Night vs. Day: What Your Skin Actually Needs at Different Times

Understanding Your Skin's Circadian Rhythm

Your skin, like your body, operates on a 24-hour circadian rhythm that impacts how it functions during the day and at night. During the day, your skin's primary role is protection: shielding itself from UV rays, pollution, and oxidative stress. At night, it shifts to repair mode, focusing on cellular regeneration, reversing daily damage, and strengthening its natural barrier.

What Happens to Skin During the Day?

• Increased Sebum Production: Your skin tends to produce more oil, which helps to maintain moisture but can also contribute to clogged pores.

• Environmental Exposure: Your skin is exposed to sunlight, pollution, and blue light from screens, leading to oxidative stress and potential inflammation.

• Barrier Protection: The skin’s barrier functions at its strongest, making daytime the best period for using antioxidants and sun protection to support its defensive role.

What Happens to Skin at Night?

• Cellular Renewal: Your skin’s cell turnover increases, allowing dead skin cells to shed and new ones to form.

• Increased Blood Flow: This enhances the delivery of oxygen and nutrients to skin cells, supporting repair processes.

• Increased Permeability: The skin becomes more permeable at night, allowing it to absorb active ingredients more effectively.

How to Care for Your Skin During the Day

To align with your skin’s protective function during the day:

• Cleanse gently to remove oil build-up from overnight while preserving moisture.

• Ingredients like Vitamin C neutralize free radicals and protect against pollution and UV damage.

• Hydrate with lightweight moisturizers that support barrier function.

• Sunscreen is crucial in preventing UV damage and premature aging.

How to Care for Your Skin at Night

To align with your skin’s repair mode at night:

• Double cleanse to thoroughly remove sunscreen, makeup, and pollutants.

• Using active ingredients like Retinoids, peptides, and gentle exfoliants can enhance cellular turnover and repair.

• Night creams with humectants and occlusives seal in moisture and support barrier repair.

• Night is the perfect time for addressing hyperpigmentation, fine lines, and dullness.
