1. Start with clean, dry lashes — remove make-up and contact lenses. 2. Twist open the cap to reveal the curved applicator. 3. Touch the ball tip to the base of your upper lashes, like a thin line of liner. 4. Comb through the lengths with the spoolie to spread the serum evenly. Use once or twice a day, every day — consistency is what makes the difference. One sweep per eye is plenty; more does not mean faster.

A peptide complex, biotin and panthenol (pro-vitamin B5) in a light, water-based serum with plant extracts. Formulated without prostaglandin analogs or hormones. The full ingredient list is printed on the pack — please check it if you have known sensitivities.

For external use on the lash line only. Patch test on the inner arm 24 hours before first use. Avoid direct contact with the eye; if serum gets in, rinse with water. Stop use if redness, itching or irritation occurs. Ask your doctor before use if you have an eye condition, recent eye surgery, or are pregnant or breastfeeding. Keep out of reach of children.

The Sereve lash ritual

Goodbye clumps. Hello, lashes.

Mascara sits on top of your lashes and comes off every night. This serum works the other way round — a light coat at the lash line that conditions every lash, so the lashes you already have look longer, fuller and more lifted.

30 seconds, twice a day

One sweep. That's the routine.

  1. 1

  3. 3
    Comb it throughFlip to the spoolie and comb through the lengths to spread the serum evenly.
  4. 4
    Repeat, day and nightConsistency is the whole secret. Use it morning and night, every day.

Designed for the lash line

Two tips. One stroke.

The curved wand has a soft ball tip for a precise line at the roots and a spoolie for the lengths — so every lash gets coated without serum running into your eyes.

  • Ball tip for a clean, precise lash-line sweep
  • Spoolie to comb through and separate
  • Curved shape follows the eye's natural arc

Yes. Apply the serum to clean lashes and let it dry for a minute before mascara. With extensions, keep the serum to the lash line and follow your lash artist's advice.

It is formulated to be gentle, but always patch test first. Remove contact lenses before applying and wait 15 minutes before putting them back in. Stop use if any irritation occurs.

Yes — a light sweep over the brows once a day conditions brow hairs too.
