So I tested makeup on my face to see what would happen after five months of medication for eczema.
I put on my full makeup starting at 10pm on Friday and kept it all on for an hour before removing it, not with the standard cleansers but with the lotion that my doctor prescribed that I use as a soap substitute and moisturiser. I had also taken an antihistamine and covered my face in medication before starting. I have been using both since.
For 24 hours there was no reaction. My skin was incredibly soft because of all the emollient lotion I had used. In fact, a female friend remarked that I looked as soft and smooth as a baby's bottom (at least, I think she meant it as a compliment!) After 36 hours, though, there was an inflammation at the sides of my neck (where Frankenstein's monster has his bolts). Possibly I hadn't cleansed enough there ... or it's where my wig touches most with its irritant conditioner, or my necklace, or my blouse or my nightie, or maybe I had cleansed by rubbing too hard. Who knows? It's not so swollen and red now after 48 hours, but my chin is a little sore. I continue to monitor. I may try this again next weekend, for longer.
Here's proof. And only another trans person will appreciate the joy of being able to present how you feel.
