What the brand claims
In the brand’s own words, quoted as written.
“The XtendLash Booster Serum Mascara is a tubing mascara formulated to deliver intense pigment while supporting lash growth. It combines a lash-enhancing serum with a long-wearing, smudge-proof formula for visibly fuller lashes with each use.”
