Nourishes eyelashes and eyebrows to help them look thicker and darker
- sparse eyebrows

Nourish your way to fuller-looking brows and lashes
Sparse-looking brows and under-conditioned lashes can leave your eyes feeling undefined. Add a simple daily botanical-style ritual designed to help hairs look thicker and darker.
Nourishment where definition starts

Botanical nourishment
Usma grass pulp is paired with pinoside and mustard glucoside to provide cosmetic nourishment to brow and lash hair and support a thicker-, darker-looking appearance. Explore more hair growth serum options for a broader grooming routine.

Targeted application
The dropper format and included black slender applicator tool direct a small amount toward brows and lashes instead of spreading serum broadly. That makes careful eye-area grooming feel more manageable.

Compact daily ritual
The travel-size bottle fits into an at-home or away-from-home routine without adding a bulky beauty tool. Keep it beside your makeup, skincare, or other skin care products.
Your simple daily application
- 1Start with clean hair
Remove makeup and cleanse the brow and lash area. Make sure the hair is dry before application.
- 2Use a small amount
Take a controlled amount with the dropper or black slender applicator tool. Avoid saturating the lash line.
- 3Apply with care
Gently trace the serum through brows and along the lashes while keeping it away from the eye surface.
- 4Let it settle
Allow the liquid to settle before adding makeup or touching the area. Keep the dropper tip clean and avoid letting it touch skin.

A quieter route to definition
When makeup is not enough
Filling sparse brows and coating thin-looking lashes can create temporary definition, but the routine still asks for daily touch-ups. Dry, under-conditioned hair around the eyes can keep the finished look feeling incomplete.
A quieter care ritual
Grass Cilia Nourishing Liquid brings Usma grass pulp, pinoside, and mustard glucoside into a focused brow-and-lash step. The liquid format keeps the ritual simple at home, at the vanity, or in a travel beauty pouch.

Definition, made consistent
With careful, repeated use, brows and lashes look more conditioned, fuller, darker, and easier to groom. It is a calm cosmetic care habit for anyone who wants naturally defined-looking eyes without relying on layers of makeup.
