About Skin Microbiome & Sleep

Learn what is the impact of regular late sleeping on your microbiome, skin functions and appearance.

Are you regularly going to bed late?

Have you ever wondered what it means to your skin and its microbiome?

We all know that an unhealthy sleep pattern influences circadian rhythm, and negatively affects general health. But what about the skin and its functions? The facial microbiome of over 200 Chinese women, aged 18–38 years and living in Shanghai, was investigated. All of them had one thing in common, late bedtime routine.

What were the results?

Physiological parameters have changed

• significant decrease in skin hydration content, firmness and elasticity,

• significant increase in TEWL, sebum production and wrinkles appearance

• impaired the integrity of skin barrier, damaged skin structure, and disrupted water–oil balance.

Microbiome balance was disturbed

• reduced both the abundance and the diversity of facial bacterial microbiota.

• the abundance of Pseudomonas increased significantly, while Streptococcus, Stenotrophomonas, Acinetobacter, Haemophilus, Actinomyces and Neisseria decreased significantly.

• Elevated ration ratio between Cutibacterium and Staphylococcus is believed to negatively affect the skin homeostasis.

• the abnormal variation in the abundance of Staphylococcus species (S. epidermidis and S. aureus) has been suggested to cause atopic dermatitis, sensitive skin, acne vulgaris and dandruff.

• elevated abundance of Pseudomonas may aggravate the damage to the skin barrier and negatively correlated with skin hemoglobin content, melanin content and skin hydration.

What is the bottom line of the study?

Regular late bedtime not only damages the skin barrier and skin structure but also reduces the diversity and composition of facial bacterial microbiome.
