This is not permanent. I had a few of those (i used 30% tcafor 'cross').This is due to premature peeling. Realistically, at this stage, you can't tell it's HYPO (which is not always permanent) until after the redness is gone. Unfortunately, the redness will take months to go away completely. go to your derm asap.

It's best to test one spot first or just do them one at a time. (dcgirl's advice)
