Self Tan Express Bronzing Face Sheet Mask Reviews

I have always been a bit sceptical about self tanning products and I love to do a test patch to check that there will no skin irritations or awkward color/smell since I have a fair and sensitive skin.
With a face sheet mash, there was no possibility for me to test it and I was hoping nothing will go wrong.
I followed the instructions word to word, applying the mask on a dry and clean face, leaving it on for only 5 minutes and massaging the excess serum in my neck and face area. (Note to self, I should have washed the product then off).
The sheet mask itself doesn't have big enough holes for eyes, and so it covered my eyebrows. Otherwise it was really easy to apply and there was no mess.
Big was my surprise when I woke up in the morning and my face and neck were orange. Not carrot orange, but not tanned either. I have been trying to hide from my colleagues throughout the day...
On the positive side, it had no distinct bad "fake tan" smell.
