Ah, Sephora.

A spree in Sephora is an absolute must when on a city break as all beauty fans will know. It's not an over-exaggeration to say it's heaven for makeup lovers, packed full of brands you just can't get at home in Ireland. Of course, it can be a little overwhelming when faced with so much to choose from so rather than panic purchase, it's best to prepare before you go. Researching Sephora's best-sellers and checking out the website reviews is a good place to start and it turns out there's one very popular brow product. Anastasia Beverly Hills Brow Wiz Soft Brown is a huge seller and we're not surprised considering how popular the brand is. According to Byrdie, an estimated 470,000 are fans of the Anastasia Beverly Hills Brow Wiz Soft Brown making it a product people repurchase time and time again. The Brow Wiz has a fine tip and it's the perfect tool for filling in any sparse areas in your brows. It allows for fine, hair-like strokes and the smudge-proof formula means your brows stay put in place all day. It's perfect for when you want to do your brows in a hurry but ensure they're flawless at the same time. The retractable feature is popular as you don't have to sharpen the pencil that way and people adore the Soft Brown shade. We might just have to stock up during the next Sephora trip (if we can wait that long).
