LiLash vs GrandeLASH-MD: Which Eyelash Serum Is Better?

Between the two, LiLash has the longer track record — over 19 years on the market, vegan and cruelty-free certified, and ophthalmologist-tested. GrandeLASH-MD at ~$32.50/mL is cheaper than LiLash at ~$45/mL. Critically, both contain prostaglandin analogues in the ICP (isopropyl cloprostenate) class, covered by EU SCCS/1680/25 (February 2026) ruling ICP cannot be considered safe for cosmetic lash use, and by Health Canada's 2019 ban. Neither has independent clinical trial data. Toplash at $16.63/mL is PGA-free and independently proven with +52.3% lash length in 8 weeks — the strongest choice in this comparison.

Yes. LiLash Purified Eyelash Serum contains isopropyl phenylhydroxypentene dihydroxycyclopentylheptanate — a prostaglandin analogue that Canadian cosmetic regulations list alongside isopropyl cloprostenate (ICP) as the same compound under alternative INCI nomenclature. This means LiLash's active is subject to the same regulatory findings as GrandeLASH's ICP: EU SCCS/1680/25 (February 2026) ruling ICP "cannot be considered safe" for cosmetic lash and brow use, and Health Canada's 2019 ban on ICP in cosmetics. Using a longer chemical name on the label does not change the compound's regulatory status.

Yes. GrandeLASH-MD contains isopropyl cloprostenate (ICP), a prostaglandin analogue. Health Canada banned ICP from cosmetics in 2019. The EU SCCS issued opinion SCCS/1680/25 in February 2026, ruling ICP "cannot be considered safe" for cosmetic use in lash and brow products. ICP works by extending the anagen (growth) phase of the eyelash cycle via prostaglandin F2α receptor agonism — the same mechanism responsible for documented side effects including iris darkening, periorbital fat atrophy, and rebound shedding.

Yes, in effect. LiLash uses the INCI chemical name isopropyl phenylhydroxypentene dihydroxycyclopentylheptanate while GrandeLASH-MD uses the common trade name isopropyl cloprostenate (ICP). Canadian cosmetic ingredient regulations list both names together as the same compound. Both are synthetic prostaglandin F2α receptor agonists with the same mechanism of action, same risk profile, and the same regulatory status. The key difference is transparency: LiLash's long INCI name is less recognisable to consumers than GrandeLASH's more direct "isopropyl cloprostenate" label.

GrandeLASH-MD is cheaper per mL. At approximately $65 for 2 mL (~$32.50/mL), it costs considerably less than LiLash at $90 for 2 mL (~$45/mL). However, Toplash at $49.90 for 3 mL ($16.63/mL) is cheaper than both, is PGA-free, and is the only option in this comparison with an independent clinical trial verifying +52.3% lash length in 8 weeks. Paying a premium for LiLash's luxury branding does not add clinical substantiation or address the prostaglandin safety question.

LiLash has not been subject to a product-specific recall, but its active ingredient is confirmed identical to ICP by Canadian regulatory databases. Health Canada banned ICP (and its synonyms including isopropyl phenylhydroxypentene dihydroxycyclopentylheptanate) from cosmetics in 2019 — both names are prohibited. EU SCCS/1680/25 (February 2026) ruled ICP "cannot be considered safe" for cosmetic lash use. These findings apply to the compound regardless of which INCI name appears on the label. LiLash's 19-year market presence predates both rulings, which accounts for its continued availability in some markets.

Yes. Toplash Lash & Brow Serum is completely prostaglandin-free — no ICP, no isopropyl phenylhydroxypentene dihydroxycyclopentylheptanate, no DDDE, no MDN, no bimatoprost of any kind. Its triple-peptide complex (Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, and Acetyl Tetrapeptide-3) stimulates the lash follicle through a completely different mechanism: peptide signal pathway activation that encourages follicle cell proliferation and keratin production without prostaglandin receptor involvement. Results: +52.3% lash length and +31.9% volume in 8 weeks, verified in an independent third-party clinical trial. At $49.90 for 3 mL ($16.63/mL), Toplash is 63% cheaper than LiLash and 49% cheaper than GrandeLASH per mL — with better evidence and zero prostaglandin risk.
