So, does The Eyebrow and Lash Enhancing Serum really work? For four weeks, I put it to the test. Read on for my honest review—plus, all the details on Augustinus Bader's latest launch.
Augustinus Bader The Eyebrow and Lash Enhancing Serum
Best For: Nourishing eyebrows and lashes for a fuller, more defined look
Key Ingredients: Red winter algae, biotin, roselle and safflower extracts, hyaluronic acid complex
Product Claims: Improves look of eyebrows and lashes by strengthening hair follicles
The Eyebrow and Lash Enhancing Serum's 2-in-1 formula is result-driven. It features ingredients like red winter algae, which helps promote hair growth and reduce hair loss; biotin, which helps hair grow thicker and faster; roselle and safflower extracts, which target inflammation; and hyaluronic acid complex, which supports overall healthier-looking lashes and brows.
Together, these ingredients should make your brows and lashes look fuller and thicker by keeping the follicles strong and preventing damage—and the brand has the data to back it up. In a 12-week clinical trial, lash length and thickness increased by 34% and 40%, respectively. Eyebrow thickness increased by 55%. Plus, lashes and brows looked healthier—and hair follicle clog decreased by 79%.
How to Use it
You can apply the serum morning and night on clean, dry skin. For your brows, use the wide side of the brush and apply a few strokes of the serum. For your eyelashes, use the thin side of the brush to paint along your lash line, as if you were putting on eyeliner.
I've always been tempted by eyelash serums, but was hesitant to try any. I read once that some formulas can cause discoloration and was too scared to take that risk. Fortunately, the Augustinus Bader Eyebrow and Lash Enhancing Serum is free of the ingredients connected to discoloration, making me feel better about giving it a go.
After 4 weeks of consistent use, I definitely have noticed a difference in my lashes. Although they've always been long, they tend to stick straight out and grow in an unruly way—making it really hard for my mascara not to clump instantly. With consistent use, I feel like that problem has been solved. Plus, my lashes look healthier, with or without mascara.
My eyebrows have never been as much of a focus for me, so I'm less sure how much improvement I've seen there. I do think that they look healthy, and I no longer feel the need to always use brow gel, but I haven't been completely wowed on that front. Of course, that might just be because my lashes are my main concern—and I couldn't be happier with those results.
