Use an Oil
If you plan on exfoliating the tan off, first use an oil on dry skin, and leave it on for a few minutes to absorb. This will help break down the tan so that when you start exfoliating, it won't require as much scrubbing. You can also try soaking in bath, adding all the oils you have. These oils plus the bath water will help break down the tan before you exfoliate.
Ever got a fresh tan before shaving your legs and found that the color seems to come off with the hair? That's because it does: shaving gives your skin an extra exfoliation. If you're looking to remove your tan quickly, every little bit of exfoliation helps, so shaving can be a good option.
Head Into a Steam Room
There's nothing like a good old sweat session to remove stubborn tan. This might not be an emergency tip, but if you're going to the gym, a good session followed by a sweat will help get rid of the product.
Try Lemon Juice
You've probably heard from someone on a few occasions that lemon juice is great at removing tan, and it is — just make sure to do a spot test first to ensure it doesn't irritate your skin. Apply all over the areas you want rid of the tan, wait until absorbed, and remove with a flannel. If that's not working as well as you'd like, warm the lemon juice up a little. Just make sure it's not too hot.
And if all else fails, try one of these self-tanner removers, ahead.
