Cleanse and dry the brow area before application.

Allow the serum to dry fully (about 60–90 seconds) before layering other products.

Use consistently for best results — visible improvement may begin around 8–12 weeks.

For external use only - avoid direct contact with eyes.

If irritation develops, discontinue use and consult your skincare professional.

Keep out of reach of children.

Always apply to dry skin and wait before layering other products.

Start with clean, dry skin:
Cleanse the brow area and allow it to fully dry before application.

Apply once nightly:
Using the precision applicator, apply a thin layer directly to the skin along the natural shape of your eyebrows—focusing on areas of thinning or sparsity.

Let it absorb:
Allow the serum to dry completely (about 60–90 seconds) before applying other skincare or makeup.

Use consistently:
For best results, apply nightly. With continued use, brows appear fuller, thicker, and more defined over time.

This serum delivers brow transformation that feels effortless, with a clean, nightly routine that enhances what you already have - no makeup, tint, or extensions required. The result? Fuller-looking, healthier-feeling eyebrows that frame your face and elevate your features.
