Clean Line Liquid Liner vs. Thru Line Waterproof Eyeliner: Which Is Right for You?

When it comes to creating a defined eye look, the right eyeliner can make all the difference. ILIA Beauty offers two standout options: the Clean Line Liquid Liner and the Thru Line Waterproof Eyeliner. Both are formulated with clean, skin-loving ingredients, but they serve different purposes and deliver distinct finishes. In this detailed comparison, we'll break down the key differences to help you decide which one deserves a spot in your makeup bag.

Whether you're a winged-liner devotee or prefer a smudged, smoky effect, understanding the nuances of each formula is essential. From application ease to wear time, we'll cover everything you need to know about these two popular eyeliners, so you can choose the best eyeliner for your needs.

Formula and Finish: What Sets Them Apart

The Clean Line Liquid Liner features a smooth, liquid formula that dries down to a matte finish. It's perfect for creating sharp, precise lines—from a subtle flick to a bold graphic look. The precision tip allows for effortless application, making it a favorite for those who love a classic winged eye. On the other hand, the Thru Line Waterproof Eyeliner has a creamy, gel-like texture that glides on effortlessly and sets to a smudge-proof, waterproof finish. This formula is ideal for tightlining or achieving a softer, more blended look, and it stays put through tears, sweat, and long days.

Both eyeliners are enriched with nourishing ingredients like vitamin E and jojoba oil, ensuring they condition your lashes and the delicate eye area while delivering intense color payoff. The Clean Line Liquid Liner offers a more graphic, high-impact result, while the Thru Line provides a versatile, blendable option that can be built from a subtle line to a dramatic smoky eye.

• Clean Line Liquid Liner: matte finish, precise tip, ideal for winged looks.
• Thru Line Waterproof Eyeliner: creamy texture, waterproof, great for tightlining and smudging.

Application and Precision: Which Is Easier to Use?

If you're a fan of razor-sharp wings, the Clean Line Liquid Liner is your best bet. Its ultra-fine brush tip allows for maximum control, letting you draw thin, precise lines or build up to a thicker wing with ease. The formula is highly pigmented and dries quickly, so you can create your desired shape without worrying about smudging. For those who prefer a more forgiving application, the Thru Line Waterproof Eyeliner's retractable pencil design is incredibly user-friendly. Its creamy consistency glides on smoothly without tugging, and you can easily smudge it out with a brush or your fingertip for a soft, lived-in look.

Both eyeliners work beautifully with ILIA's Angled Line + Smudge Brush, which is designed to help you perfect your technique. This brush features a precise angled tip for creating clean lines and a smudger on the other end for blending, making it a versatile tool for both formulas. Whether you're a beginner or a pro, having the right brush can elevate your eyeliner game.

• Use the Angled Line + Smudge Brush to perfect your liner application and blend.
• For a softer look, apply Thru Line and smudge before it sets.

Longevity and Wear: Which Lasts Longer?

When it comes to staying power, the Thru Line Waterproof Eyeliner is the clear winner. As the name suggests, it's designed to withstand water, humidity, and oil, making it perfect for long days, workouts, or special occasions where you need your makeup to last. It won't budge once it sets, so you can trust it to stay in place from morning to night. The Clean Line Liquid Liner also offers impressive wear time, but it's not waterproof. It will stay put for hours without flaking or fading, but it may not survive a tearful moment or a dip in the pool.

If you have oily eyelids or live in a humid climate, you might prefer the Thru Line for its superior staying power. However, if you're looking for a liner that's easy to remove at the end of the day and don't mind reapplying after a swim, the Clean Line Liquid Liner is a fantastic choice. Both formulas are long-wearing, but the Thru Line's waterproof claim gives it an edge for those who need maximum durability.

• Thru Line is waterproof and smudge-proof, ideal for all-day wear.
• Clean Line Liquid Liner is long-wearing but not waterproof; remove with a gentle cleanser.

Shades and Versatility: Matching Your Style

ILIA offers both eyeliners in a range of shades to suit every mood and style. The Clean Line Liquid Liner comes in classic black and brown, perfect for everyday definition or a bold evening look. The Thru Line Waterproof Eyeliner also features a variety of shades, from deep blacks and browns to rich jewel tones that can add a pop of color to your makeup routine. Whether you prefer a neutral everyday liner or want to experiment with a vibrant hue, both lines have options to inspire your creativity.

For a complete eye look, consider pairing your chosen liner with ILIA's In Full Micro-Tip Brow Pencil to frame your face and define your brows. A well-groomed brow complements any eyeliner style, and this pencil's micro-tip allows for precise, hair-like strokes. Together, they create a polished, put-together appearance.

• Both liners offer a range of shades from neutrals to bold colors.
• Pair with the In Full Micro-Tip Brow Pencil for a complete eye look.

Removal and Skin Care: Keeping Your Eyes Healthy

No matter which eyeliner you choose, proper removal is essential to keep your eye area healthy and prevent irritation. The Clean Line Liquid Liner is water-based and can be easily removed with a gentle cleanser or micellar water. The Thru Line Waterproof Eyeliner, being waterproof, requires a bit more effort. We recommend using an oil-based makeup remover or a cleansing balm to break down the formula without rubbing harshly. This helps prevent tugging and keeps the delicate skin around your eyes looking smooth.

After removing your makeup, follow up with a nourishing eye cream or your favorite moisturizer to hydrate the area. ILIA's skincare products, like the Sun Serum Mineral Sunscreen SPF 50, can be incorporated into your daily routine to protect and care for your skin. Remember, healthy skin is the best canvas for any makeup look.

• Use an oil-based remover for waterproof liners to avoid tugging.
• Always follow with hydration and SPF to keep the eye area protected.

Both the Clean Line Liquid Liner and Thru Line Waterproof Eyeliner are excellent choices, each excelling in different areas. If you love precise, graphic lines and don't mind a non-waterproof formula, the Clean Line Liquid Liner is your go-to. If you need a liner that can withstand anything and prefer a blendable, creamy texture, the Thru Line Waterproof Eyeliner is the winner. Whichever you choose, you can trust ILIA's clean formulas to deliver stunning results while caring for your skin. Ready to elevate your eye game?
