Plume Science Elite Lash Serum Review
Brand & Product Overview
Plume Hair & Lash Science was founded as a direct response to the documented side effects of prostaglandin lash serums. The company's founding mission — explicitly stated on their website — is to offer a prostaglandin-free, hormone-free lash growth serum that achieves results through peptide science rather than FP-receptor agonism. Plume has been in this space since 2015 with their original serum; the Elite represents their second-generation, patented formulation.
🌿 $79 / 3 mL or $150 / 6 mL = ~$25–26.33 per mL · Premium PGA-Free Tier
Plume Elite is sold through Dermstore, the Plume Science website, and select clean beauty retailers. The 3 mL (3-month supply) and 6 mL (6-month supply) options reflect lash-optimised volume — significantly less product than the 15–30 mL found in conditioning oils. The Dermstore 6mL price is $120 (vs the full $150 MSRP).
🔬 Key Finding: Two of Three Toplash Peptides Are In Plume Elite
MP-17 (Myristoyl Pentapeptide-17) — upregulates keratin synthesis directly. Found in both Plume Elite and Toplash.
BTP-1 (Biotinoyl Tripeptide-1) — activates follicle bulge stem cells to extend the anagen growth phase. Found in both Plume Elite and Toplash.
This confirms that the core growth mechanism used by Toplash is validated by Plume's independent formulation decision. The peptide science is the same — the difference is in Plume's additional proprietary peptides and Toplash's AT-3 (follicle anchoring), pricing, and evidence quality.
Q5 Peptide Complex: All Five Peptides Explained
The Q5 Peptide Complex is Plume Elite's proprietary five-peptide growth system. This is the deepest peptide stack reviewed in this series. Each peptide targets a different aspect of the hair follicle growth cycle:
Plume Elite Q5 Peptide System
- Oligopeptide-251 — Plume's patented proprietary peptide (primary differentiator)
- MP-17 (Myristoyl Pentapeptide-17) — keratin gene upregulation
- MH-16 (Myristoyl Hexapeptide-16) — follicle growth factor signalling
- MT-12 (Myristoyl Tetrapeptide-12) — follicle-targeting tetrapeptide
- BTP-1 (Biotinoyl Tripeptide-1) — bulge stem cell activation / anagen extension
Supporting actives: Castor Oil, Panthenol, Caffeine, Coleus Forskohlii Extract
📌 5 growth peptides + 2 shared with Toplash · No AT-3
Toplash Triple-Peptide System
- AT-3 (Acetyl Tetrapeptide-3) — anchors follicle to dermal papilla · reduces shedding
- BTP-1 (Biotinoyl Tripeptide-1) — bulge stem cell activation · anagen extension
- MP-17 (Myristoyl Pentapeptide-17) — keratin gene upregulation · direct synthesis
Evidence: Independent 8-week clinical trial · Digital image analysis · +52.3% length · +31.9% volume
🏆 3 targeted peptides + independent verification + AT-3 anchoring
🔬 Oligopeptide-251: Plume's Patented Differentiator
Oligopeptide-251 is the defining ingredient that makes the Plume Elite formula unique. As a patented, proprietary peptide, its exact sequence and mechanism are not fully disclosed in public literature — they are protected by the patent filing. Plume positions it as the primary hair follicle growth signal in the Q5 complex.
Brand clinical data (n=85, 12-week brand study) found +8.3% lash length and +14.1% volume attributed to the complete Q5 system — it is not possible to isolate Oligopeptide-251's individual contribution from the other four peptides in the blend.
The patent filing indicates Oligopeptide-251 interacts with growth factor receptors in the hair follicle — this is a plausible hair growth mechanism consistent with how other growth-signal peptides function, but has not been independently peer-reviewed in the published cosmetic literature.
Caffeine and Coleus Forskohlii — Supporting Actives
Caffeine is a well-studied phosphodiesterase inhibitor that reduces DHT's impact on hair follicles by elevating intracellular cAMP. It has documented hair growth supporting evidence in androgenic alopecia research. In a lash context, it may improve follicle microcirculation and reduce premature telogen entry.
Coleus Forskohlii Root Extract contains forskolin, a direct adenylyl cyclase activator that raises cAMP in follicle cells — creating a similar effect to caffeine but through a different mechanism. The combination of caffeine + Coleus creates a complementary cAMP-elevating stack, supporting the growth signal created by the peptide complex.

Safety Profile
✅ SCCS/1680/25 Compliant — Prostaglandin-Free & Hormone-Free
Plume Science Elite contains no prostaglandin analogues (no ICP, DDDE, MDN) and no hormones. It is fully compliant with EU SCCS Opinion SCCS/1680/25 (February 2026). The brand was specifically founded to create a Latisse-equivalent without prostaglandin chemistry — this is not an afterthought but the core founding principle. No iris pigmentation, periorbital fat atrophy, or eyelid hyperpigmentation risk.
The formula is vegan, cruelty-free, and free from synthetic fragrances. Users with documented Ricinus Communis (castor oil) sensitivity should patch test. The myristoylated peptides (MP-17, MH-16, MT-12) use fatty acid conjugation for membrane penetration — this is a well-tolerated delivery method with an excellent periorbital safety profile.
Caffeine at typical cosmetic concentrations (0.1–2%) is well-established as safe in eye-area products. Forskolin (Coleus Forskohlii) at topical use concentrations has a good general tolerance profile; documented sensitivities are rare.
Clinical Evidence
Evidence Classification: The clinical data below are from a brand-commissioned study. While the methodology (n=85, 12 weeks, digital photography) is more robust than a simple consumer perception survey, it is not an independently conducted trial.
Plume Science's brand clinical study (n=85, 12 weeks, using digital photography and self-assessment) measured:
- +8.3% lash length increase
- +14.1% lash volume increase
- 97% of participants reported overall efficacy at 12 weeks
The 12-week study duration is longer than most competitor brand studies (most run 4–8 weeks). However, the absolute gains (+8.3% length) appear modest compared to Toplash's independent trial result (+52.3% length at 8 weeks). This difference likely reflects the different measurement methodologies: Plume's brand study vs Toplash's independently conducted digital image analysis.
Important nuance: +8.3% is likely an underrepresentation because brand studies typically use conservatively measured digital photography under variable real-world conditions. Independent standardised digital image analysis (Toplash's method) consistently captures more of the actual change. Both studies have brand-favourable incentive structures — Plume's is brand-sponsored, Toplash's is independently conducted but commissioned.

Plume Elite has MORE total peptides (5 vs 3), but lacks AT-3 — the follicle anchoring peptide that reduces premature lash shedding. Toplash has fewer peptides but includes the specific anchoring mechanism that prevents the follicle from prematurely entering telogen. The tradeoff is: Plume adds growth signal diversity; Toplash adds retention of existing lash length through AT-3.

Who Should Choose Plume Science Elite?
Plume Elite is the best choice for consumers who: (1) specifically want the broadest peptide coverage from a PGA-free serum; (2) value the additional Caffeine + Coleus Forskohlii cAMP mechanism alongside peptides; (3) appreciate a patented, proprietary formula from a brand founded on the PGA-free mission; or (4) are already on a "serum maximalist" protocol and want the most peptide diversity possible.
When Toplash Is the Right Choice
Toplash delivers independently verified results (+52.3% lash length) at $16.63/mL — roughly $8–9 less per millilitre than Plume Elite. The AT-3 anchoring mechanism (absent from Plume) reduces premature lash shedding — an important part of building length that Plume's broader peptide spectrum doesn't explicitly address. For the best combination of independently verified efficacy, complete three-point follicle coverage (anchor + activate + synthesise), and cost efficiency, Toplash leads.
Frequently Asked Questions
Does Plume Science lash serum contain prostaglandins?
No. Plume Science Elite is completely prostaglandin-free and hormone-free. It was founded specifically as a prostaglandin-free alternative to Latisse. It contains no ICP, DDDE, MDN, or any FP-receptor agonist. It is compliant with SCCS/1680/25 (February 2026) and carries no risk of iris darkening, periorbital fat atrophy, or eyelid hyperpigmentation.
What is the Q5 Peptide Complex in Plume Science Elite?
Q5 is Plume's five-peptide proprietary growth system: (1) Oligopeptide-251 — Plume's patented proprietary peptide; (2) Myristoyl Pentapeptide-17 (MP-17) — keratin gene upregulation; (3) Myristoyl Hexapeptide-16 (MH-16) — follicle growth signalling; (4) Myristoyl Tetrapeptide-12 (MT-12) — follicle-targeting; (5) Biotinoyl Tripeptide-1 (BTP-1) — bulge stem cell activation. MP-17 and BTP-1 are the same growth peptides in Toplash's triple system.
What is Oligopeptide-251 in Plume Science Elite?
Oligopeptide-251 is Plume's patented proprietary peptide — the key differentiator of their Elite formula. Its exact mechanism is patent-protected and not fully disclosed in public literature. Plume positions it as the primary hair follicle growth signal in the Q5 complex. Brand clinical data (n=85, 12 weeks) attributes the formula's +8.3% lash length and +14.1% volume to the complete Q5 system — isolating Oligopeptide-251's individual contribution is not possible from available data.
How much does Plume Science Elite cost?
Plume Science Elite retails at $79 for 3 mL (3-month supply) and $150 for 6 mL (6-month supply), equating to approximately $25–26.33/mL. Dermstore offers the 6mL at $120. This is roughly 50% more expensive per millilitre than Toplash ($16.63/mL), making it one of the most expensive PGA-free serums at retail that is not MLM-distributed.
Does Plume Science Elite share peptides with Toplash?
Yes — Plume Elite contains MP-17 (Myristoyl Pentapeptide-17) and BTP-1 (Biotinoyl Tripeptide-1), which are also in Toplash's triple-peptide system. Plume additionally includes its proprietary Oligopeptide-251, plus MH-16 and MT-12. Toplash includes AT-3 (Acetyl Tetrapeptide-3) — the follicle anchoring peptide — which is not present in Plume Elite.
How does Plume Science Elite clinical evidence compare to Toplash?
Plume's brand study (n=85, 12 weeks, digital photography): +8.3% lash length, +14.1% volume, 97% efficacy. This is brand-commissioned. Toplash's independent clinical trial (8 weeks, digital image analysis by independent lab): +52.3% lash length, +31.9% volume. The methods differ (brand vs independent, different participants, different measurement protocols) making direct numerical comparison imperfect — but the independence of Toplash's evidence is a meaningful differentiator.
Are there side effects from Plume Science Elite lash serum?
Side effects are minimal due to the PGA-free, hormone-free formula. No risk of iris colour change, periorbital fat atrophy, or eyelid pigmentation. The myristoylated peptides (MP-17, MH-16, MT-12) have an excellent periorbital tolerance profile. Users with Ricinus Communis (castor oil) allergy should patch test. Caffeine and Coleus Forskohlii at cosmetic concentrations are generally well-tolerated.
