Augustinus Bader Eyebrow & Lash Enhancing Serum

A prostaglandin-free Augustinus Bader lash serum, for brows as well

Augustinus Bader The Eyebrow and Lash Enhancing Serum is one serum for lashes and brows. The brand describes it as a gentle prostaglandin-free serum that supports natural growth for fuller, thicker, healthier-looking lashes and brows, built on its TFC8® technology.

Augustinus Bader names it for sparse, brittle lashes or brows. The brand says it helps strengthen and nourish hair follicles for fuller brows and lashes, helps reduce shedding, and locks in moisture to revive brittle brows and lashes. It says the serum functions well as a brow and lash makeup primer.

The ingredient list carries biotin, hyaluronic acid, panthenol, castor seed oil, and safflower and hibiscus flower extracts. The brand lists it as fragrance-free and vegan, and free from parabens, sulfates, silicones, phthalates and mineral oil.

The brand applies it morning and evening with a two-sided brush: the wide side on each brow, the thin side along the lash line. In its routine the serum comes after the eye patches and before the rich eye cream that follows it.

Augustinus Bader's last step is to follow with your usual routine from the rest of the Augustinus Bader line.

What Augustinus Bader reports after 12 weeks

In a 12-week study of 60 men and women aged 18 and over with self-perceived sensitive skin, the brand reports that lash length increased by 34%, lash thickness by 40% and eyebrow thickness by 55%.

These are the brand's own figures. Its page credits the same consumer agreement results to two different studies, so those are left out here.
