How to Apply Thru Line Waterproof Eyeliner: Step-by-Step

Applying waterproof eyeliner can be tricky if you're not used to it. The key is to work quickly, as the formula sets fast. Start with a clean, dry eyelid. If you have oily lids, a primer can help, but Thru Line is designed to stay put on its own. Hold the pencil at a slight angle and gently pull your eyelid taut for a smooth line.

For a classic look, draw a thin line along your upper lash line, starting from the inner corner and working outward. For a more dramatic effect, thicken the line as you go and create a wing by flicking the pencil upward at the outer corner. Remember, you can always build up the intensity, but it's harder to remove once set, so start light.

• Work quickly—the formula sets in about 30 seconds
• Use short, feathery strokes for a natural look
• Clean up mistakes with a cotton swab dipped in makeup remover

Pro Tips for Long-Lasting Waterproof Eyeliner

Even the best waterproof eyeliner needs a little help to last all day. One of the most effective tips is to set your liner with a matching eyeshadow. Using a small brush, press a bit of shadow over the liner to lock it in place. This also helps to soften the line for a smoky effect.

Another tip is to avoid touching your eyes throughout the day. Oils from your fingers can break down the formula. If you have oily eyelids, consider using a mattifying primer before application. And when removing your makeup, use an oil-based cleanser to gently dissolve the liner without tugging at the delicate eye area.

• Set with a matching eyeshadow for extra staying power
• Avoid rubbing your eyes—blot gently if needed
• Use an oil-based remover for easy, gentle removal
