This week we test: liquid eyeliner

Once you get the hang of applying it, liquid eyeliner is the best tool for striking eyes - whether you go for 60s cat eyes or futuristic, blocky lines above and below the eye.

Kanebo Coffret D'or Liquid Gel Liner (HK$130)

The pen-style applicator makes this quick and easy to use. The colour looks natural and it stays for hours without smudging - as long as you let it dry properly after application.

Maybelline Hyper Diamond Liquid Liner (HK$79)

A smooth, gel-like product that glides on and stays put. The subtle sparkle won't look out of place during the day, but play it up at night with a thicker line - or add sparkly eyeshadow!

Clinique Eye Defining Liquid Liner (HK$115)
