Post-workout breakouts aren't from sweat. They're from what happens between the last rep and the shower.
The fact
Sweat plus makeup plus gym-bag towel equals inflammation. Sweat plus a clean single-use pat equals almost nothing.
What to do about it
One Kunbi in the gym bag. Wipe, splash, moisturise. Done.
What Kunbi is
Kunbi 10-pack travel size for the gym bag. Or the 50-pack for home.
