I ripped a piece of napkin, folded it, spilled white distilled vinegar over it, and applied it on my forehead. I pressed the wet napkin on my forehead for 2-3 hours. Some days I would press it for 3-5 hours. When it stung too harsh, I would stop, but would continue after 20 minutes of "rest." This process lasted 2 weeks. Here are the process and results in images:
My experiment commences. I had just finished applying white distilled vinegar for 2 hours. Please note: I censured by eyes to protect my identity.
Directly after applying vinegar, the pimples turn white
When the vinegar dries, the pimples turn black/dark brown.
A few days later
Every night prior to my slumber I would cover my pimples with bandages since some "ooze" came out of the pimples because of the pressure of my head on my pillow.
Peeling beings
Some improvement
Voila!
