4D Fox-Eye Lift LU is an L-shaped upturned extension designed to create that lifted, fox-eye effect. The angular curl opens up the eye shape and suits clients with hooded or monolids. The LU curl holds its lift through the full retention period.
4D Fox-Eye Lift LU is a professional lash extension designed for certified lash artists working in salons and studios. The fibers are made from synthetic faux mink, which holds its curl and thickness consistently across every tray. Each extension is lightweight and matte black, blending naturally with a client's own lashes.
What sets these extensions apart is the pre-shaped design. Instead of isolating two or three natural lashes and hand-placing individual extensions, the pre-bonded shape lets you build volume faster. This means shorter appointment times without compromising the look your client expects.
The tips are tapered and soft to the touch. They won't feel heavy or stiff on the eye, and they maintain their shape through the full retention cycle. Trays are organized by length, making it easy for artists to pick up the right extension during a set.
These extensions are applied one-by-one to a client's natural lashes using professional lash adhesive. The artist isolates a natural lash, dips the extension base in adhesive, and places it about 1-2mm from the eyelid. This is a semi-permanent service that requires training to perform safely.
Because the design is pre-shaped, the fan or split opens naturally as it's placed. You don't need to spend time hand-fanning — the fibers already have the direction and shape built in. This speeds up volume and hybrid sets significantly compared to classical single extensions.
Lengths range from short to long within each tray. Artists typically mix lengths through the set, placing shorter extensions near the inner corner and longer ones toward the outer corner for a natural lash-line enhancement.
With proper aftercare, extensions last through the natural lash shed cycle, which is typically 4-6 weeks. Clients should avoid water, steam, and oil-based products for the first 24 hours after application. After that, they can cleanse with an oil-free lash cleanser and brush through daily with a spoolie.
Retention depends on several factors: the client's natural lash growth cycle, how well they follow aftercare, and the artist's application technique. Regular fills every 2-3 weeks keep the set looking full.
These extensions are intended for trained lash professionals. They work well for clients who want volume, texture, or a dramatic look without the weight of classic volume fans. They're also a good option for artists looking to speed up their service times.

Can clients wear these at home?
No. These are professional-grade extensions applied by a trained lash artist. They require medical-grade adhesive and proper isolation technique.
How long does a full set take?
Application time varies by artist and set style, but the pre-shaped design typically cuts 20-30 minutes off a standard volume set.
What lengths are available?
Each tray contains mixed lengths. We can also produce custom length trays for bulk orders. Contact us for available curl and diameter options.
