If you've ever watched someone apply lash strips on top of their lashes and thought, “That dark line looks like a miniature dead caterpillar,” you need to try under-liner application. It's the technique that hides the band completely. No adhesive streaks. No obvious edge. Just lash that looks like it grew out of your eyelid.

WHY APPLY LASHES UNDER YOUR EYELINER?

Under-liner application means placing the lash strip under your top lash line, then using eyeliner to seal the band. The payoffs are huge. First, the lash band sits exactly where your natural lashes originate, so it moves and blinks with you. Second, the liner covers the band from both angles, so no matter how close someone leans in, they don't see a fake. Third, this method opens up a shallow lash line, which is a godsend for hooded eyes and for anyone who has been told “you can't wear strips.”

WHAT YOU NEED BEFORE YOU START

• An angled liner brush
• A gel or cream liner (not felt-tip, you need a bit of glide)
• Tweezers or a lash applicator
• A compact mirror you can angle at your chin
• A full lash strip or individual lash clusters (thinner bands work best)

STEP-BY-STEP: THE UNDER-LINER METHOD

1. Apply a thin layer of eyeliner to your upper waterline and also draw slightly onto the underside of your upper lash line.
2. Hold your lash strip up to your eye and trim any extra length from the outer edge, never cutting the inner side.
3. Put a thin, even layer of lash adhesive on the lash band and wait 20 seconds until it's tacky.
4. Use tweezers to place the band right underneath your natural lashes, pressing upward into the lash line.
5. Close your eye halfway for 10 seconds to set the curve.
6. Go back with more gel liner and run it along the waterline to sandwich the lash between the liner layers.

If your lash won't stick, wait only 10 seconds after applying adhesive instead of 20. If the band still shows, you skipped the second liner coat. If it pokes your inner corner, trim the outer edge at a slanted angle.

WHAT TO LOOK FOR IN A LASH FOR THIS TECHNIQUE

Under-liner application works best with lashes that have flexible, low-profile bands. The classic plastic band is too stiff and will fight your eye curve. Look for slimmer cotton bands and individual cluster lashes so you can build just the right thickness. A little bit of length variation across the band also helps the blend.

UNDER-LINER LASH FAQ

Can I use lash glue under my lashes?

Yes, but use a razor-thin layer and wait until it's tacky. If you apply too much, you risk getting adhesive on your waterline.

How long do lashes stay on when applied under liner?

The sandwich technique usually makes lashes last 8 to 12 hours. The liner holds the band from both top and bottom, so there's less edge to lift.

Does this technique work with hooded eyes?

It's actually the best method for hooded eyes. Because the lash sits below the natural lash line, it extends the visible lash area without pressing against the hood.
