Cleanse gently, moisturize, and wear SPF 50+ daily for 2-4 weeks; avoid sauna, alcohol and vigorous exercise for 48 hours; pause retinoids and acids for 5-7 days — after laser sessions from ₩79,000 (≈ $56) at Kind Global Clinic Myeongdong, with per-spot CO2 crusts left to fall on their own.
A post-laser aftercare routine has one clinical goal in Asian and Korean skin: let the treated zone heal without triggering post-inflammatory hyperpigmentation (PIH), the pigment rebound that careless heat, friction or UV exposure can cause. The routine splits by laser class. After pico toning — the gentlest class, from ₩89,000 (≈ $64) per session — expect mild warmth for 2-6 hours, light makeup from the next morning, and SPF 50+ for 2 weeks. After a 595nm vascular pass like V-Laser at ₩99,000 (≈ $71), redness runs 24-48 hours and heat avoidance matters more than product choice. After per-spot fractional CO2 — from ₩4,900 (≈ $4) per small spot — micro-crusts form within 24 hours and must fall off on their own over 5-7 days, protected by ointment and never picked. Across all classes the constants are the same: gentle cleansing, moisturizer, SPF 50+, 48 hours without sauna, jjimjilbang, alcohol or hard exercise, and actives paused 5-7 days. At Kind Global Clinic Myeongdong the routine leaves with you in writing, and the WhatsApp thread that booked you handles photo check-ins after you fly home.
