System Verdict

A prostaglandin-analog lash serum with real growth-potential claims—but not a risk-free “vitamin serum.” The efficacy score of 4.1/5 is driven primarily by Isopropyl Cloprostenate, the formula’s featured prostaglandin analog; the panthenol, glycerin, amino acids, sodium hyaluronate, and botanical extracts mainly support conditioning and hydration rather than proven lash growth. The ingredient list does not disclose concentrations, so the analog’s actual dose and performance cannot be independently judged; magnesium ascorbyl phosphate and tocopheryl acetate appear too low in the list to drive a meaningful lash-growth score. The safety score of 3.9/5 reflects the alcohol-containing eye-area formula, potential irritation from accidental ocular exposure, and the pharmacologically active prostaglandin-analog category despite the brand’s reported safety testing. The brand specifically instructs users to avoid eye contact and says not to use the product during pregnancy or nursing, with glaucoma or cancer treatment, or under age 18.
