How do I use the two ends of the applicator?

Use the precision tip to trace the upper lash base or target sparse-looking brow areas. Follow with the spoolie to distribute the serum through your lashes or brows.

How often should I apply it, and when does it fit into my routine?

Apply it once daily to clean, dry lashes and brows in your morning or evening routine. Let it dry for 1–2 minutes before moving on to skincare or makeup.

Can I apply makeup after using the serum?

Yes. Let the serum dry for 1–2 minutes first. It may also be used as a conditioning primer before makeup.

Does the serum feel sticky or leave a visible coating?

It has a clear, lightweight texture that absorbs quickly without sticky residue.

Is it suitable for sensitive eyes?

The formula is pH-balanced, and brand-published clinical testing reported 0.0% skin irritation around the sensitive eye area. Individual sensitivity may vary. Avoid direct eye contact and discontinue use if irritation occurs.

PRODUCT DETAILS

A little care for lashes and brows that look dry, fragile or less full. This daily conditioning serum helps both areas look fuller and more resilient.

At its heart, a seven-peptide complex supports the appearance of thicker, fuller lashes and brows. Biotin, panthenol, sodium hyaluronate and Centella-derived ingredients complete the conditioning blend, helping moisturize dry, fragile-looking hairs for a softer, stronger-looking finish.

The clear texture absorbs quickly and feels lightweight without sticky residue. It can also serve as a conditioning primer before makeup.

The dual-ended applicator gives you precision and even distribution, pairing a fine tip for the lash line and sparse brow areas with a spoolie for lashes and brows. The formula is made without prostaglandin analogues, parabens, sulfates or oils.
