Since we had the conversation on Zoom, I noticed that my skin hasn't been reactive.  It's been 2 and a half years now and I've not noticed stuff going on with my skin. I enclose two pictures, one before we chatted and one done today.  In both pictures, I scratched my skin with my nail to write the word Thank You.  You'll notice that picture one, the skin erupted to see a clear rendering of the word.  In picture 2, you can hardly see the words, although I still felt remnant sensations of irritation.  Hope this is useful to you.

Love your stuff by the way.
