If you've ever struggled with dry, flaky lips that never seem to hold color, you're not alone. The Trinny London Lip Reset Kit is designed to give your lips a fresh start, combining treatment and definition in one easy-to-use duo. Whether you're prepping for a bold lip or just want everyday softness, this kit has you covered.

In this guide, we'll break down exactly how to use each component of the Lip Reset Kit, share tips for getting the most out of your lip care routine, and explain why this duo is a game-changer for smoother, healthier-looking lips.

What's in the Lip Reset Kit?

The Lip Reset Kit is a two-step system that works together to redefine and moisturize your lips. It includes the Sheer Joy lip oil, which provides a 24-hour non-sticky moisture boost, and the Line2Define Lip liner, known for its ultra-creamy, long-wear formula. The kit also comes with a complimentary Elizabeth bag, making it perfect for on-the-go touch-ups.

The idea is simple: treat first, then define. The oil works to soften and hydrate, while the liner helps you map your lip shape or wear as an all-over base. Together, they deliver effortlessly redefined, glossy lips that last.

  • Line2Define: creamy, long-wear definition
  • Complimentary Elizabeth bag for travel

Step-by-Step: How to Use the Lip Reset Kit

Using the Lip Reset Kit is straightforward, but a little technique goes a long way. Follow these steps for the best results, whether you're prepping for a full makeup look or just want a quick lip refresh.

Start with clean, dry lips. If you have any dead skin, gently exfoliate with a soft toothbrush or a lip scrub (you can make one with sugar and honey). This ensures the oil can penetrate deeply.

Apply a few drops of Sheer Joy lip oil to your lips. Massage it in with your fingertip or the applicator, allowing it to absorb for a minute. This step hydrates and creates a smooth canvas.

Next, take the Line2Define Lip liner and outline your lips, starting from the cupid's bow and working outward. The creamy formula glides on without tugging, so you can easily correct mistakes. For a fuller look, slightly overline just the center of your lips.

Fill in your lips with the liner for an all-over base, or leave the outline and apply your favorite lipstick on top. The liner also works beautifully on its own for a matte, long-lasting finish.

Finish with a second layer of Sheer Joy for extra gloss and hydration. This locks in moisture and gives your lips a healthy sheen.

  • Always start with exfoliated lips for better absorption.
  • Use the liner tip to define, then fill for a base.
  • Layer the oil after the liner for a glossy finish.

Common Mistakes to Avoid

Even with a great product, common mistakes can hinder your results. Avoid these pitfalls to get the most out of your Lip Reset Kit.

Skipping exfoliation is a big one. Dead skin cells can make the liner skip and the oil sit on the surface instead of absorbing. Also, don't apply the oil to wet lips—it won't adhere properly.

Another mistake is using the liner on dry lips without any prep. This can cause tugging and uneven application. Always hydrate first with the oil or a balm.

Finally, don't overline too much. A subtle overline enhances your natural shape, but going overboard can look unnatural, especially in photos.

  • Exfoliate regularly, but not more than twice a week to avoid irritation.
  • Apply the oil to dry lips for best absorption.
  • Use a light hand when overlining.

Why the Lip Reset Kit Works

The Lip Reset Kit isn't just about instant results—it's about long-term lip health. The Sheer Joy oil is formulated to provide 24-hour moisture, which helps prevent dryness and flakiness over time. Meanwhile, the Line2Define liner's castor oil-infused formula ensures smooth application without drying out your lips.

Together, they create a routine that treats and defines, making it easy to maintain soft, smooth lips every day. Whether you're a makeup minimalist or a full-glam enthusiast, this kit fits seamlessly into your routine.

  • Long-term hydration prevents recurring dryness.
  • The liner's creamy formula doubles as a base for lipstick.
  • Perfect for quick touch-ups with the included bag.
