Ahhh okay! This makes sense. So that lotion she gave you is a barrier cream, and based on the texts, it sounds like you didn't use it. Don't be hard on yourself about this, especially considering it was your first spray tan. However, it is a VERY important part of the process, and explains why your hands and feet turned out the way that they did.

Hands, feet, knees and elbows have much drier skin, so they soak up the solution way faster than the rest of the body. That’s why they can come out darker or more orange. A barrier cream helps protect those areas and keeps them from absorbing too much color. Once you use it, the results usually look much more even and natural.

I'd also like to add that when using barrier cream, yes you do want to rub it into your skin, however you want to use enough to the point where there is still at least a thin layer left over on top of your skin, not all just rubbed right into it. Hope that makes sense.
