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

what happens to our skin in the morning?

Skin’s circadian rhythms ( natural processes & functions ) Are changes in skin’s functions that follow a 24-hour cycle & they are mainly affected by day & night . light & dark ✔️ Understanding how skin changes throughout the day, help us use skin care products at their most effective times Part (1) our skin in the morning : ✔️ During the day ( starting from sunrise) 🌕🌝 your skin switches to the protection mode , it works hard to protect itself ✔️ The rate of transepidermal water loss (TEWL) is lower, your skin’s doesn’t loose water content during the day as much as night because during the day it produces more oil to make a film on skin that strengthens the barrier to protect you from pollutants, irritants & free radicals. ✔️ So you shouldn’t be stripping your skin during the day by using harsh cleansers or exfoliation . by doing this your skincare doesn’t work in harmony with your skin’s need . ✔️ during the day your skin faces too much stress protecting you from pollution, irritants , uv rays & free radicals, so it’s important to use antioxidants & sunscreen to support your skin’s function at this time ✔️ it’s not the perfect time for trying new products for two reasons : (1) your skin is already stressed during the day as it’s protecting you (2) your body’s cortisol levels rise up at morning , high levels of cortisol makes skin more sensitive & reactive so it’s likely to have a reaction from new products . ✔️ skin absorbtion is lower at the morning . the protection mood & the strong barrier during the day time makes skin less permeable so maybe you can not layer many products as in the evening. At morning just focus on the important & basic products ( wash with water or gentle non stripping cleanser , don’t exfoliate, use antioxidants, sunscreen, and a good moisturizer to support your barrier function )
