Like your sleep, the skin’s internal clock is determined by signals sent to your brain’s master clock. This master clock takes in various factors and determines when your skin produces sebum, fixes your skin barrier, and protects against outside aggressors. According to Rosafa Skincare, this function of the skin is no different from the job the master clock performs for other aspects of the body. Based on what we know about circadian rhythms and the skin’s internal clock, during the day, your skin works to increase its sebum production, protection, pH, and recovery of the skin’s barrier. At night, your skin works to repair and regenerate new skin cells.
Prevention mentions that just like outside factors can interrupt your internal clock when it comes to sleep, your lifestyle habits can also interrupt your skin’s internal clock. Factors like blue-light exposure, stress, and unhealthy eating habits can interrupt your skin’s clock and the essential functions it conducts. By interrupting your skin’s clock, your skin isn’t protecting or regenerating itself as it should, which can help cause acne or other skin issues. This internal clock in your skin is why many suggest eating healthy, exercising, and getting a good night’s rest if you want better skin. To use your skin’s internal clock to hack your skincare routine, you need to ensure your internal clock is well-regulated.
