Adding Brightness to Lips for 100 Image sequence

I have a 100-frame sequence in which I want to add bright reflections in the middle areas of a pair of lips.

I am able to track the lips in After Effects and get tracking data fairly well, though the lips a few times change in perspective so it is not perfect.

Given that, what is the best way to add the brightness to, say, frame 1? And then how do I apply that to all the other frames/video?

Btw, dodging doesn't seem to work well.

Thanks.
