1. Cleanse and prime the natural lash line to remove oil and residue before beginning.
2. Reference the tray's pre-mapped layout to confirm correct left and right eye orientation before picking up fans.
3. Isolate a single natural lash cleanly before pick-up.
4. Pick up the fan at its flat base, maintaining the mapped orientation so the dual-length strands align in their intended direction.
5. Dip the base lightly in adhesive, using an amount suited to the flat, narrow bonding surface.
6. Place the fan on the isolated lash, positioning it 0.5–1mm from the lid margin, and hold briefly to secure the bond.
7. Allow full cure time, then comb gently with a clean wand to reveal the finished textured, lifted effect.

• Ignoring the pre-mapped left and right orientation — placing fans without checking the map can reverse the intended directional lift; confirm orientation before picking up each fan.
• Using a single curl throughout instead of layering — sticking to one curl option misses the dimensional effect the LB/LC/C/B range is designed for; try mixing curls by layer, such as LC on top and LB on the bottom, for added depth.
• Over-applying adhesive on the narrow flat base — excess product can pool and disrupt the clean bonding surface; use a controlled, light dip suited to the base width.
• Assuming uniform length placement will still create texture — the dual-length effect depends on consistent fan orientation across the set; inconsistent placement can flatten the intended textured look.
• Skipping proper isolation because fans feel quick to place — the pre-mapped, pre-formed structure speeds up application, but incomplete isolation still risks lash-to-lash bonding.

• Fan structure: Dual-length 2D fan, approx. 2mm length difference between strands
• Base type: Long, thin, flat base
• Curl options: LB, LC, C, B
• Length range: 8mm–15mm, including shorter lengths for inner corners and bottom layering
• Material: Soft matte black PBT fiber
• Tray format: Approx. 1,500 fans per tray, 16 rows, pre-mapped for left and right eyes

This is a synthetic false-lash product; no liquid ingredients are used, and no clinical or regulatory claims apply.

How do I decide when to use LC on top and LB on the bottom versus a single curl throughout the set?

Layering LC on top and LB on the bottom works well when a client wants visible dimension and lift without an overly dramatic finish, since the curl difference adds depth while staying subtle. For clients wanting a simpler, more uniform look, sticking to one curl — like C — throughout can still deliver a clean result, just with less layered texture.

What's the fastest way to confirm I'm using the correct left or right orientation mid-application if I lose track of the tray map?

Checking the direction the dual-length strands angle within the fan — since the pre-mapped layout is built around a consistent lift direction per eye — usually clarifies orientation without needing to fully re-reference the tray. If uncertain, comparing the fan against ones already correctly placed earlier in the same eye's set is a reliable quick check.

How do Daisy YY Lashes combine with camellia spikes or classic lashes for a custom hybrid design without looking mismatched?

Using Daisy YY fans as the base texture layer and placing spike accents or classic lashes in specific focal zones — like the outer corner — tends to blend well, since the flat base and consistent curl range integrate smoothly with other lash types. Keeping length transitions gradual between the different lash types helps avoid an abrupt, disjointed look.

Why might the eye-lifting effect look less noticeable on clients with a naturally downward lash growth pattern?

The slanted fiber design is built to work with typical natural lash growth direction, so lashes with a stronger downward-pointing pattern may need slightly more attention to base placement angle to fully achieve the lifting effect. In these cases, double-checking that the flat base is seated to encourage the intended lift, rather than simply following the natural downward angle, helps the effect come through more clearly.

Does the flat base change retention expectations compared to a standard round-based 2D fan?

The wider flat base generally supports a stable bond when paired with a professional-grade adhesive, but as with any flat-based lash, adhesive spread behaves somewhat differently than on a round base and may need a small technique adjustment if you're used to round fiber. If retention feels inconsistent compared to round-based fans, reviewing bead size for the flat base is a reasonable first troubleshooting step.
