7. Know you can fix it
Too much? Don't panic. "Remove excess self-tan from your hairline by simply applying makeup remover to a Q-tip and rubbing along the hairline to even out the color," advises Read. If you're too dark all over but you've recently applied, know that faux tans have a time before it truly sets in—usually about 4-6 hours. "Buff away the streaks with a makeup brush or kabuki brush. What you are seeing when you see the streaks, spots, etc. is not usually not the DHA but just the bronzer on top, which is essentially makeup and is easy to fix," says Feller. "Take your powder brush and start blending—that will set the bronzer back into place and no one will know!" If you're too late, don't freak out just yet. Call your local salon and make an appointment for a fix. Pros—they know what they're doing.
