Quick answer: YY lashes vs volume lashes is a choice between supplied structure and fan-making. YY lashes arrive as prestructured, branched units. Handmade volume starts with fine individual fibers that a trained artist forms into fans. YY does not automatically mean lighter, faster or longer-lasting, and volume does not always mean a dramatic finished look.
This comparison is for professional supply selection and for clients who want to understand a service description. Here, “volume” means handmade volume unless stated otherwise. Premade volume fans are a third format, not a synonym for loose individual volume fibers.
YY lashes vs volume lashes: what comes in the tray?
With a YY product, the branch structure is already part of the unit you select. With an individual volume tray, the fibers still need to be organized into the fan required by the professional's plan. That difference affects which decisions are built into the product and which remain with the artist.
Eyelash Excellence's YY product description identifies differences between its original and straight-tipped YY designs. This is useful evidence that a YY name alone does not completely describe the tips. It is manufacturer information, not a test of LASHMAITRE products.
Milady's eyelash-application chapter explains volume as multiple fine fibers formed into a fan, with selection informed by the natural lashes and intended outcome. We use that construction distinction here without converting it into a universal fan-count recommendation.
| Buying question | YY versus handmade volume |
|---|---|
| What is already formed? | YY: a branched unit. Volume tray: individual fibers, not finished fans. |
| Where is shape selected? | YY: choose the supplied structure. Handmade volume: the artist forms the fan. |
| What must be checked? | YY: branches, base and listed specifications. Volume: fiber specifications and suitability for the intended fan work. |
| What does the label not prove? | Neither product name proves total unit weight, appointment time or retention. |
If you mean a single classic fiber rather than a handmade fan, the separate YY versus classic comparison addresses that decision. This page is specifically about prestructured YY units versus individual fibers for volume work.
Choose between a supplied structure and fan-making control
Start with the professional workflow you actually use. YY is a relevant option when the supplied branch pattern fits the assessed design. An individual volume tray is relevant when the artist intends to form fans and wants to choose their shape as part of that work.
Do not use “more control” as a synonym for “better.” A flexible product is only useful when it matches the artist's training and the planned service. Equally, a prestructured format does not remove isolation, placement or assessment from the appointment. This guide is not an application lesson.
For clients, ask whether the displayed reference uses YY units, handmade fans or premade fans. If your artist proposes a different format, ask which aspects of the reference can be preserved and which may change. Similar style names do not promise identical texture.
For artists, use a practical planning question: “Do I want to preserve a supplied branching pattern, or form the fan for this design?” Settle that before comparing tray prices or choosing a diameter. If you want ready-formed volume fans instead, use the separate premade versus handmade fan guide.
Why 0.07mm YY is not equivalent to a 0.05mm volume fan
The two product examples below are not a controlled weight comparison. One is a supplied YY unit labeled 0.07mm. The other is a tray of 0.05mm individual volume fibers; the finished fan's fiber count is not specified by that diameter label.
A label cannot answer the entire loading question. Complete unit construction, fiber count, length, taper, material and base all matter. Without verified measurements, do not calculate a safe fan count or claim one complete unit weighs less merely because its printed diameter is smaller.
The same caution applies to appearance. A close photograph of one tray cannot establish which finished set will look denser on every client. Reference images can help communicate preferences, but they are not matched tests of products, mapping and natural-lash coverage.
Two LASHMAITRE options and their different roles
These public specifications were checked on September 19, 2026. They identify buying options, not a prescription or a claim of physical stock on hand.
Kitten YY Lashes: a prestructured option
LASHMAITRE Kitten YY Lashes lists 0.07mm, C and D curls, single lengths from 8mm to 15mm, and an 8–15mm Mix option. Consider it when the professional has chosen the YY construction and those listed options fit the assessed plan.
Confirm the supplied unit and selected variant rather than assuming every YY tray from every brand has identical branching. The word “Kitten” in a product name also does not prescribe one compulsory eye-shape map.
Premium Volume 0.05mm: individual fibers for fan work
LASHMAITRE Premium Volume Individual Lash Extensions 0.05mm lists C, CC, D and DD curls; single lengths from 8mm to 18mm; and an 8–15mm Mix option. It supplies individual fibers, not a ready-made YY unit and not a packet of finished fans.
Consider this format when the trained artist intends to create volume fans. The available length range is not an instruction to use every length, and this page does not prescribe how many 0.05mm fibers should be in a fan. The broad Volume Lash Trays collection remains the starting point for comparing that product family.
A purchase note that prevents a format mismatch
Before checkout, complete this short note. It is an editorial shopping aid, not a product-performance test.
- Format needed: supplied YY units / individual fibers for handmade fans / premade fans.
- Design requirement: the texture and background fullness the professional has agreed to create.
- Verified options: product name, diameter, curl and length format.
- Unresolved question: any missing unit, base, row-distribution or specification detail to confirm before buying.
One useful comparison starts with the same listed curl and printed length, while acknowledging that construction still differs. Matching those labels does not prove equal weight or identical curl geometry. Its value is keeping the shopping question specific rather than comparing unrelated photographs.
Neither format should be described as allergy-free. The FDA's eye-cosmetic safety guidance highlights irritation and allergic-reaction concerns associated with lash-extension adhesives. Changing the fiber format does not eliminate those concerns.
FAQ
What is the main difference between YY lashes and volume lashes?
YY is supplied as a prestructured branched unit. Handmade volume uses fine individual fibers that the artist forms into fans. The main buying distinction is supplied structure versus fibers for fan-making, not a guaranteed difference in retention or finished density.
Are YY lashes the same as premade volume fans?
Not necessarily. YY describes a particular branching format, while premade volume fans are a separate product category with their own fan specifications. Inspect the actual construction rather than treating the two names as interchangeable.
Does a 0.05mm volume tray contain finished fans?
The LASHMAITRE Premium Volume Individual Lash Extensions 0.05mm listing is an individual-fiber product for professional fan work. Do not mistake it for a finished-fan pack. Check the exact product description when buying other products.
Are YY lashes always lighter than volume fans?
No weight ranking can be established from those names alone. Total unit construction, fiber count, diameter, length, taper, material and base affect the comparison. This guide does not provide measured unit weights or a universal safe loading rule.
Do YY lashes always take less time or last longer?
Neither is guaranteed. A supplied structure changes the preparation task, but the artist's workflow and service plan still matter. This comparison contains no controlled timing or retention test of the two LASHMAITRE products.
Which options should I compare at LASHMAITRE?
Compare Kitten YY Lashes 0.07mm with Premium Volume Individual Lash Extensions 0.05mm only after choosing the required format. YY lists C and D curls; the volume listing also includes CC and DD. Confirm current variants and suitability on the product pages.
Buy the construction your plan requires
YY lashes vs volume lashes is first a format decision. Choose a prestructured YY option when that construction fits the plan, or individual volume fibers when the artist will form the fans. Then compare exact specifications and order details. This avoids buying a familiar name while expecting a different product inside the tray.
