Man, these pics are brutal! Shows the blanching using 25%, then another layer of 30%- this stayed on my skin for a total of less than 4 minutes. Burned like he!!The last 2 pics (which may be in a second post) are a couple of hours later. The spot above my upper lip is where I did a little spot peel last week and I got a cold sore! It healed fast with Abreva.
