Premade flat base 0.07mm lashes combine the speed of pre-made fans with the superior retention of an ellipse base design — delivering long-lasting eyelash extensions that outperform standard round-base fans in both bond strength and comfort. This guide explains why flat base lashes last longer and how to get the best results.

Why Flat Base Lashes Last Longer
Standard round-base lash extensions bond to the natural lash at a single point — the bottom of the round base. Flat base (ellipse) lashes have a wider, oval-shaped base that contacts the natural lash across a larger surface area, creating a stronger, more distributed bond that resists shedding.
- 30–40% larger bonding surface vs round base fans
- More stable bond — less likely to twist or rotate on the natural lash
- Lighter weight — less stress on the natural lash root
- Natural matte finish — mimics the flat cross-section of real lashes
✨ Promade Lashes Flat Base 0.07mm
Pre-made volume fans with a flat ellipse base — superior bonding surface for longer retention, ultra-lightweight 0.07mm fiber, and consistent fan shape for faster application. Available in multiple densities.

- Round base fans: Standard retention; 2–3 weeks with good aftercare
- Flat base fans: Extended retention; 3–4 weeks with good aftercare; up to 30% longer wear
- Key advantage: Flat base fans are less likely to rotate or lift at the base, which is the most common cause of premature shedding
Application Tips for Flat Base Lashes
- Apply primer before the set — the flat base requires a completely oil-free surface for maximum adhesion
- Use slightly less adhesive than with round base fans — the larger base surface requires less glue to achieve a strong bond
- Place the flat base flush against the natural lash — the entire base must contact the natural lash
- Apply bonder immediately after the set to seal all flat base bonds
Who Benefits Most from Flat Base Lashes?
- Clients with oily eyelids who struggle with retention
- Active clients (swimmers, gym-goers) who need extra bond strength
- Clients with fine or weak natural lashes who need a lighter-weight option
- Lash artists who want to reduce fill frequency for their clients
