what happens to our skin at night?

🌚🌑 At night ( starting from sunset ) ✔️ our skin switches to the repair mode & it focuses more on recovery , regeneration & the production of new ( keratinocytes) skin cells than protection, skin barrier is weaker now & it’s permeable . ✔️ Permeable barrier means things can get in or out . so of course there is a higher absorption rate & at the same time there’s an increase in Trans epidermal water loss ( loss of skin’s water content) & increase in dryness ✔️ The higher absorption rate explains why we shouldn’t sleep with makeup on! . The barrier is permeable meaning it’s likely to absorb most of the ingredients in makeup & the pollutants trapped in makeup . This is why we should never sleep in makeup. Wash your skin with the double cleansing method to make sure your skin is so clean at night . ✔️ At night it’s important to focus on hydrating & moisturizing products to limit TEWL as much as we can . plus focuing on products that offer treatments & repairing for skin like retinol ✔️ Good sleep quality is necessary for skin’s DNA repair , Exposure to artificial light at night decreases melatonin levels & dysregulate the the skin’s circadian rhythm which affects the skin repairing process over time & accelerate aging
