We spend hours perfecting our beauty regimes, but committing a beauty crime is far too easy.
From foundation lines to overdone brows, these common problems have been fought by all of us at one time or another.
However, it's always good to know you're not the only one who's guilty of a little over-plucking or streaky tanning.
Hairtrade.com conducted a survey to find out the seven most common beauty mistakes and how to avoid them.
This research revealed nine out of 10 British women aged 25-40 made these beauty mistakes everyday and often, the reason was simply not knowing how to rectify them.
A spokesperson from Hairtrade.com said, "We're all guilty of making beauty blunders, but the good news is that it can easily be put right. You might even find that by following some of our top tips you can even save time and money all whilst looking gorgeous."
