Chrono-Beauty: Aligning Skincare with Your Circadian Rhythms
The Science Behind Chronobiology and Skin Your skin isn’t just a passive barrier—it’s a dynamic organ governed by circadian rhythms . These 24-hour biological cycles regulate everything from cell regeneration to barrier function and inflammation. Research from the University of California and Harvard Medical School shows that skin cells express clock genes like BMAL1 and PER2, which influence repair, hydration, and sensitivity throughout the day. Why Timing Matters in Skincare Morning : Skin is more resilient to environmental stressors like UV and pollution. Ideal time for antioxidants and SPF. Afternoon : Sebum production peaks, making it a good time for oil-balancing ingredients. Evening : Skin permeability increases, enhancing absorption of actives.

Hydration and barrier repair peak—use occlusive moisturizers and ceramides. Chrono-Beaut...
