If you've had a pretty raucous party season, a concealer is the ultimate bit of beauty kit to get you looking fresh-faced and fabulous again.
We're all about a good cover up, and, as all self-confessed concealer junkies know, texture and staying power is everything.
As are these three tricks on application and yes, they will change your whole beauty routine. And your life.
1. Always put concealer on over your foundation (you use less and it lasts longer) and blend using your ring finger.
2. Apply in an upside down triangle shape under your eyes (so that the tip faces downwards) rather than dabbing on in dots.
3. ALWAYS have more than one kind of concealer in your make up bag. Guaranteed you'll need different types for different areas of your face so experiment with: liquid, pencil, cream, cover sticks and pens with brush tips.
