My tip for the start (at shoulders):
Initially one should be 3-5 days treat every night. I stopped at third because I shave "had" ... should have to shave rather before the first day ...
Therefore:
Only shave, then one should wait 24 hours (the product bites but good, especially after shaving), then apply and be in the early days of stubble.
I took a cotton pad and have counted droplets, currently I am at 7 droplets per underarm, or in the second shoulder I take a drop less, since the pad still has absorbed what. So it is very thinly on your skin (and even then it can still burn).
I have as I said treated me three days and my shoulders are already dry (just stayed here mid-summer), my whole body smells in the evening after the sun and the typical summer sweat, but my shoulders are still dry. I am speechless by the product and love it :)
Now I'm still waiting on how my shoulders behave with viscose that will shape my final decision. Because I only need 2 hours wearing viscose and already I can smell my own sweat stink ...
