-humoral and endocrine systems, with sleep playing a dominant role. During sleep, blood circulation in the skin's capillaries increases, enhancing secretion and clearance processes, while accelerating skin regeneration. We hope this answer has been helpful to you.
