What the brand claims
In the brand’s own words, quoted as written.
“What The Length Lash Growth Serum is formulated with Widelash™, a clinically studied ingredient from Sederma, to help promote visibly longer and fuller lashes with consistent daily use. Applied with a precision eyeliner brush, the transparent serum glides smoothly along the upper lash line for even coverage, delivering visible results in as little as four to six weeks.”
