Bridesmaid tan disaster - please help!

[BrideFear]

Wedding is Friday. Went for salon fake bake this morning, all smug after proper prep, exfoliation etc.

Washed off about an hour ago. It's about 5 shades too dark (despite a perfect trial) and looks so bad I had to fob off meeting the bride this evening as she'll be really upset. There is also a round white patch on my shoulder which is very visible.

Have googled and seen suggestions like exfoliation, body oil, long baths and swimming to help fade a tan - will any of these do it evenly? Also any advice on what to do with the patch?

Please please help, I am really upset but bride will be much worse!

Thank you!

Go back to the salon, complain and ask what they can do?

Sooper, thanks for reply! Am wondering if the salon can actually do anything other than re-tan the white patch? I don't know if a tan remover lotion exists if it's on for more than a couple of hours ...

These are suggested on a beauty site:

SUGAR & LEMON
Mix together one cup of raw sugar and ¾ cup of lemon juice. Using raw sugar is essential as the rough granules scrub away the tan. Rub the mixture over your skin and leave it to sit for a few minutes. After, rinse off with warm water.

BICARBONATE OF SODA & LEMON
Mix half a cup of bicarbonate of soda (not to be confused with baking powder) with half a cup of lemon juice until a smooth paste forms. Apply to your skin and allow it to sit for a few minutes before wiping off with a cleansing cloth. You may have to repeat this process a few times, but it works!

HAIR REMOVAL CREAM
Want a quick way to remove your glow? Hair removal cream and waxing will instantly strip your skin of your tan, so if you make a mistake, immediately spray a little of the hair removal cream onto the area and wipe off!

Also saw someone mention st tropez do a fake tan removal lotion but thread was very old.

Good luck!

Shower shower shower shower shower shower-Just keep washing it off,plenty of moisturisers inbetween. It should be much better by Friday.
