- More natural look because the false lash blends with your real lash roots.
- No visible gap between false and natural lashes.
- Better for hooded eyes or deep-set eyes — it opens up the eye without adding bulk.
- More comfortable because the lash band is hidden underneath, so you can't feel it.
- You can wear them with no eyeliner, just a tiny bit of tightline.
STEP-BY-STEP: HOW TO APPLY LASHES UNDERNEATH
- Remove your mascara and clean your lashes completely.
- Hold the lash up to your eye and trim from the outer edge if it's too long.
- Apply a thin layer of lash adhesive to the band and wait 30 seconds until it gets tacky.
- Tilt your head back and look down into a mirror. This exposes the skin underneath your lash line.
- Place the lash underneath your natural lashes, pressing the band against the skin where your lashes grow.
- Use tweezers or your fingers to gently secure the lash in place while the adhesive sets.
- Blink a few times to let your natural lashes sit over the false lash. Then press them together for 10 seconds.
3 COMMON MISTAKES AND HOW TO FIX THEM
- Using a thick lash band — Solution: choose a lash with an ultra-thin, flexible band that hides underneath.
- Placing the lash too high or on top of the natural lash line — Solution: aim for the skin just beneath your lash roots.
- Skipping the tacky wait time — Solution: wait until the adhesive feels sticky (about 30 seconds) before applying.

WHAT TO LOOK FOR IN A LASH DESIGNED FOR UNDERNEATH APPLICATION
Not every false lash can go underneath. You need an ultra-thin band, lightweight fibers, and a natural curl that hugs your own lash line. Thick bands will create a visible seam and feel awkward. The lash must be flexible, barely there, and beautifully minimal.
PHANSTA LASHES are designed with an ultra-flexible thin band that's perfect for underneath application. They feel weightless and blend so well with your natural lashes that no one will know they're there.
