Let me guess what happened. You wore a gorgeous pair of strip lashes, they looked flawless from the top, but then you saw a photo and your bottom lashes looked… invisible? So you ran out and bought a pair of bottom lash extensions. And now you're squinting at them, wondering how on earth to stick these tiny little half-lashes onto your lower lash line with tweezers. You tried once, and ended up gluing your eye shut. We've been there. It is a fiddly process, but once you know the correct technique, it takes less than three minutes and absolutely transforms your whole face. This guide will walk you through the exact process.

WHY BOTTOM LASHES ARE SO TRICKY

Your bottom lash line is curved and constantly moves when you blink. The eye area also produces more oil than the rest of your face, especially in the lower waterline area. This makes adhesion harder. The lash extensions for the bottom are usually individual or small clusters, so you are forced to work with tiny pieces. Most people make the mistake of trying to apply it like a mini top lash, putting it flush against the skin under the eye. That's wrong. Bottom lashes look most natural when applied directly through your natural bottom lashes, not right on the waterline.

STEP-BY-STEP TUTORIAL

STEP 1: PREP THE AREA

You want a completely clean, dry bottom lash line. Use a cotton swab dipped in oil-free makeup remover and gently swipe across the underside of your eye, right where your natural lashes sit. Blot it dry with a clean Q-tip. Make sure there is not a drop of moisturizer or eye cream left. This is the first mistake people make — putting lash glue onto moisturizer. The extensions will slip right off.

STEP 2: THE RIGHT TOOLS

Use a pair of precision tweezers. Not the giant angled ones you use for your brows. Use a pair that comes to a sharp point. You'll also need a piece of tape. Place a piece of medical tape under your eye, angled downwards. This pulls the skin tight, giving you a flat canvas to work on.

STEP 3: PICK UP THE LASH CORRECTLY

Do not pick up the bottom lash by the middle of the band or the hair itself. You'll deform the shape. Hold it by the outer edge of the band, where the lash would taper off and become the shortest. Use your tweezers to gently grasp that tiny end point.

STEP 4: THE UNDER-THE-LASH TECHNIQUE

Apply a very thin line of glue to the bottom strip of the lash extension. Wait for it to tack up. Now, instead of placing the lash on the skin, look up completely. Angle the lash so the band is touching the underside of your natural bottom lashes. Let it blend with them. Press very gently and release. Your natural lashes will support the extension, and the extension will add density and a wispy, full look. Repeat for the other eye.

STEP 5: PRESS & FIX

After the glue sets (about 30-60 seconds), press down with your finger to blend your bottom lashes up into the extensions. This takes away any stark separation.

THE COMMON MISTAKE THAT MAKES THEM LOOK FAKE

People often take the lash and place it right at the water line, below the natural inner rim of the eye. Doing this results in the lash pointing straight out horizontally and looking visibly fake from a mile away. The goal is parity with your top lash, which means the bottom lash should come from the root of your natural lash hair, gently flowing outward and downward just a tad.

WHEN TO WEAR THEM

Bottom extensions are truly a game-changer for specific makeup styles. If you're wearing a full glam top lash, a heavy smokey eye, or trying to achieve a doll-like that 'smaller eye' look from the 60s, bottom lashes are the missing piece. They bring balance to a heavy top lash. But they can look too heavy if you aren't wearing mascara on the bottom. I always recommend applying a touch of waterproof mascara to the bottom lashes first, let it dry, and then apply the extensions over it. This creates a great base for grip.

HOW TO REMOVE BOTTOM LASHES WITHOUT DAMAGE

Never pull them off like a band-aid, especially near the eye. Use an oil-based makeup remover (like a cleansing balm) and soak a cotton pad. Press it closed against the eye for 30 seconds. The adhesive breaks down immediately, and the extensions will slip right off with no tugging. Doing this protects your delicate lower lash hair from falling out permanently.

WHAT TO LOOK FOR IN A BOTTOM LASH

This is a tricky product to arrange well. Many companies just cut a top lash in half and call it a day. That's why they don't stick to the curve. A true bottom lash should be cut differently, with the shortest bits in the center and slightly longer ones on the edges, to mimic the natural diamond shape of your under-eye hair. They should be abundant and densely packed, but very lightweight.

I discovered PHANSTA's designs when I was searching for a pair of bottom lashes that didn't feel like I was sticking a plastic fencing under my eye. The bottom lash collection has specially curved synthetic silk fibers that actually blend into the eye looking hazy and natural. They are one of the few brands I recommend to people who want the convenience of a full set without the $200 extension appointment price tag.
