The Blueprint: How Lashify Engineered the Original Cluster Lash

Updated October 2026 · 9 min read

Search “cluster lashes” today and you'll find hundreds of them. Different names, different packaging, different prices. Almost all of them share the same idea: many tiny clusters joined into one segment, worn at home, without a salon. That idea has a beginning. It was drawn up in 2016 by Lashify founder Sahara Lotti, launched in 2017 as the Gossamer®, and protected ever since by more than 700 patents and registrations worldwide.

This is the blueprint: what goes into an original Gossamer® lash, why every part was engineered the way it was, and why the copies never quite feel the same.

There are cluster lashes. And then there is the lash every one of them was modeled on.

Before the blueprint: clusters were a salon product

Before 2016, clusters and flares belonged to lash artists. A professional glued them onto your lash line one at a time, with salon adhesive, in an appointment. Doing it yourself, in a mirror, was close to impossible. Strip lashes were the only real home option, and everyone knows their trade-offs: a visible band, a heavy feel on the lid, and corners that lift by the end of the night.

Sahara wanted something that didn't exist: lashes that looked like a salon set, felt like nothing, went on in minutes at home, and came off without a fight. Building it took two years and four inventions that only work together.

The four parts of the blueprint

1. The Spine™: a base engineered to disappear

Most lashes are held together by layers of fiber and glue. A Gossamer® isn't. Its base, the Spine™, is heat-fused: the fibers are fused together with heat during manufacturing instead of being stacked and glued. The result is a base that is thin, flat and light, so it vanishes under your own lashes instead of sitting on your lid like a band.

Heat-fusing a lash base was a completely new way to make lashes, and it became Lashify's signature. As the range grew into fuller volume styles, the process was refined again so that denser lashes keep the same thin, comfortable spine as our most natural styles. In 2023 came GripTex™, a flat, textured spine that interlocks with your natural lashes like a zipper for more surface contact and longer wear.

2. Underlash Technology®: worn under, not on top

Here is the part that changed everything. A Gossamer® is placed under your natural lashes, not glued on top of the lash line. Your own lashes rest on it and hold it. The spine disappears from view, your lid never carries a band, and the lash moves with you because it's part of your lash line rather than something stuck to it. The method of applying a lash this way is itself patented.

3. Bond and seal, not glue

Traditional lash glue is designed to set hard. Lashify bonds were designed to do the opposite. Built on Micro-Flex™ technology, they form a soft, flexible cushion around the natural lash and use polymer attraction to hold, so the lash bends and moves naturally instead of locking stiff. Then you seal it: a sealer such as Water Poof™ locks the bond in and adds hold through water, sweat and humidity. When you're ready for a new look, a remover dissolves the bond and the lashes slide away. No pulling, ever.

Lashify bonds are now made in the USA by Lashify Labs, and each one is designed for a specific way of wearing lashes. Read the full guide to bond and seal →

4. The Fuse™ Control Wand: one tool, one clean fuse

The final piece is the tool. The patented Fuse™ Control Wand places each Gossamer® and then fuses it to your lashes with a horizontal Clamp Force™ that presses the lash and your natural lashes together evenly along the whole spine. Wandom® covers keep the tips tack-free. Fusing is the step that turns a lash you're wearing into a lash that's part of you, and it's the step the copies leave out.

The lightest lashes in the world

Every decision in the blueprint points the same way: lighter. Most lashes are made by gluing fibers together, and that glue adds weight, stiffness and a shiny base you can see. A Gossamer® is made without glue. Its ultra-light Korean PBT silk fibers are heat-fused into the Spine™, so there is nothing in the lash weighing it down. That's why Gossamers are the lightest lashes in the world: weighed side by side against other brands' lashes in patent litigation, the Gossamer came out the lightest.

Gossamer® lashes are built with patented technology that needs no added material at the base to hold the fibers together. Each lash is so light it falls below what conventional scales can measure. Many lower-cost lashes rely on extra base material, which adds weight, thickness and stiffness.

The rest of the design keeps it that way. There's no band on the lid. And because each Gossamer® is a segment that sits under many natural lashes, its weight is spread across your lash line instead of hanging from a single point. The result is the feeling clients describe again and again: they forget they're wearing them.

Made beautifully enough to wear again

Cheap lashes are disposable because they're built to be. A Gossamer® is built to last. The heat-fused spine holds its shape, the fibers hold their curl, and because the bond dissolves with a remover instead of being torn off, the lash comes away intact. Clean your Gossamers gently, let them dry, store them back in their cartridge, and wear them again. Here's how to clean them →

That's what quality means to us: a lash made well enough that you want to keep it.

More looks than anyone else makes

Because Lashify designs the lash, the bond and the tools as one system, we can make far more of it. There are more than 30 Gossamer® styles, from the softest natural flutter to the loudest volume, in a wide range of lengths and colors, plus pre-mapped sets with every length already placed. See every style →

• Most natural: Amplify and Curl
• Soft volume: Fluffy and Plushy
• Decided for you: Pre-Mapped Gossamer® lashes

Protected by more than 700 patents

Lashify holds more than 700 granted patents and registrations in 32 countries and the European Union, with the first granted on June 5, 2017. In the United States, the lash itself is covered by a family of patents titled Artificial Lash Extensions, beginning with No. 10,660,388. The underlash method of applying it is its own patent, No. 11,330,855. Stacking, the Fuse™ Control Wand and the bonds are patented too. The full list is public, because we think you should be able to check. See all the patents →

How to tell the original from a copy

	The original Gossamer®	Typical copies
Base	Heat-fused Spine™: thin, flat, no glue layers	Fibers glued into a thicker base
Placement	Under your natural lashes (patented method)	Often on top of the lash line
Hold	Flexible bond, fused and sealed	Glue or a single bond coat
Tool	Patented Fuse™ Control Wand with Clamp Force™	Tweezers or a basic applicator
Removal	Remover dissolves the bond; lashes slide off	Often pulled or picked off
Wear again	Made to be cleaned and reused	Usually disposable
Weight	The lightest in the world: no glue in the lash	Glue in the base adds weight
Range	30+ styles, lengths, colors and pre-mapped sets	A handful of styles

Questions people ask

What are cluster lashes?

Cluster lashes are segments of lash fibers worn along the lash line. The multi-cluster lash you apply yourself, with many clusters joined on one spine and worn under your natural lashes, is the Gossamer®, invented by Lashify in 2016.

Who invented the multi-cluster lash?

Lashify founder Sahara Lotti invented the patented multi-cluster underlash system in 2016 and launched it as the Gossamer® in 2017. Clusters and flares existed before as a salon product; the multi-cluster lash you apply at home is Lashify's invention.

What are Gossamer® lashes made of?

Gossamer® fibers are made from ultra-light Korean PBT silk, joined on a heat-fused Spine™ base instead of being glued together, which keeps the base thin, flat and light.

What are the lightest cluster lashes?

Lashify Gossamer® lashes are the lightest lashes in the world. Most lashes are made by gluing fibers together, and the glue adds weight and a visible base. Gossamers are made without glue: the fibers are heat-fused into a thin Spine™. Weighed side by side against other brands' lashes in patent litigation, the Gossamer came out the lightest.

Are Lashify lashes reusable?

Yes. Gossamer® lashes are made to be worn again: remove them with a remover so they slide off intact, clean them gently, let them dry and store them in their cartridge.

How long do Lashify lashes last?

Apply once and wear them for days. With the bond layered the Lashify way, clients wear a set for up to 2 weeks.

Do cluster lashes need bond and seal?

For Gossamer® lashes, yes. The bond holds the lash to your natural lashes, fusing with the Fuse™ Control Wand locks it in, and a sealer adds hold through water, sweat and humidity.
