Stay All Day Muted Neon Liquid Eye Liner, mellow yellow

There is nothing quite as satisfying as a graphic liner that lands on the first try and stays put until sunrise. Stila has reimagined its fan favourite with this muted neon collection - softer than traditional neons but bolder than your everyday neutral - and mellow yellow is one of those shades you'll reach for time and again. It starts with an ultra-fine felt tip that feels delicate in the hand, laying down just enough pigment so even a beginner can pull off something stunning without the usual liquid liner anxiety about getting it wrong. You can keep it subtle as a thin lash line or build up to a dramatic bold wing by applying pressure at an angle - and every drop stays precisely where you put it because this formula is quick-drying, waterproof, and transfer-proof for up to 12 hours. That's the difference between your liner looking fresh at midnight after a festival set rather than smudged on your eyelid. Mellow yellow works as a statement colour but also lands beautifully in daytime looks when you just want something unexpected. Whether it is summer concert season, heading out late or creating a special makeup look for a friend's birthday, this pen delivers without skipping or pulling anywhere. Shake well before use and keep it horizontal between applications to get the best performance every time. It will quickly become one of those products in your kit you trust implicitly because it actually does what it says - gives you a clean line that lasts all day and never budges. Try it yourself and add some mellow yellow to your routine this season.
