Tanning help

I work at a dog shelter and yesterday we had particularly aggravated doggo who scratched at me like a bear to a tree.

I normally wouldn’t mind however I have a wedding next week and have a spray tan booked for Monday.

The scratches have started to scab and I am worried that the spray tan wont go well on the scabs.

Is there any way I can fast-heal scabs so that tan doesn’t go all streaky?

Would appreciate any tips😩😩
