The science behind EYRĀ
You don't need prostaglandins
for real results.
We replaced the ingredient that scares you with a botanical complex that works with your body — not against it. Here's exactly how.
What most serums don't tell you
Prostaglandins work. But at what cost?
Most lash serums that deliver fast, visible results rely on prostaglandin analogs — synthetic compounds originally developed for glaucoma treatment. They extend the lash growth phase aggressively. The results are real. So are the side effects.
Documented risks include permanent iris color change, orbital fat loss that makes eyes look sunken and aged, eyelid hyperpigmentation, chronic redness and irritation, and unwanted facial hair growth where the serum migrates.
We decided early on: EYRĀ would never contain a single prostaglandin. Not now. Not ever.

Sunken eyes
Eyelid darkening
Chronic irritation
Unwanted hair growth
The EYRĀ approach
Three mechanisms. Zero prostaglandins.
Instead of forcing the lash cycle with synthetic hormones, we work with your body's natural processes.
Mechanism 01
Support the growth phase
Swertia Japonica and Saw Palmetto work together to support the anagen (active growth) phase of your natural lash cycle — helping each lash reach its full potential length before it naturally sheds.
Mechanism 02
Strengthen from the root
Biotinoyl Tripeptide-1 and Myristoyl Pentapeptide-17 stimulate keratin production at the follicle level. Stronger roots mean less breakage, less shedding, and lashes that stay in place longer.
Mechanism 03
Condition and protect
Panthenol, Biotin, Hyaluronate, and Vitamin E hydrate each lash strand, improve flexibility, and protect against environmental damage — so lashes look healthier, shinier, and more resilient.
Every ingredient, explained
Swertia Japonica Extract
Growth support
A botanical from traditional Asian medicine. Improves microcirculation around lash follicles, ensuring they receive nutrients and oxygen for optimal growth. Helps support a healthy lash cycle and reduces premature shedding.
Biotinoyl Tripeptide-1
Follicle strength
A biotin-enriched peptide that promotes keratinocyte proliferation at the follicle and improves hair anchorage. Clinical studies show 17% increase in lash length and 19% increase in thickness after 30 days.
Myristoyl Pentapeptide-17
Keratin production
A five amino acid peptide that stimulates keratin gene expression — convincing your cells to produce more of the structural protein that gives lashes their strength, flexibility, and shine.
Panthenol (Pro-Vitamin B5)
Conditioning
Penetrates the lash fiber and converts to pantothenic acid, adding strength, shine, and softness. Improves flexibility and reduces breakage — especially important for lashes weakened by extensions or makeup.
Biotin (Vitamin B7)
Reinforcement
The well-known hair and nail supplement, applied topically. Reinforces lash structure, reduces brittleness, and supports the follicle environment for healthy lash appearance.
Sodium Hyaluronate
Hydration
Creates an optimal hydration environment around each follicle. Well-hydrated lashes are stronger, more flexible, and significantly less prone to breakage during the growth cycle.
Hydrolyzed Keratin
Structure
The same protein your lashes are naturally made of, in a form small enough to penetrate the lash fiber. Repairs damage, fills gaps in the lash structure, and restores strength from within.
Saw Palmetto Extract
Shedding prevention
Provides a natural DHT-blocking effect that helps prevent premature lash shedding. Strengthens follicles and reduces inflammation around the lash line for a healthier growth environment.
Understanding the lash cycle
Why real results take 3 months.
Your lashes don't all grow at the same time. Each one is at a different stage. A full cycle takes 8–12 weeks — and only a 3-month commitment covers every single lash.
Phase 1
Anagen
4–10 weeks · Active growth
The follicle is attached to blood supply, receiving nutrients. This is when the lash actively grows. EYRĀ's peptides and botanicals support this phase for maximum length.
Phase 2
Catagen
2–3 weeks · Transition
The lash stops growing and the follicle begins to shrink. EYRĀ's conditioning agents keep the lash strong, flexible, and anchored during this vulnerable transition.
Phase 3
Telogen
3–4 months · Rest & release
The lash rests, then naturally falls out as a new one begins growing underneath. Saw Palmetto and biotin help reduce premature shedding during this phase.
At any given time, your lashes are spread across all three phases. A single bottle covers 1 month — not enough for every lash to complete a full cycle.
The Full Cure (3 months, $99) ensures every lash gets the full benefit.
Clean by choice
What you won't find in our formula.
✗
Prostaglandins
Linked to permanent iris color change, orbital fat loss, and eyelid hyperpigmentation. We will never use them.
✗
Parabens
Preservatives linked to potential hormone disruption. We use safer alternatives to keep the formula stable.
✗
Fragrance
A common irritant near the eyes. Our serum has no added fragrance — because near your eyes, nothing unnecessary belongs.
✗
Hormones
Our formula is 100% hormone-free. Nothing that enters your bloodstream, nothing that affects your body beyond your lash line.
✗
Harsh chemicals
No sulfates, no phthalates, no synthetic dyes. Every ingredient was chosen for sensitive eyes first.
✗
Animal testing
Vegan-friendly and cruelty-free. Always. We don't test on animals and we never will.
