Your skin has two modes: defense during the day, repair at night. When you skip sleep, you're not just tired — you're actively blocking your skin's ability to heal itself.⁠ ⁠ Here's what one bad night actually does to your skin:⁠ ⁠ Puffiness and dark circles (immediate)⁠ Cortisol spike → collagen breakdown → more oil → more inflammation⁠ Slower wound healing and barrier repair⁠ Worsens acne, rosacea, eczema, and psoriasis⁠ And 7–9 hours of quality sleep triggers collagen synthesis, cell turnover, reduced inflammation, and balanced oil production. That's what makes well-rested skin look plump, clear, and glowy — not a $90 serum.⁠ ⁠ #SleepAndSkin #SkincareScience #DrDustinPortela
