They recommend 500 shots by default.
I don't have a face, and I paid in advance.
I just did 300 shots, but it felt like it wasn't enough.
Still, it didn't finish and the shot cut off, so he turned it back on and shot more <
There was no redness or swelling at all
Mask wearing makes me feel a lot hotter than usual.
But it doesn't cause any breakouts or redness.
I'm a super sensitive, allergic, seborrheic skin person, so I'm certifying it.
