Neck/Chest area (if exposed) - Also some users, including myself have sprayed it under a shirt so when you get close it hits, but I haven’t noticed any differences but I don’t use TUTH too often as I should.
IO/IH - Anywhere skin is exposed, have also used it in the back of my head at times. If anyone tells you you’ll get less self effects, the farther from the body, I haven’t noticed a difference. I’ve used it on neck/back of neck(head)/crook of elbows/wrists/forearms and didn’t notice and differences either. The only thing is in the summer when it’s hot, I’ve found away from places you sweat from prolongs the application spots, so I prefer the arms more for those applications.
So 1 spray to the neck for Instant Shine, IO, or IH would be just fine?
I will be using 1 spray since I just got them and need to determine what works.
Also in the thread about finding your sweet spot…it says don’t use multiple..so if I wanted to use Instant Shine during the day…and possibly TUTH in the evening. Any issues with that?
Depends what I will be doing at the time. If I foresee myself going to the bathroom and washing my hands then I will mostly apply on my arms or neck. Mostly though I find myself spraying everything to the neck since it is convenient for me. As for time phrases, I try to apply within 10 or 15 minutes of an event.
