Some lashes refuse to be corrected by a simple straight base. LU adds a deeper, U-like bend near the root before the tip rises, which gives it more leverage over lashes that grow stubbornly downward or sit deep under a heavy lid.
Where the deeper bend helps
- Strongly downward-growing natural lashes that need the root itself redirected.
- Deep-set or hooded eyes, where the lid can hide a standard lifted tip.
Eye structure is the deciding factor here, not just lash direction. The notes on lashes for hooded eyes explain how lid shape interacts with curl, and the curl types guide places the deeper bend among its neighbours.
To compare all the specialty options at once, the shop by curl hub is the reference. LU is the one to consider when the problem starts at the root rather than at the tip.
What makes LU different from L?
LU adds a deeper U-like bend near the root before the tip rises, where L keeps a simpler straight base with a turn at the end.
Is LU specifically for hooded eyes?
It is often chosen for deep-set or hooded eyes and stubborn downward lashes, but lash direction and lid shape are assessed together.
When should I consider LU over LD?
When the issue is at the root and the lid still hides the lift. LU gives more structural redirection before the tip turns up.
