I purchaced 25% tca peel from skin obsessions. This is first tca peel I have ever done. I have done lactic/glycolic peels in past. Researched tca peels and did everything by the book. My face frosted just fine after several minutes and I let sit. But in area that I wanted deeper peel (white patch) I applied second coat it instantly started to frost to a white not gray like rest of face so I neutralized instantly. Is this normal? Will it go away?
