*There is a trace amount present (0.0005%) as part of one of our proprietary technology components, which is far below the 1% safety threshold and does not function as a preservative. It doesn’t impact irritation potential, and the formula remains hypoallergenic and suitable for sensitive eyes. (for more context phenoxyethanol functions as a preservative at ~0.5–1.0% so it is 1,000–2,000× lower than functional preservative levels in SOWN and far below what would have antimicrobial activity in a cosmetic.

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.

Just amazing! I have always been so skeptical of lash serums but i did soooo much research before buying one and SOWN seemed to get amazing results but also seemed the safest to use on the eye area. I am so glad i tried this, it's become part of my daily routine!

Thanks to my 2000s overplucking phase, I thought my brows were done for and was considering microblading but was terrified about permanently stunting hair growth. SOWN’s brow serum is the best serum i've tried - they’re so much thicker so look darker too now.

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!

I had a few patchy areas on both brows particularly at the front and have been trying to even them up for ages. And OMG this stuff really works. I was thinking about getting microblading before but don’t need to now as they’re so EVEN now finally plus nice and full and bushy

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 of Root 1 (1 dip is enough for both eyes) to your upper lash line at the lash root, as you would a liquid eyeliner.
02.
Apply 1 stroke stroke of Root 2 to both brows (1 dip into the bottle for both brows is enough), focussing on sparse areas or where you want to grow.
03.
Apply consistently twice a day to clean, dry skin and allow the serum to dry a few minutes before applying additional products.
04.
Don’t apply to the actual lashes themselves, the lower lash line, or the inner tear duct area (as this does not deliver the formula to 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!
The Timeline
Weeks 1-2
Lashes grow in natural cycles,meaning not every follicle is active at the same time. Some lashes are already growing, while others are resting or shedding. Because of this, early changes can vary from person to person. Depending on where your lashes are in their cycle when you begin, some people may notice small new hairs appearing within the first couple of weeks, while others may simply see their existing lashes looking healthier and stronger. Consistency at this stage helps support follicles as they re-enter the active growth phase.
Week 2-4
By weeks 2-4, more follicles begin entering the active growth phase (anagen). As this happens, new lashes start to emerge along the lash line. You may begin to see shorter, finer hairs filling in areas that previously looked sparse. This stage is when early density improvements often become noticeable. Where you see the most growth depends largely on where your lashes were in their cycle when you started using the serum.
Weeks 4-8
As more follicles move into the active growth phase, new hairs continue to emerge while earlier regrowth becomes longer and fuller. By weeks 4-8 and beyond, lashes typically appear fuller, more even, and more defined across the lash line to look more 'fanned out'. Continued consistency allows more follicles to synchronise into the growth phase over time, helping density and length gradually build. To maintain this length and fullness, ongoing use is recommended. Because lashes naturally shed and regrow in cycles, stopping use means new lashes will eventually return to their natural baseline length over time. Unlike many lash serums that are formulated for short-term use, SOWN is designed to be gentle enough for twice-daily, long-term use - making it easy to incorporate into your everyday routine.

Regenerating RootBoost™ ingredients
Our RootBoost™ serums contain a powerful blend of botanicals including Ginseng, White Mulberry, Licorice, Red Clover and Pumpkin supercharged with vitamins B3, B5, B6, B7 (Biotin) C and E to promote healthier, stronger hair growth. A trio of peptides (amino acids) help seal in moisture to prevent shedding and brittleness. Most serums rely on synthetic shortcuts. We harness root botanicals, proven for centuries, and supercharge them with peptides and vitamins for visible, lasting growth.
No prostaglandins. No hormones. Just the proven power of roots.

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? We've got answers.
Yes! Sown serums are safe to use with lash lifts, tints, and brow treatments like microblading and recommended by many technicians. Avoid using brow serums on freshly microbladed brows, especially during the initial healing period (usually 7-10 days). Once the brows are fully healed (after a few weeks), you can start using Root 2 as our formula is clean and doesn't contain any irritating ingredients and won't interfere with the pigment on your microbladed or tinted brows.
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.

I ripped out some of my eyelashes with eyelash curler so was on the hunt for a prostaglandin- free serum, and stumbled across an ad from SOWN. I'm so happy I gave this serum a try, also seeing nice new growth on my brows, but attaching the amazing growth of my lashes to show the before and after in just a few weeks cos LITERALLY obsessed.
Was this helpful? - LLauraI recommend this productRated 5 out of 5 stars6 months agoMy favorite eyelash and brow serum!
I absolutely love this lash and brow serum bundle. My lashes look longer, and my brows have filled in so nicely since I started using them. They’re lightweight, non-irritating, and deliver so good results! Love it!
Was this helpful? - ASAlexus S.I recommend this productRated 5 out of 5 stars6 months agoAmazing!
I’ve been using both serums and I’m blown away by my results! I’ve been having to pluck my brows way more frequently now! What I love most is I’m not a consistent person when it comes to growth serums (I don’t think anyone is unless they really need it) so I’ll use it when I remember but even with that I’ve noticed a huge difference!

On my 8th week and this is true on what it claims. My dermatologist approved of this and will continue to use this as part of my routine :) You're the best Sown!

I've been so insecure with my brows and lash being thin and scarce- I am not really good in make-up , I discovered this set and oh boy, my lash after 6 weeks are fuller, longer and naturally healthier. I'm keeping this routine! Thanks, Sown!
