Is the yellow Booster Serum made for both brows and lashes?

Yes. The yellow Brow & Lash Booster Serum is designed for both areas, with a ball tip that reaches close to the roots and a curved spiral brush that follows the direction of the hairs.

What kind of applicator does the yellow Booster Serum have?

It pairs a ball tip for reaching close to brow and lash roots with a curved spiral brush that follows the direction of the hairs.

How should I apply the serum to my lashes?

Place an appropriate amount on the brush, then lift it through your lashes in a zigzag motion from the inner side toward the outside.

Do all four versions work as mascara alternatives?

No. The 001 Black and 002 Brown options are the colored mascara alternatives. The yellow option focuses on daily care, while the gray option is for fixing.

Is the serum line vegan-certified?

PRODUCT DETAILS

One line, four ways to meet your brows and lashes. Choose daily care, fixing, or colored definition: the yellow Brow & Lash Booster Serum is the care option, the gray Lash Booster-Fixer Serum adds fixing, and 001 Black and 002 Brown are colored mascara alternatives.

If everyday brow and lash care is your focus, the yellow serum includes DERMA-CLERA™ and has a soothing care focus for sensitive brow and lash areas. It gives the care option its own clear place within the wider lineup.

The yellow serum's applicator brings together two thoughtful shapes: a ball tip that reaches close to the roots and a curved spiral brush that follows the direction of the hairs. Each part is designed for a different area of your brows and lashes.

The full serum range is vegan-certified. Choose the care, fixing, black, or brown option according to the role and definition you want—a little flexibility, kept refreshingly simple.
