Red Spot After 50% Tca Peel?

Roughly 2 weeks ago I used a 50% TCA on my face until it whittened up then I washed it off. Now one side of my face seems to be back to normal with little to no redness at all. The other side however, has a red spot on it still (about the size of my thumb nail). Does anyone know why? Or maybe how to reduce redness? Possibly when it will completely heal back to normal color?
