Confused About Frosting with at Home TCA Peel

I did my first TCA peel last night - 15%. I've been on Retin-A for three months prior to the peel. The first layer had no frosting after five minutes, so per the instructions that came with the peel, I applied a second layer. I almost immediately got some light frosting around my crow's feet area and in between my eyebrows. At this point, should I have neutralized my entire face, neutralized just the frosting parts, or let the peel continue until 5 min is up or I frosted all over?
