Scar/pore treatment timeline: ① mild scars/pores: 4 sessions, 4 months, ② moderate: 6 sessions, 6 months, ③ severe atrophic scars: 8–10 sessions, 8–12 months, ④ maintenance: 1–2 sessions/year. Sessions every 4–6 weeks (skin healing time). Effects build cumulatively — most improvement seen after session 4. Combined herbal medicine + topical care + sun protection essential. Patience required as collagen rebuilding takes time.
