The science behind the growth

A botanical-rich formula built on two clinically studied peptides — designed to nourish at the root and support the natural growth cycle, with none of the prostaglandins that cause irritation and discoloration.

Biotinoyl Tripeptide-1

A patented peptide clinically shown to strengthen and stimulate lash & brow growth at the follicle level.

Acetyl Tetrapeptide-3

Targets the dermal papilla to extend the anagen (growth) phase of the natural hair cycle for fuller-looking lashes.

Doe-foot precision applicator

A soft, tapered tip lays a fine line of serum exactly along the lash line — no waste, no mess, no flooding the eye.

Real Results

60 days of growth

Drag the slider to see the difference. With nightly use, Maddi went from a bare lash line to three full layers, corner to corner — no redness, no irritation.

Results vary. Use continually for best results.

"I'd tried every serum on the market — including prescription-strength formulas. They worked, but the side effects were brutal. After switching to this, I went from a completely bare lash line to three full layers in about 60 days. No redness. No irritation."

Questions, answered

Can I use it with lash extensions?

Yes — it's safe with all types of lash extensions. Apply along the natural lash line nightly as usual.

Does it contain prostaglandins?

No. The formula is completely free of prostaglandin analogues — the hormones found in prescription lash serums that can cause discoloration, redness, and other side effects.

When will I see results?

Most customers notice a difference within 4–6 weeks of nightly use, with full results visible by 60 days. Consistency is key — results improve with continued use.

Can I use it on my brows?

Absolutely. The same peptide technology that supports lash growth works just as well on brows. Apply a thin line along sparse areas each night.
