Description +

Strong, long, and healthy eyelashes and eyebrows are the ultimate face-defining feature.  This high potency, clean, non-toxic lash and brow serum will help stimulate and nourish your eyelashes and brows better than ever before. Free from prostaglandins and doubling up as a styling serum, this revolutionary product is perfect for day time wear and adds shape to your brows as well as gloss to your lashes in a way that other growth serums do not - all without impacting the delicate eye area with dark marks and circles that many growth serums can leave behind.

Backed by patented, trademarked, and active ingredients and hydrating, reviving, and shine-inducing superstar players, Agent Nateur's Lash and Brow serum is scientifically formulated to deliver ultimate nourishment that strengthens, conditions, and enhances eyelash and eyebrow follicles from root to tip.

Improving flexibility, moisture, and shine, as well as helping lashes and brows to appear dense, fuller and more beautiful, this natural brow and lash serum is perfect for anyone who wants to strengthen and nourish a fuller, healthier and more vibrant set of eyebrows and eyelashes. And the even better news? It can be worn under mascara for a double dose of brow and lash power.

The Agent Nateur Lash and Brow Serum is particularly powerful for those with brittle or short lashes, inconsistent / sparse lashes and brows; or those who want help with day to day styling.


  • Follicusan™ - A patented, science-backed, clinically proven and studied active ingredient.  Follicusan™ is a milk-based bioactive, containing active signaling molecules, which clinical studies have proven to stimulate cells and vitalize eyelash follicles, helping to improve both eyelash density and volume.
  • Capixyl™ - A second, patented, active ingredient Capixyl™, a peptide combined with a plant-based red clover extract (densely rich in Biochanin A) has been scientifically proven to work deep into the hair follicle to stimulate, strengthen and regenerate eyebrows and eyelashes, to deliver a thicker, more luxurious and longer look.
  • Redensyl™ - A third active ingredient, Redensyl™, is also called ‘human hair galvanizer’ and targets the root causes of unhealthy hair. Made up of pure plant extracts and fully natural ingredients (including DHQG and EGCG 2), Redensyl™ works to promote and activate the division of bulge stem cells, helping to promote hair growth.
  • Hibiscus - Derived from the Hibiscus rosa-sinensis plant. Hibiscus is a powerful hair remedy, supporting longer and thick-looking eyelashes and brows, packed with antioxidants, flavonoids, amino acids, Vitamin A, C, mucilage fiber, and more.
  • Amla - Derived from the Indian Gooseberry, Amla is a potent ayurvedic fruit that has been a staple secret of beautiful hair in India for over 5 decades now. Rich in Vitamin C, natural antioxidants, polyphenols, and more, amla conditions hair from root to tip, the perfect conditioner for hydrated, moisturized, and shiny lashes and brows.
  • Bhringraj - One of the most popular Indian hair ingredients, derived from the sunflower family and created by the wisdom of the ancient Hindoo medicine practices, Bhringraj is a shine-inducing ingredient that cares, nourishes, and heals eyelashes and brows. Packed with Vitamin E, flavonoids, phytosterols, and coumestans - all-natural compounds that work together to promote the appearance of dense and voluminous eyelash and eyebrow hair follicles.

Size: 10 ml


Apply to clean lashes. Swipe on a few layers of product from the root of lashes to the tips. Apply mascara afterwards if desired.

Apply to brows and lashes morning and evening and style as usual. This pro-growth serum doubles as a styling serum and can be used before mascara. 

If irritation occurs, rinse with water and discontinue use.

Jena’s Tips: "I love to pencil my brows, then I apply our serum and apply Anastasia’s lash and brow serum for even more stiffness. The two serums combined give me the best shape!

Sometimes I just use the serum on my lashes to give a sexy, wet look. Other times I wear it under mascara."

    A staple in my routine

    I used to think lash serum was kind of a wash. An added expense that doesn’t really matter. I have used other serums that gave me terrible dry-eye due to toxic chemicals in the formula. I was hesitant but bought a bottle anyway because everything Jena touches turns to gold and this is not exception. My lashes are touching the tops of my eyelids and my lower lashes are the longest I have ever seen them in my life. I’m still on my first tube but just bought a backup in the sale. I feel like a little goes a long way with this. I use it morning and night and it’s been less than 3 months and I still have more product in the tube. Expensive but completely worth it. I can’t wait to get my lashes tinted so I can see them really pop

    already working in 3 weeks

    The pricetag on this product initially made me hesitate to purchase, but I decided to go for it during IB's last sale and I'm SO glad I did. I've been using it nightly for about 3 weeks at this point and can't get over the fact that I'm already seeing results - brows are getting thicker (even my left one which has been more sparsely populated for years) and lower lashes longer. Still waiting for noticeable upper lash results, but I'm certain they will come. Another Agent Nateur winner!

    Great for brows

    I use this at night for my eyebrows. It lasts a long time. This is my second tube of it. Need more time to say if it works for sure.
