A lash growth treatment serum with a difference. Using our unique Rootboost complex technology, our clinically proven formula supports your hair growth cycle to achieve longer lashes safely and effectively.

Our 4-in-1 formula not only grows new as well as existing lashes, but locks in moisture, prevents damage and supports cellular renewal. 

Used daily, our serum creates an optimal environment for hair growth.  A blend of root botanicals (Ginseng, Pumpkin, Mulberry root and Licorice) work alongside multi vitamins and amino acids to promote healthier, stronger hairs. A trio of polypeptides fortify follicles to stimulate growth, improve hair density, prevent shedding and brittleness as well as creates a protective moisture barrier around the hair shaft for longer lashes. 


Ophthalmologist tested, it’s suitable for contact lens wearers and sensitive eyes alike.

Everyone. Those who want longer lashes. Or you might be looking to regrow them after extensions, chemo, stress, trichotillomania, post covid, post menopausal, post natal hairloss. Whatever the reason, we're here to get you longer natural lashes.

Using our engineered brush, apply directly to the lash line twice a day - on clean, dry skin. You will see huge changes in your lash length and volume in just 3-12 weeks (depending where you are your in growth cycle).

I ditched extensions after years of damage. SOWN’s lash serum made my natural lashes so much healthier and SO much longer within weeks I don’t miss extensions at all. Now my lashes touch my eyebrows!!

I've tried most lash serums on the market... but Sown is the best lash serum out there. I mean JUST LOOK AT THEM! It's not only grown my actual lashes but suddenly loads of lashes appeared so the volume has been insane.

My optician recommended Sown as a safe way to grow longer lashes and i'm SO pleased I took her advice. Trust the process, it really works. I didn't think they had grown that much then suddenly people were telling me how long my lashes looked so I knew it was working!

How to Use

Application Time

3 seconds, 1 swipe, morning and night.

How to Make it a Habit

Keep it by your toothbrush to make it a root-ine!

01.

Apply 1 stroke stroke to your upper lash line at the lash root as you would a liquid eyeliner. Use just 1 dip into the bottle for both upper lash lines

02.

Apply product to clean, dry skin and allow the serum to dry a few minutes before applying additional products.

03.

Apply consistently once a day for the first 3 months and then every other day for maintenance after the first full size bottle is finished. Our serum is so safe on eyes, you can consistently use it (unlike prostaglandin ones).

04.

Don’t apply to the actual lashes themselves, the lower lashline, or the inner tear duct area (as this could increase chances of getting the formula into the eye and does not deliver the formula to the lash root where it is most effective).

How It Works

Good to Know: Hair Growth Cycle

Healthy hair go through a constant natural cycle of growth (anagen phase), transition (catagen phase), resting (where new hairs start forming beneath the surface, also known as the telogen phase) and release (exogen phase, where old hairs shed to make way for new hairs.) Sown extends the growth (anagen) phase but where your individual hairs are in this cycle will determine how soon you see results. This is why some people might start seeing results in week 2, whereas others don't until week 8!

What our derm says

This is one of the cleanest lash serums on the market, which actually works.

  • We believe in a circular economy, so all our serum tubes are made from 30% post consumer recycled plastic (RPET), made from fully recyclable PETG which means disposing in kerbside recycling is easy. Also the small slender shape means we ship easily & efficiently, minimizing our carbon footprint.

    We print directly onto all tubes and boxes to avoid sticky plastic labels.

Got Questions on Root 1? We've got Answers

Absolutely! Unlike a lot of competitors, SOWN is completely safe to use with additional beauty treatments such as lash lifts, extensions, tints and waxing. SOWN is oil free so safe to use with extensions. SOWN provides the perfect base to help your natural lashes stay strong during these treatments and so can enhance the length of time the treatments last on the lashes or brows. Also glue from extensions can take its toll on natural lashes, causing breakage and significant lash loss. Using SOWN to complement your lash extensions, strengthens your natural lashes so you can enjoy your extensions longer. You can even transition to natural lashes if you want to as SOWN is just that powerful!

No, SOWN serums are 100% free from prostaglandin analogues and hormones. We believe in safe, effective growth powered by nature and backed by science. Many lash serums on the market use prostaglandin derivatives (often found in glaucoma medications), which can cause side effects like eye irritation, redness, or even changes in iris color. Our formulas are hormone-free and rely instead on a potent blend of root botanicals, peptides, amino acids, and vitamins to nourish and support natural hair growth—without compromising your health or safety.

Yes, our serums are ophthalmologist and dermatologist reviewed, making them suitable for individuals with sensitive skin or eyes. They are also fragrance free and have no irritants in. We also formulated them to be able to be in the CLEAN categories (this means super clean!) at SEPHORA, ULTA and CREDO. 

Just like no two plants sprout at the same speed, your hairs will grow on their own cycle. Some customers see results in 3 weeks, others closer to 12 — but follow our instructions carefully and growth will come. Consistency = your secret weapon.

    Love this serum!

    This lash serum has honestly been amazing. After a few weeks I started noticing my lashes looking longer and fuller. It feels gentle, applies easily, and has become a part of my daily routine. I’m really impressed with the results!

    SO GOOD

    A few years ago, lash extensions completely wrecked my natural lashes. They were thin, brittle, fragile… and no amount of castor oil, vitamins, or wishful thinking made a difference. I honestly thought I’d just have to accept that my lashes would never grow back.

    I started using Sown’s lash growth serum about a month ago, and for the first time in YEARS I’m actually seeing growth again. My lashes look fuller, healthier, and I can literally see new length coming in. If you’ve ever felt like you “ruined” your lashes and there was no going back… this serum is worth trying. I’m so, so glad I did!

    I am a lash serum convert now and have been telling everyone about Sown!!

    As someone with super sensitive skin, I was nervous. But during the trial I had zero irritation. Just healthy lashes that grew stronger week by week. I am a lash serum convert now and have been telling everyone about Sown!!
