What is in it
A better supporting formula than we expected: sodium hyaluronate third, biotin and panthenol high, then octapeptide-2, copper tripeptide-1 and polypeptide-23 after the active. Fourteenth is isopropyl cloprostenate — one of the three compounds the SCCS concluded cannot be considered safe in cosmetic lash products, and the one most often named in reports of eyelid darkening and orbital fat loss. Unlike RevitaLash and GrandeLASH-MD, RapidLash does not annotate it on the label.

How it performed
Solid rather than remarkable. Visible change from week six, with moderate length and density gains by week twelve — a step behind XLASH and GrandeLASH-MD on the same class of active. Two testers reported mild irritation.
Who it is for
People who want an analogue serum from a familiar high-street name. Same exclusions as every ICP product: glaucoma, prescribed eye drops, pregnancy, breastfeeding, light irises.
