The complete day-to-night lash growth system for longer & healthier lashes. Complete with a money-back guarantee.
Clinically proven, the Lash Growth Duo is created to work in sync around the clock, day to night; peptide-powered serum by day, restorative lash oil by night. Together, they deliver visibly longer, healthier, and stronger lashes - for optimal results at every stage of the lash cycle.
Most lash products focus on stimulation alone. This is the system that goes further.
By supporting the follicle by day and conditioning the lash fibre by night, the Lash Growth Duo helps results appear, and actually last. Growth that looks better, feels healthier, and doesn’t compromise the eye area.
Suitable for sensitive eyes, both formulas reflect BBB London’s commitment to clean, considered ingredients. No harsh shortcuts. No unnecessary fillers. Just thoughtful formulations designed for long-term lash growth & health.
Supports the full lash growth cycle, not just a singular phase
Targets both the follicle & the lash fibre
Helps reduce breakage over time
Gentle enough for daily use, even with sensitive eyes
Designed for results that improve with consistency
Every ingredient in the Lash Growth Duo earns its place. Nothing added for hype. Nothing included without reason.
Lash Boost Serum (Day)
Powered by peptides and conditioning actives that support the growth phase of the lash cycle. Lightweight, fast-absorbing, and designed to sit comfortably along the lash line without irritation.
Luscious Lash Oil (Night)
A restorative blend of nourishing oils and conditioning ingredients that work overnight to soften, protect, and strengthen lashes as they repair. Helps maintain flexibility and reduce breakage as lashes grow.
Both formulas are:
Clean and carefully formulated
Free from harsh or unnecessary ingredients
Suitable for sensitive eyes
Because healthy growth should always feel calm.
1. Apply Lash Boost to your lash line (both top and bottom) every morning. Ensure lashes are clean for best results.
2. Using the mascara wand, apply the Lash Oil onto eyelashes as part of your evening routine.
Longer & stronger lashes in 8 weeks, guaranteed.

"Too many lash serums chase growth and stop there. The lashes grow, but they don’t last, because they aren’t strengthened along the way.
I created the Lash Growth Duo to work with the lash cycle, not against it.
Supporting growth by day, restoring lashes by night, it treats lash growth as a complete system, not a single step.”

The duo is designed to support the entire 360° lash cycle by combining our peptide-led serum for growth by day and our nourishing lash oil at night for restorative care that encourages strong & healthy growth that lasts.
We guarantee that you'll see longer & fuller lashes in 8 weeks or less, or your money back.
