| Improved micro-circulation |
A study found that in 15 women, perfusion in the forehead area increased from ~6.7 PU to ~12.4 PU (≈ +185%) after a 5-minute Gua Sha style massage. |
| Increased skin blood flow & elasticity |
A 20-minute facial massage produced an increase of ~14.0 ± 8.8 perfusion units (PU) (P < 0.001) and skin elasticity improved by ~9.9 % (±4.9 %) after the intervention.

| Reduced daytime sleepiness / improved well-being |
In a 2-month routine of daily facial self-massage (n=62 women), daytime sleepiness decreased 31.2%, and poor-sleep prevalence (PSQI>5) dropped from 71.9% to 49.2%. |
