Sleep Optimization (7–9h)
Sleep deprivation makes you measurably less attractive to observers. The cheapest glow-up available.
Evidence grade A
Multiple randomized controlled trials / meta-analyses
Mechanism
Sleep loss causes periorbital edema, darker under-eye circles, paler skin, and drooping eyelids; chronic loss elevates cortisol, degrading skin and body composition.

Under-eye appearance — a core Mavqen feature metric — responds within days to consistent sleep. Fix schedule regularity first, then environment (dark, cool), then screens.
