What reading every label actually showedWe pulled the complete INCI list for all six serums directly from each brand’s own product page on 8 September 2026. Five of the six contain a prostaglandin analog. Only The Ordinary’s Multi-Peptide Lash and Brow Serum does not — which is why we raised its score after the check. That includes our own top pick: Qualash contains Ethyl Tafluprostamide. If a brand’s marketing feels clean and botanical, that tells you nothing; only the ingredient list does.

Editor's Choice 2026

QUALASH® Advanced Eyelash Growth Serum

Qualash · 3.5 ml (0.12 fl oz) · ~3 months

Every serum in this ranking except one contains a prostaglandin analog, so the real question is not whether a formula uses one but how honestly it is built around it. Qualash is the best answer we found. Its two lead ingredients are Myristoyl Pentapeptide-17 and Myristoyl Hexapeptide-16 — they sit second and third in the INCI list, ahead of everything else — with arginine and a soy, wheat-germ and Scutellaria baicalensis complex behind them. The prostaglandin, Ethyl Tafluprostamide, appears low in the list, below the preservative system. Compare that with GrandeLASH-MD or Babe Lash, where the analog is the formula’s reason for existing and the rest is amino acids and humectants. Qualash also publishes the complete INCI list on its own product page, states a dated 25-day first-change window instead of a seven-day fantasy, ships the most controlled applicator in the group, and guarantees a full 90 days — long enough to actually finish a treatment cycle before deciding.

What we liked

Peptides lead the INCI list; the prostaglandin sits low, below the preservatives
Publishes the complete INCI on its own product page — most rivals publish a curated summary
Realistic, dated claims (25 days first change, 12-week full cycle)

Strongest raw growth

GrandeLASH-MD Lash Enhancing Serum

Grande Cosmetics · 2 ml (~3 mo) or 4 ml (~6 mo)

The most recognised name in US lash serums, and for raw millimetres it earns that. The active is isopropyl cloprostenate, which Grande labels in plain language as “an analog of prostaglandin” — a level of candour worth crediting. Around it sits a long amino-acid, humectant and botanical list that softens the drying effect but does not change the mechanism. Prostaglandin analogs are associated in the dermatology and ophthalmology literature with conjunctival redness, periorbital skin darkening and, in a minority of long-term users, iris pigmentation change and orbital fat atrophy. One thing our INCI comparison turned up: Grande’s ingredient list and Babe Lash’s are near-identical in composition and order, which points to a shared formulation base.

What we liked

Fastest visible length of anything in this ranking
Names the prostaglandin analog on the label in plain language
Excellent availability and a well-run returns process

What to weigh

Verdict: Choose it if maximum speed matters most and you accept the trade-off knowingly — but read our side-effects guide first, and note that Babe Lash offers a near-identical formula.

Best-built supporting formula

RevitaLash Advanced Eyelash Conditioner

RevitaLash Cosmetics · 2.0 ml (~3 mo) or 3.5 ml (~6 mo)

Two decades of iteration show in the supporting cast: biotin, biotinoyl tripeptide-1, octapeptide-2, ginseng, saw palmetto, green tea and Swertia japonica make this the most thoroughly built conditioning base in the ranking, and lashes finish noticeably glossier than average. The active is ethylcloprostenolamide, which RevitaLash labels openly as “a prostaglandin analogue”. Note this is not the same molecule as the longer dechloro dihydroxy difluoro ethylcloprostenolamide that appears on some competitor labels — but it is the same family, with the same cautions. The barrier here is price: at $152 for the 3.5 ml, it is the most expensive way to run a year in this ranking.

Contains ethylcloprostenolamideAnalogue named on the labelStrongest conditioning basePremium price

What we liked

The most complete supporting formula of anything we checked — peptides, biotin and five botanical actives
Names the prostaglandin analogue explicitly on the label
Visibly glossier, less brittle lashes than any rival

Verdict: The best-formulated conditioning base in the group, wrapped around the same class of active as everything else — and priced accordingly.

UKLASH eyelash growth serum, black 3 ml bottle with fine liner applicator

Has a genuine PG-free sibling

UKLASH Eyelash Serum

UKLASH · 3 ml (0.10 fl oz) · ~3 months

The flagship UKLASH serum contains isopropyl cloprostenate — the same active as GrandeLASH-MD and Babe Lash — described on the brand’s own page as a “low & safe level of the most potent and well-researched active ingredient”. That phrasing is doing some work, but the disclosure is there. What earns UKLASH its place is what sits alongside it: biotinoyl tripeptide-1 and Myristoyl Pentapeptide-17 are genuine peptides rather than filler, and the botanical list (centella, liquorice root, rosemary, Japanese knotweed, Scutellaria) is better than the amino-acid soup in the Grande/Babe base. Importantly, UKLASH also sells a Complex Peptide Lash Serum and a Sensitive Lash Serum that genuinely omit the analog — if you want prostaglandin-free from this brand, those are the products, not this one.

Contains isopropyl cloprostenateReal peptides in the basePG-free versions available3 ml bottle is small for the price

What we liked

Peptides and botanicals that do real work, not just amino-acid filler
Brand openly sells prostaglandin-free alternatives for people who want them
Fine liner applicator with good lash-line control

What to weigh

Contains isopropyl cloprostenate despite a clean-looking brand story

Verdict: A better-built formula than its price-peers, but do not mistake it for a gentle option — for that, buy the brand's Complex Peptide or Sensitive version instead.

Same formula, lower price

Babe Original Essential Lash Serum

Babe Original · 1 ml, 2 ml or 4 ml

Put Babe Lash’s INCI list next to GrandeLASH-MD’s and the overlap is hard to miss: the same active, the same radish-root ferment preservative system, the same amino-acid block, the same ginseng and grape-seed extracts, in near-identical order. The practical consequence is simple — if you have decided that isopropyl cloprostenate is acceptable for you, this is the cheaper way to buy essentially the same thing. The applicator is the weak point: it is broader than Grande’s, which makes precise lash-line placement harder, and placement accuracy is exactly what limits lid pigmentation.

What we liked

Verdict: The value route into the isopropyl cloprostenate class — but the safety caveats do not get cheaper along with the price.

The only prostaglandin-free pick

The Ordinary Multi-Peptide Lash and Brow Serum

The Ordinary · 5 ml · ~4–5 months

We raised this product’s score after verifying every INCI list in this ranking, because it turns out to be the only one of the six with no prostaglandin analog in it at all. It runs four peptides — Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, Oligopeptide-2 and Acetyl Tetrapeptide-3 — with caffeine, panthenol and larch, red clover and green tea extracts. It will not match the length of the five serums above it, because nothing peptide-only does; expect conditioning, less breakage and a modest density gain over twelve to sixteen weeks. At $14.90 for 5 ml it is also the cheapest product here by a factor of three, and the doe-foot applicator is its real weakness at the lash line.

No prostaglandin analog — verifiedFour peptides in the base$14.90 for 5 mlConditioning, not transformativeDoe-foot applicator

What we liked

The only serum in this ranking with no prostaglandin analog on the INCI list
Four peptides, not one token peptide behind an active
Lowest cost per millilitre by a wide margin, and it doubles as a brow product

What to weigh

Noticeably smaller effect than the prostaglandin serums — this is the trade-off, not a flaw

How these scores were built

Full method

Measured change, not vibes

Every serum runs a 12-week cycle with a fixed panel. We photograph at day 0, 28, 56 and 84 under identical lighting, fixed focal length and a millimetre reference marker, then measure the longest five lashes per eye. Self-reported 'it looks better' never enters a score.

Ingredient forensics

We read the full INCI list, not the marketing page. Prostaglandin analogs, undisclosed actives, preservative systems and known ocular irritants are logged individually. A serum that hides its mechanism loses points before it is ever applied.

Tolerance tracking

Testers log irritation, dryness, redness, lid darkening and any visual change daily. Any adverse event is recorded and published, including for products we rank highly.

Cost per treated month

Price is normalised to the cost of one full 12-week cycle plus six months of maintenance, so a cheap 2 ml tube that runs dry in eight weeks does not beat a larger bottle on headline price.

Applicator and waste

Brush precision determines how much product lands on the lid rather than the lash line — which is exactly where pigmentation problems start. We score tip geometry, product load and dry-down.

Company transparency

Published ingredient lists, honest timelines, a real returns policy and a reachable human. Guarantee length is scored; a 90-day guarantee that covers a full cycle is worth more than a 30-day one that cannot.
