UU Lash Extensions — 2D U-Shaped Volume Fans
RY Lashes UU lash extensions are pre-bonded 2D fans built with a U-shaped structure.
Each cluster holds 4 individual lash fibers with flat roots and parallel tips, so lash artists can open perfect fans in seconds with tweezers.
Designed for both beginners and working professionals, these lashes cut grafting time by up to 50% without sacrificing density or finish.
제품명
RY Lashes UU lashes use a U-shaped base to hug natural lashes closely and create a soft, fluffy volume look that feels weightless all day. The parallel sides hold the fan shape open consistently, so every placement looks clean and even — no reshaping, no wasted time.
Made from premium PBT fiber, each lash mimics the texture and weight of natural lashes. The matte black finish blends seamlessly along the lash line with no visible glue residue or white film. Each tray holds 12 rows and removes cleanly with silver foil when the service is done.
These UU fans work for filling sparse areas, building full-volume sets, or speeding up existing workflows. One fan covers the work of three individual extensions at the same density.

- Prep the natural lashes — Cleanse and dry natural lashes fully. Apply primer if used in your service protocol.
- Pick up the fan — Use fine-tip tweezers to grip the flat root of one UU fan. The U-shaped base holds the fan open without extra pressure.
- Dip and place — Dip the flat root into lash adhesive at the correct depth. Place the fan onto an isolated natural lash, 0.5–1mm from the skin.
- Hold and release — Hold for 1–2 seconds until the adhesive grabs. Release and move to the next lash.
- Fill and finish — Use UU fans to fill gaps or build volume across the full set. One fan covers the work of three extensions at the same density.
- Cure and seal — Apply lash bonder or sealant to lock the adhesive and extend retention.
- Remove when needed — Apply silver foil to the bonded area to break down adhesive for clean, damage-free removal.
Q: Are UU lashes suitable for beginners?
A: Yes. The flat root and parallel tip structure make it easy to pick up and place each fan without reshaping it. Beginners can get consistent results from the first tray.
Q: How do UU lashes differ from regular premade fans?
A: UU fans use a U-shaped base instead of a pinched or crossed root. This lets the tips stay open naturally and hug the natural lash line more closely, giving a fuller, more seamless look.
Q: How much time do these save compared to individual lash extensions?
A: Each UU fan applies 2 fibers at once at the same density as hand-making a fan from singles. Most lash artists cut grafting time by around 50%.
Q: What curl and length options does RY Lashes offer?
A: UU lash extensions are available in C curl and D curl, 0.07mm thickness, in both single lengths (8mm–15mm) and mix trays (8–15mm).
Q: What adhesive works best with UU lashes?
A: Use a fast-dry professional lash adhesive with a 0.5–1 second drying time. Volume adhesives work best because they stay fluid long enough to grip the flat root cleanly before setting.
Q: How do I remove UU lash extensions?
A: Apply silver foil to the bonded roots and allow it to break down the adhesive. The fans release cleanly without pulling or damaging natural lashes.
Q: Are these lashes safe for sensitive clients?
A: The PBT fiber itself is non-irritating. Always perform a patch test with the adhesive before a full service for clients with known sensitivities.
Q: How many rows come in one tray?
A: Each RY Lashes UU tray contains 12 rows.
