Also listing one, with fewer sales: Babe Original Eyebrow Serum, fLASH Eyelash Serum Mini, neuBROW, LiLash Purified Eyelash Serum, NULASTIN Eyelash Serum, RevitaLash Advanced Sensitive, LiBrow Purified Eyebrow Serum, neuLASH (3.2 mL), UKLASH Eyelash Serum, Borboleta Brow Serum. RevitaLash reformulated in December 2024; the current Amazon listing for RevitaLash Advanced still prints a prostaglandin analog. Its Peptide Complex+ lists none. "Bought last month" is Amazon's own count on October 19, 2026.

18 more prostaglandin-free serums sell less; they are not shown. Castor oil serums are on this list because they have no prostaglandin analog, not because they grow lashes. 13 more best sellers did not print a full list anywhere we could find, so we could not check them: Tistees Lash Serum, LifeCell Lash & Brow Serum, DIME Boost Duo, Luxe Cosmetics Eyelash Serum, Winxlum Eyebrow Serum, Nanolash, UKLASH Sensitive, ETUDE My Lash Serum, Lancôme Cils Booster, BIYSBER Advanced Eyelash Serum, MIYA LASH, Abera Misan Eyelash Serum, Eveline Lash Booster.

• Latisse (bimatoprost 0.03%) is the only brand-name lash product FDA has approved, in 2008; a generic now exists, also by prescription. Its label says it treats thin lashes "to treat hypotrichosis of the eyelashes by increasing their growth including length, thickness and darkness." In its trial, 78% of users' lashes improved by at least one step on the trial's lash scale at 16 weeks, against 18% on a plain solution. It needs a prescription. The label lists eye itching, eye redness and darkening of the skin around the eyes, possible "increased brown iris pigmentation which is likely to be permanent," and, after approval, reports of "periorbital fat atrophy" (a hollowed look around the eyes).

• The EU's safety committee (SCCS/1680/25, final opinion February 2, 2026) said of isopropyl cloprostenate, methylamido dihydro noralfaprostal and dechloro dihydroxy difluoro ethylcloprostenolamide: "none of them can be considered safe for use in cosmetic products intended for promoting the growth of eyelashes and eyebrows."

• The UK government (December 5, 2024) reviewed 110 lash serums sold online; 23 declared a prostaglandin ingredient. UK report
• The US: FDA seized Age Intervention Eyelash, which contained bimatoprost, as an unapproved drug (2007), and FDA warned the maker of RapidLash and neuLash that its isopropyl cloprostenate serums were unapproved drugs (2011), from trade press; FDA’s own pages did not load. Today prostaglandin lash serums are sold as cosmetics.
• Hidden ingredients: Sweden’s medicines agency found a prostaglandin analog in 3 of 26 lash serums whose labels did not list one (2013, cited in the UK report).
