Clinically Tested Lash Strength: Testing by the Korea Institute of Dermatological Sciences showed an 18.05% improvement in lash tensile strength after one use.

Gentle, Prostaglandin-Free Formula: Formulated without prostaglandins, with sensitive-skin testing and in vitro eye irritation testing completed.

Application

STEP 1 | PREP

Start with clean, dry lashes. Gently remove any eye makeup, mascara, or residue before applying the serum.

STEP 2 | APPLY

Using the specially designed C-curve brush, apply a small amount evenly across your lashes, gently sweeping from root to tip. Use the rounded ball tip to reach smaller, hard-to-reach lashes.

STEP 3 | LET IT ABSORB

Allow the serum to dry completely before applying mascara or other eye makeup.

STEP 4 | MAINTAIN

Incorporate the serum into your morning and evening routine for consistent lash-conditioning care.

Pro Tips:

Morning & Evening: Apply consistently to clean, dry lashes.

Before Mascara: Allow the serum to dry completely before applying makeup.

For Fragile Lashes: Use gentle strokes and avoid pulling or tugging.

Less Is More: A small amount is sufficient for even coverage.

Care for the Lashes Beneath Your Mascara

Your lashes get plenty of attention when it comes to makeup, but often less when it comes to conditioning. Dry, fragile lashes can look less soft and healthy on their own.

Lash Boost Serum adds lightweight moisture and nourishment with a water-gel formula. An easy daily conditioning step for softer, healthier-looking lashes, even on makeup-free days.
