Yeah I have experience with this substance, I use it for an allergic reaction if I ingest something with propylene glycol. I’ve used it excessively and I wouldn’t recommend lt, I had achy joints and to my understanding it absorbs vitamins & nutrients as well. If you were to use it I would use it sparingly.
Now it does work really well for my acne, I make a paste and use it for the acne on my forehead once a day and it dries it right up.
