Published: 21-Oct-2021

In partnership with Schwan Cosmetics

Schwan Cosmetics‘ BOOST Enhancing Serum Liner is a 2-in-1 high performance liquid liner which also provides fuller, thicker lashes and brows.

The texture is proven to deliver 20%1 more lashes and 18%2 thicker brows while entirely avoiding controversial ingredients.

BOOST is available in a transparent version for day and night treatment, as well as a coloured eyeliner and coloured browliner.

For an eye-catching look and a voluminous lash line, many consumers turn to either eyelash and eye- brow serums or colored liquid liners.

Schwan Cosmetics strongly believes that cosmetics should not compromise beauty or health.

The BOOST Enhancing Serum Liner underlines this believe: It combines a proven active ingredient complex of 3.75% care ingredients for more and thicker eyelashes and brows with color pigments for the daily make-up look.

Proven ingredients such as panax ginseng root extract and sodium hyaluronate are essential in the formula to intensively nourish and moisturise the hair.

Panax ginseng root extract is known as a powerful natural stimulant for hair growth. It is famous for promoting healthy eyelashes and eyebrows and works directly at the root, conditions and reduces hair breakage and supports growth.

Originating from biotechnology, sodium hyaluronate is known to moisturise and strengthen hair roots.

It deeply nourishes the entire hair follicle to prevent premature hair loss. At the same time, caffeine is known to stimulate blood circulation, which can lead to improved hair growth directly at the root during the initial stages.

Longer growth phases thereby can contribute to a thicker and denser appearance.

The texture is vegan, cruelty free, ophthalmologically tested and any controversial ingredients have been strictly avoided.

BOOST Enhancing Serum Liner is available in three different versions:

  • BOOST Enhancing Serum Liner
  • LASHBOOST Enhancing Serum Liner
  • BROWBOOST Enhancing Serum Liner.
