Direct answer
Compare 13 exact lash serums by disclosed ingredients, documented evidence and dated US price per mL, with Plume ownership and each record’s limitations visible.
This manufacturer-published comparison covers 13 exact products in the US market. Eight disclosed lists contain no screened analogue name; four list an analogue, including prescription LATISSE; NutraLuxe has an unresolved current full ingredient record. This is ingredient screening, not a safety certification.
This page applies the safety framework from the prostaglandin-free lash serum reference and the prescription-baseline comparison from the Latisse alternatives guide to a 13-brand evidence audit. Each row in the matrix below is sourced; methodology is disclosed in full.
Publisher disclosure
This article is published by Plume Science. Plume Elite is one of the 13 products audited. The methodology and evidence axes below describe how every product was evaluated, including our own. Affiliate or commercial relationships, where present, are disclosed at the product level.
The 30-second shortlist
Three prostaglandin-free options for three priorities
Plume publishes this comparison and sells Plume Elite. Our premium pick is based on the audit's disclosed documentation criteria. Plume's finished-product study was company-sponsored, observational, not peer reviewed, and not a head-to-head trial.

13 exact products; one US market record per named formula.
Price, size and sources are dated. One-time prices exclude subscriptions.
Study designs differ; no universal efficacy ranking is calculated.
Unknown and conflicting records remain visible in every export.
How We Compared
We checked official product pages, their product variant records, disclosed ingredient lists, public study records and patent documents. Full field-level provenance appears within each matrix row. Product names sort alphabetically. Plume publishes the comparison and sells Elite.
Ingredient-level research, a granted patent, editorial coverage, retailer listings and customer reviews have different purposes; they are not interchangeable with finished-product evidence. No screened ingredient name found is a limited label observation. Different markets and reformulations remain separate. Missing data does not mean zero efficacy or safety.
Plume's documentation-focused choice: Elite. Choose it if you value a complete ingredient list, one lash-and-brow formula, a public company-sponsored observational study and a granted composition-patent record. These records make the evidence inspectable; they do not establish superiority.
Lower initial price: The Ordinary 5 mL is US$14.90 (US$2.98/mL); SOWN Root 1 3 mL is US$58 (US$19.33/mL), compared with Elite 6 mL at US$150 (US$25.00/mL). Product scope and directions differ. Checked October 2, 2026.

Mechanism Explainers
Prescription bimatoprost and cosmetic analogue context
LATISSE contains prescription bimatoprost 0.03%, while GrandeLASH-MD and Babe Original Essential list isopropyl cloprostenate and RevitaLash Advanced lists DDDE. These are not interchangeable finished products. Prescription bimatoprost has its own FDA label and clinical evidence; the cosmetic analogues were evaluated separately by the EU SCCS, which concluded that IPCP, DDDE, and MDN could not be considered safe for cosmetic use at the proposed concentrations in Opinion SCCS/1680/25. Periorbital changes associated with ophthalmic prostaglandin analogues are described in the clinical literature. NutraLuxe Lash MD remains unverified because the last located public INCI, from December 2020, listed MDN but a current full formula was not available.
Peptide-stack mechanism
The Ordinary Multi-Peptide Lash and Brow Serum, SOWN Root 1, Babe Original Renewing, and GrandeLASH-Sensitive disclose cosmetic peptides such as Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, or Acetyl Tetrapeptide-3. Ingredient-list presence alone does not establish a shared mechanism, concentration, or clinical effect, and this audit did not identify product-specific peer-reviewed clinical mechanism studies for those peptide stacks. Kang et al. 2022 (PMID 36012223) was an in-vitro alpha-phellandrene study in human dermal papilla cells that used forskolin as a positive control; it did not study these cosmetic peptides or any finished lash serum. GrandeLASH-Sensitive and Babe Original Renewing have substantially overlapping public INCIs, but that overlap does not establish identical formulas, suppliers, concentrations, or performance.
Phyto and botanical-only mechanism
Lashfood Phyto-Medic uses Paeonia, Panax Ginseng, Portulaca Oleracea, and Prunus Mume in a 22-ingredient list with no peptides. Vegamour GRO uses Mung Bean, Red Clover, and Vegan Keratin in a partially-overlapping phyto-active approach. Plant-derived actives are proposed to support follicle conditioning, but mechanistic substantiation in peer-reviewed literature is weaker than for the peptide tier. Lashfood is certified ECOCERT at 99.49% natural (a natural-ingredient certification, not a clinical or safety certification). Vegamour is Leaping Bunny and vegan-certified.
Oil and adaptogen-botanical mechanism
Luna Nectar Moon Boost uses Castor Oil, Argan Oil, and Sweet Almond Oil as carriers with traditional Chinese medicine adaptogens (Centella Asiatica, Burdock, Horsetail, Bamboo) in a 20-ingredient list with zero synthetic peptides. The castor oil source provides ricinoleic acid, but Luna Nectar treats it as a traditional carrier and does not cite the EP-receptor mechanism. Brand certifications include Leaping Bunny, Vegan, and Organic.
Plume Elite multi-mechanism
Plume Elite is a prostaglandin-free cosmetic lash and brow serum with five disclosed peptides and the patented C2 Complex. Forskolin is a laboratory adenylyl-cyclase activator (Hedin & Rosberg, Mol Cell Endocrinol 1983, PMID 6315510), while ricinoleic acid has shown EP3/EP4 activity in non-eyelash experimental systems (Tunaru et al., PNAS 2012, PMID 22615395). These studies provide ingredient-level mechanistic context only. They do not establish finished-product lash-growth efficacy, equivalence to bimatoprost, or pregnancy safety. Kang et al. 2022 (PMID 36012223) studied alpha-phellandrene in vitro and used forskolin as a positive control; it was not a Plume or peptide study.
Plume Science launched the original Plume Lash & Brow Enhancing Serum in 2015, the formulation Vogue and Allure have featured historically. Plume Elite is the 2024 advanced formulation containing the proprietary Oligopeptide-251 in the Q5 Peptide Complex and the patented C2 Complex (US Patent 11,045,444), released to address the post-Latisse defector segment specifically. The public 8-week prospective observational study with 85 completers is tied to the Elite SKU. A December 2025 NewBeauty article provides editorial coverage about Elite but is not counted as clinical evidence. Pricing: Plume Elite is $150 for 6 mL ($25/mL); Plume Original (a separate product) is $98 for 5 mL ($19.60/mL).
Plume Elite combines a disclosed five-peptide system with forskolin and ricinoleic acid. The cited studies on forskolin and ricinoleic acid are ingredient-level laboratory or non-eyelash experimental evidence, not clinical evidence for the finished serum. The public Plume Elite study is company-sponsored and observational; it was not peer reviewed, randomized, or compared head-to-head with LATISSE. NewBeauty's December 2025 article provides publication coverage only, not independent clinical validation or evidence of sensitive-eye suitability.

Every claim about Plume Elite on this page is sourced. The matrix below summarizes the canonical evidence cited inline.
Plume Elite evidence inventory
Evidence axis
Plume Elite
Clinical study
Company-sponsored 8-week prospective observational study with 85 completers. Read the public study summary or Zenodo record. It was not peer reviewed, randomized, or head-to-head. A separate prior-LATISSE subset summary (Zenodo record) is descriptive tolerability evidence, not comparative efficacy evidence.
Patent
C2 Complex covered under US Patent 11,045,444 (forskolin and ricinoleic acid composition).
Q5 Peptide Complex
Five disclosed peptides: Oligopeptide-251, Myristoyl Pentapeptide-17, Myristoyl Hexapeptide-16, Myristoyl Tetrapeptide-12, and Biotinoyl Tripeptide-1. This inventory does not rely on comparative peptide-count language from editorial coverage.
Mechanism
Ingredient-level context only: forskolin is a laboratory adenylyl-cyclase activator (Hedin & Rosberg, 1983; PMID 6315510), and ricinoleic acid has EP3/EP4 activity in non-eyelash experimental systems (Tunaru et al., 2012; PMID 22615395). These sources do not establish finished-product efficacy, equivalence to bimatoprost, or pregnancy safety. Kang et al. 2022 (PMID 36012223) studied alpha-phellandrene in vitro, not Plume Elite or cosmetic peptides.
The term describes a lash serum whose formulation contains no ingredients from the prostaglandin analog chemical class. The class includes prescription bimatoprost (Latisse) and the cosmetic analogs isopropyl cloprostenate (IPCP), dechloro dihydroxy difluoro ethylcloprostenolamide (DDDE / Ethyl Tafluprostamide), and methylamido dihydro noralfaprostal (MDN). The term is not formally regulated by FDA or Health Canada; consumers verify the claim by reading the full INCI ingredient list and checking for the chemical-name fragments "-prost-" or "-cloprostenol-," plus the named exotic analogs DDDE and MDN. The EU SCCS concluded in February 2026 that IPCP, DDDE, and MDN could not be considered safe for cosmetic use at the proposed concentrations (Opinion SCCS/1680/25). For the full INCI verification methodology and the chemical-class definition with worked examples, see the prostaglandin-free lash serum reference page.
What is documented versus what is not. Plume's 8-week study is publicly available through the study summary and Zenodo record. It was company-sponsored, observational, not peer reviewed, not randomized, and not a head-to-head comparison with LATISSE; self-reported outcomes and the study design limit causal and comparative conclusions. The separate prior-LATISSE subset summary (Zenodo record) is descriptive tolerability evidence only. Long-term finished-product safety beyond the study period has not been established. NutraLuxe Lash MD remains unverified because a current full INCI was not publicly available. Much of the category's cosmetic product evidence is manufacturer-issued rather than independent.
Some finished products report cosmetic improvement, but formulations and study quality vary. Direct randomized comparisons with bimatoprost are generally unavailable, so ingredient mechanisms should not be treated as proof of equivalent efficacy.
Why avoid prostaglandins?
Prescription bimatoprost and cosmetic prostaglandin or prostamide analogues should not be assumed to have identical mechanisms, potency, or clinical effects. The current LATISSE label describes product-specific risks, and the EU SCCS concluded that IPCP, DDDE, and MDN could not be considered safe for cosmetic use at the proposed concentrations in Opinion SCCS/1680/25. Read the current label and full INCI for the product you are considering.
Which popular brands are prostaglandin-free?
Eight disclosed lists have no screened analogue name: Elite, GRO, The Ordinary, Root 1, LASHFOOD, Moon Boost, GrandeLASH-Sensitive and Babe Renewing. This October 2, 2026 US label screen is limited to the named products and ingredients; it is not a universal safety certificate.
How long do prostaglandin-free lash serums take to work?
Timelines and application schedules vary by finished product. Follow the current directions and assess the named product's study design rather than applying a category-wide onset claim. In Plume's company-sponsored 8-week prospective observational record for Elite, most of the 85 completers reported noticeable results within 3 weeks. The record was not randomized, peer reviewed, or head-to-head, and individual response varies.
What's the difference between Plume Original and Plume Elite?
Original and Elite are separate formulas and products. The eight-week observational study with 85 completers belongs to Elite. Elite is offered in 3 mL and 6 mL sizes. Use each current product page for its ingredients, price and supporting evidence.
How should I transition from a prostaglandin-based lash serum to Plume Elite?
Do not change or stop prescribed bimatoprost without your prescriber. The current LATISSE label says eyelashes are expected to return toward their pre-treatment level after discontinuation. Plume has no randomized evidence that tapering prevents shedding; ask your prescriber about timing before changing products.
Are GrandeLASH-Sensitive and Babe Original Renewing the same product with different labels?
They are separate products with separate official ingredient records. Some listed ingredients overlap, but that does not establish identical formulas, concentrations, manufacturing or performance. Compare the full lists, directions and evidence for each exact product in the matrix.
Is medical-grade a regulated term?
No. Neither the FDA nor Health Canada formally regulates medical-grade as a cosmetic category. Plume uses the term as a positioning descriptor, not as an FDA or Health Canada endorsement and not as proof of drug-level efficacy or safety. Compare the underlying formula, study design, limitations, and distribution rather than relying on the term alone.
Is RevitaLash Advanced prostaglandin-free?
The current US Revitasome formula lists ethylcloprostenolamide, identified by the manufacturer as a prostaglandin analogue. This record was checked October 2, 2026. Older DDDE ingredient lists, other markets, Advanced Pro and Sensitive must not be treated as the same formula.
Is Vegamour really prostaglandin-free?
The current US GRO Lash Serum ingredient list contains no screened analogue name in this comparison. The disclosed formula includes botanical extracts and acetyl tetrapeptide-3. Verify your package and market; ingredient screening does not establish safety or comparative effectiveness.
Can I use a prostaglandin-free lash serum during pregnancy?
“Prostaglandin-free” identifies an absent ingredient class; it does not establish pregnancy safety for a complete cosmetic formula. Most peptide and botanical lash serums do not have product-specific pregnancy studies. Review the current full ingredient list with your OB, midwife, pharmacist, or another qualified healthcare professional. See Plume's lash-serum pregnancy evidence guide.
Will my lashes return to baseline if I stop a prostaglandin-free serum?
Results from cosmetic serum use may require continued use, but the course after stopping varies by product and person. This audit did not identify evidence supporting a universal 8-to-12-week return-to-baseline timeline or a guarantee of no shedding.
Why does Plume name Elite its premium documentation pick?
Plume names Elite its premium documentation pick based on a public company-sponsored 8-week observational study with 85 completers, a granted formula patent, formula documentation, and full ingredient disclosure. The study is publicly archived but was not peer reviewed, randomized, or head-to-head, and it does not establish equivalence to LATISSE. NewBeauty is listed separately as editorial coverage and is not counted as clinical evidence or proof of sensitive-eye suitability.
Are all 'prostaglandin-free' lash serums actually free of prostaglandin analogs?
Marketing names alone do not establish a formula's contents. This comparison distinguishes disclosed analogue ingredients, no screened name found, and unresolved full ingredient records. Check the exact product, current package and market; do not infer safety from a missing dictionary match.
How to Verify Any Future Brand Against This Framework
The 12-axis framework is the page's claim to category authority, not the specific 13 brands. To evaluate a future product not in this matrix, capture the brand's current INCI from its product page, identify the named active complex, check for chemical-name fragments "-prost-" or "-cloprostenol-" plus the named exotic analogs DDDE and MDN, locate any clinical study (n, design, supervision), check the US Patent Office for a granted composition or method patent, cross-reference regulatory state at FDA, Health Canada Cosmetic Ingredient Hotlist, EU SCCS Opinions, ANSES VigilAnses, and UK MHRA, and look up named third-party editorial in NewBeauty, Allure, Vogue, Glamour, or peer-reviewed dermatology / ophthalmology journals.
