Answer first
Avoid strong sun, heavy sweating and swimming in the first days after SMP, as advised on your aftercare sheet. After healing, you can return to normal activities, but long-term sun protection and rinsing after chlorine or sea water help the pigment last.
Early healing
Sweat, chlorine and salt water can irritate healing skin. Follow NPM's timing before returning.
Sun
UV is a main reason pigment fades. A hat or scalp sunscreen outdoors makes a real difference in Malaysian sun.
Sport
Return to light exercise first. Wipe sweat gently, do not scrub.
