60% tca peel, possible burn? (Photo)

Hello doctors. I have indian skin on the fair side. I accidentally applied 60% tca instead of my usual 15%(i got to know this later only on my scarring area which are my cheeks. After 15secs it frosted and i washed it off after a minute. Later after frosting subsided , the area where the frosting had occured change to this dark purple brown color. I understand i have made a huge mistake. Im on day two right now. The skin feels a little tighter.What should i expect.cant afford derm visit rn.
