Your lashes already know how to grow. Growth factors , carried by extracellular vesicles , help support your lashes' natural growth cycle.

Lash growth starts with a conversation.

Hair follicles respond to signals from surrounding cells.

Growth factors are the cell-to-cell signals.

IGF-1 and FGF-7 participate in pathways linked to follicle-cell growth and survival.

Extracellular vesicles are nanoscale bubbles that carry those signals

from one cell to another within a protective membrane.

Premium Rejuvenation Eyelash Serum

We combine these ideas in one lash formula,
then study its performance in people.

From biology to daily lash care.

Our clinical study results.

At week 8, the between-group gap in mean change was 14.70 percentage points for length and 5.38 for density.

The research behind
the thinking.

Hair biology informs our approach. The animation illustrates selected mechanisms, not a measured delivery pathway in this product. Scalp and ingredient studies provide context; our lash-formula results are presented above.

01

Hair & scalp clinical trial

A combination, explored in people.

A 56-day randomized exploratory trial in 60 adults compared five scalp formulas. The combination of Centella vesicles, IGF-1 and FGF-7 showed improvements in hair measures versus placebo. This was a different scalp formula, not this eyelash serum.

IGF-1 · experimental research

Understanding the growth phase.

Research in cultured human hair follicles examined IGF-1 and reported enhanced hair growth and maintenance of the growth phase. This supports a biological rationale; it does not establish the effect of a finished lash product.

FGF-7 · research review

The signals behind follicle renewal.

A review of FGF-7 and its receptor explores their role in follicular epithelial-cell growth and hair cycling. Much of the evidence comes from laboratory and animal models; clinical validation remains limited.
