Best lash serum: what 6,150 reviews say

A lash serum is a liquid you paint along the lash line, and the usual goal is longer, fuller-looking lashes without sore eyes. We read 6,150 Ulta and Sephora reviews of three popular picks to see how often reviewers reported that result, and how often they reported eye irritation, darkened lids, discoloration or eye-color change, or no change: the Babe Original Essential Lash Serum, the Grande Cosmetics GrandeLASH-MD Lash Enhancing Serum and the e.l.f. Enhancing Lash & Brow Serum. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF] [A1] [A2] [A3]

GrandeLASH-MD drew longer-or-fuller reports from 55% of 4,456 usable reviews and eye-irritation reports from 24%; 21% gave one or two stars. Babe drew longer-or-fuller reports from 36% of 294 and eye-irritation reports from 8%; 8% gave one or two stars. e.l.f. drew longer-or-fuller reports from 29% of 153 and eye-irritation reports from 11%; 19% gave one or two stars. Star shares come from different sites and years, so read them as context. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF]

Which reviews we read, and the 1,247 we set aside

Ulta's pages did not serve every review. They served 300 of 9,058 shown for Babe, 270 of 3,211 for GrandeLASH-MD and 295 of 4,832 for e.l.f., newest first. On Sephora we read all 5,285 US English GrandeLASH-MD reviews in the feed, from 2017 to 2026, after skipping 634 marked incentivized and 40 by staff without reading them; that page shares reviews across the regular, mini and jumbo sizes. We kept 4,903 and set aside 1,247. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF]

Most of what we set aside came in waves. On Sephora, GrandeLASH-MD drew 406 reviews in March and April 2018 and 504 from March to June 2022, several times its usual monthly count. 160 of the 280 Sephora reviews that said the product was free fell in those months, and among the reviews in those months that did not say free, the one- and two-star shares were 11% and 9%, against 20% for the Sephora reviews we kept. On Ulta, e.l.f. drew 134 reviews in December 2024 and January 2025, the first two months its pages served; 7 of its 13 free reviews fell there, and 6% of the rest gave one or two stars against 19% for the e.l.f. reviews we kept. We also set aside the 10 GrandeLASH-MD Ulta reviews from May 2026, 6 of which said free. Babe's busiest months, December 2025 and January 2026 (135 reviews), we kept: none of Babe's reviews said free, and their 4% one- and two-star share (5 of 135) was close to the 6% (5 of 90) of the months before. [R-SEP-GRA] [R-ULT-ELF] [R-ULT-GRA] [R-ULT-BAB]

Beyond those waves we set aside 143 more reviews that said the product was free, 9 repeated on the same page and 41 about another product, shipping, not yet used, not in English or with no text. Some cautions: GrandeLASH-MD makes up 4,456 of the 4,903 usable reviews, and 2,319 of them are from 2017 to 2020. Babe and e.l.f. are Ulta only and recent, and e.l.f. has 153 usable reviews, a smaller base. 34% of Babe's reviews were general praise or complaints with no specific claim.

Babe lash serum reviews turned less kind lately

Babe's listing describes its serum as a lash enhancing treatment for fuller and longer looking lashes that can be used on lashes, brows and with lash extensions. It says to apply a thin line to the clean, dry lash line above the skin, dip the wand once for both lids and let it dry for 1 to 2 minutes. We link the 1 mL Starter Supply sold by Babe Original and shipped by Amazon. [A1]

Across 294 usable Ulta reviews, 106 (36%) said lashes looked longer or fuller, 50 (17%) said they would buy it again and 29 (10%) said it was gentle for them. 24 (8%) reported eye irritation, 3 darkened lids, discoloration or eye-color change and 6 no visible change. [R-ULT-BAB]

Babe original lash serum reviews changed over the year we could read. Of 219 usable reviews through January 2026, 7 (3%) reported eye irritation and 4% gave one or two stars. Of the newest 75, from February 2026 on, 17 (23%) reported eye irritation and 19% gave one or two stars. We cannot tell the cause from the reviews. [R-ULT-BAB]

Grande lash serum: the most growth reports, and the most eye irritation

Grande's listing describes GrandeLASH-MD as a peptide and vitamin infused, ophthalmologist tested serum. It says to apply it once daily to a clean, dry upper lash line only, like a liquid eyeliner, let it dry for 2 to 3 minutes, keep it out of the eyes and rinse with cool water on direct contact, and it claims results in as little as 4 to 6 weeks with full improvement in 3 months. We link the serum shipped and sold by Amazon.com; the page showed a 4 ml option while the title mentions a 1mL, 6 week supply and a bullet says 6-month supply. [A2]

Of 4,456 usable reviews (4,217 Sephora, 239 Ulta), 2,461 (55%) said lashes looked longer or fuller, 1,274 (29%) gave a time for that result and 839 (19%) said they would buy it again. 1,081 (24%) reported eye irritation, 421 (9%) darkened eyelid skin, under-eye discoloration or an eye-color change, and 204 (5%) said lashes shed more or grew in crooked or tangled. 40 reported fat loss or a hollow or sunken look around the eyes. [R-ULT-GRA] [R-SEP-GRA]

Ulta and Sephora read differently at first glance: 41% of 239 Ulta reviews reported longer or fuller lashes against 56% of Sephora's, and 27% against 24% reported eye irritation. Much of the growth gap lines up with time. Ulta's reviews run from 2025 to 2026, and Sephora's 619 reviews from 2024 on came to 43% longer or fuller, close to Ulta's 41%, and 34% eye irritation, higher than Ulta's 27%. Its 2,319 reviews from 2017 to 2020 came to 60% and 21%. [R-ULT-GRA] [R-SEP-GRA]

e.l.f. Enhancing Lash & Brow Serum, the easy lash and brow pick

e.l.f.'s listing describes a clear conditioning serum with antioxidants, amino acids and vitamins for longer-looking lashes and fuller-looking brows, to apply to the upper and bottom lash line and/or brow hairs morning and night. Its Amazon listing prints an ingredient list, including glycerin, sodium hyaluronate, castor seed oil and ginseng root extract. We link the 0.12 fl oz (3.5 mL) serum shipped and sold by Amazon.com. [A3]

Of 153 usable Ulta reviews, 33 (22%) called it easy to apply, 24 (16%) used it on brows and liked the result and 26 (17%) said it was gentle for them. 44 (29%) said lashes looked longer or fuller, the lowest of the three, and 25 (16%) saw no visible change. 17 (11%) reported eye irritation, close to Babe's 8%. With 153 reviews, a few can move these shares. [R-ULT-ELF]

How each lash serum feels on the eyes, per reviewers

Gentle-for-me praise was modest for all three: 17% for e.l.f., 10% for Babe and 7% for GrandeLASH-MD. Eye irritation, meaning burning, itching, red or watery eyes, swollen or irritated lids, was reported by 24% of GrandeLASH-MD reviews, 11% of e.l.f. and 8% of Babe. On application, 22% of e.l.f. reviews called it easy to apply, against 4% for Babe and 2% for GrandeLASH-MD. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF]

Sensitive eyes or contacts: 36 of 105 GrandeLASH-MD reviewers who said so reported eye irritation, while 60 called it gentle for them. Babe (5) and e.l.f. (4) had too few such reviewers to compare. Lash extensions: of 445 GrandeLASH-MD reviewers who mentioned extensions or a lash lift, 335 said lashes looked longer or fuller and 56 reported eye irritation. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF]

Whichever serum you pick, follow the listing directions; Grande's says to keep it out of the eyes and rinse with cool water on direct contact. Stop if your eyes or lids get irritated. If you want to avoid a specific ingredient, read the full list on the package; the Babe and GrandeLASH-MD Amazon listings we checked do not print one. [A1] [A2] [A3]

Lash serum growth reports in older and newer reviews

If you are after the best lash growth serum by reviewer reports, look at those who stayed with it. For lash serum growth, they reported more: 773 of 1,071 GrandeLASH-MD reviewers who said they used it for at least 8 weeks reported longer or fuller lashes, as did 26 of 54 for Babe and 6 of 15 for e.l.f. The e.l.f. group is small, and this is a self-selected group: people who stopped early rarely say how long they tried. [R-ULT-BAB] [R-ULT-GRA] [R-SEP-GRA] [R-ULT-ELF]

GrandeLASH-MD's reviews shifted over the years: longer-or-fuller reports went from 60% of 2,319 reviews from 2017 to 2020, to 56% of 1,279 from 2021 to 2023 and 42% of 858 from 2024 on, while eye-irritation reports went from 21% to 25% and 32%. In the 2024-on window it still drew more growth reports than Babe (36%) and e.l.f. (29%), by a narrower margin. [R-ULT-GRA] [R-SEP-GRA] [R-ULT-BAB] [R-ULT-ELF]
