You're spending $200 on serums but sleeping 6 hours. Which one is the problem?
During Stage 3 deep sleep, growth hormone is released at its daily peak, driving maximum skin cell repair and regeneration. Poor sleep elevates cortisol, which directly breaks down collagen. A single night of 6 hours of sleep reduces skin barrier repair by 30% — equivalent to not applying any moisturizer.
Seven to nine hours of quality sleep produces visible skin improvement within 2 weeks, comparable to the timelines of most topical treatments.
