Iolite Eco U YY Lashes – 0.07mm C Curl Mix Tray (8–15mm) | Korean PBT Fiber Volume Lash Extensions

What Are Iolite Eco U YY Lashes?

The Iolite Eco U YY Lashes – 0.07mm C Curl Mix Tray deliver professional cluster-style YY lash extensions crafted from premium Korean PBT fiber. We engineered these extensions for lash artists who want precise, dense, and natural-looking results with significantly faster application. This mix tray includes 0.07mm B, C, and D curls, but the C Curl mix tray focuses specifically on the softest, most natural lift. The unique U YY-shaped parallel micro-flower design replicates the natural growth direction and state of real human lashes — more accurately than any standard YY lash on the market.

Each U YY fan contains four hairs — two on each side. This creates a symmetrical, parallel spread that sits flush against the natural lash line. Consequently, you get a tidy, uniform, and lifelike finish with every single placement.

What Makes the U YY Different from Regular YY Lashes?

Standard YY lashes have two strands that splay outward in a V shape from a single point. In contrast, the Iolite Eco U-YY uses a U YY-shaped parallel design with four strands — two on each side. The tips run parallel to each other rather than diverging at an angle. Therefore, this parallel tip structure more closely mimics the way real human lashes grow naturally side by side, creating a far more lifelike and organic lash line.

How to Apply Iolite Eco U YY Lashes – 0.07mm C Curl Mix Tray

Why the U YY Parallel Design Looks More Natural

Standard YY lashes create a V-shaped splay that can sometimes appear obviously artificial — especially at close range. The U-YY solves this problem with a parallel tip structure that mimics the actual side-by-side arrangement of natural lash growth. When real lashes grow, neighboring lashes do not splay away from each other. Instead, they grow approximately parallel, in the same general direction. The U-YY replicates this precisely. Therefore, the density it creates looks like the client simply has more of their own lashes, rather than wearing extensions. This is Iolite’s single-strand densifying effect — density that reads as natural, not volumized.

Why Flat Roots Improve Every Aspect of the Application

• Better retention: Increased adhesive surface area creates a stronger, longer-lasting bond.
• Smoother lash line: Flat base sits flush, no raised or bumpy attachment point.
• Faster application: Consistent flat base reduces micro-adjustments during the set.
• More natural finish: Flat roots blend into lash line seamlessly, enhancing lifelike appearance.

C Curl — Gentle Lift, Natural Lash Angle

C Curl offers the most natural, subtle lift in the U-YY range. It closely follows the natural upward angle of the lash, so the U-YY extensions blend seamlessly with the client’s own lashes. When combined with parallel tip structure and single-strand densifying effect, you create a barely-there density enhancement that looks entirely like the client’s natural lashes — just fuller.

C curl U-YY is ideal for: clients who prefer everyday natural finish, naturally upward-angled lashes, Asian lash styling where a soft natural look is preferred, and clients who want density without obvious extension appearance.

Why 0.07mm Thickness Works for U-YY Cluster Extensions

At 0.07mm per strand, each individual hair is ultra-fine and lightweight. Four strands at 0.07mm grouped together remain comfortable on the natural lash without causing excess weight or stress. Perfect for clients wanting denser look without heavy extensions, those with fine or moderately sparse natural lashes, natural density effect goals, and artists wanting fast density without compromising lash health.

Storage and Professional Use

Storage: Keep tray in a cool, dry place away from direct sunlight. Humidity and heat can affect fiber’s curl memory and woven base integrity. Always close tray when not in use.

Caution: For professional use only. Keep out of reach of children. Perform a patch test for clients with adhesive or fiber sensitivities before full application.
