Just landed on the beauty desk is Poshé Super-Fast Drying Topcoat and, pardon the Ronseal tagline, it does exactly what it says on the bottle. It'll seal your wedding manicure in just five minutes (honestly, we've tried it and it's incredible) so you can be smudge-free ASAP. It's hot from the US and a hit with beauty editors and celebrities alike (it's won five awards in US beauty bible Allure Magazine... plus glossy goddesses Kate Beckinsale and Jessica Simpson are fans). Simply slick it on straight after your second coat of nail polish and if you're having your mani the day before, re-apply a fresh coat on the wedding morning for long-lasting perfection. Buy it now at £8.50 from the brilliant online "beautique" www.cultbeauty.co.uk
