Formula Details
This serum shares the same water-based, prostaglandin-free base as our lash serum and adds Hydrolyzed Keratin alongside Biotin and Peptides, in a formula designed for daily use on brow hair.
Dermatologically tested and developed with a formulation chosen to minimise irritation, it is suitable for regular use as part of your brow care routine.
Warning Before Use
- For external use only.
- Avoid contact with eyes.
- Do not apply to irritated or damaged skin.
- Do not share the applicator.
- Keep out of reach of children.
- Discontinue use if irritation occurs. If symptoms persist, seek medical advice.
Full ingredient list (INCI)
Aqua, Butylene Glycol, Glycerin, Propanediol, Phenoxyethanol, Hydrolyzed Keratin, Betaine, Panthenol, Sodium Hyaluronate, Aloe Barbadensis Leaf Juice, Ethylhexylglycerin, PPG-26-Buteth-26, Biotin, Glucose, Urea, PEG-40 Hydrogenated Castor Oil, Fructose, Hydrogenated Starch Hydrolysate, Sodium PCA, Sodium Benzoate, Citric Acid, Potassium Sorbate, Glycine, Glycolic Acid, Hydrolyzed Wheat Protein, Lactic Acid, Lysine, Malic Acid, Sodium Glutamate, Tartaric Acid, Arginine, Oleanolic Acid, Biotinoyl Tripeptide-1.
PEG-40 Hydrogenated Castor Oil is a water-soluble, ethoxylated derivative used as a solubiliser. It is not a free lipid oil; it is used at a low level to keep the botanical extracts evenly dispersed in a water-based formula.
What's inside — and why
- Keratin — the structural protein brow hair is made of. Coating each hair in hydrolysed keratin helps smooth the cuticle, so brows look smoother, more defined and better groomed over repeated use.
- Biotin — a B-vitamin (B7) commonly associated with hair and nail condition. In this formula it supports the appearance of fuller-looking, healthier-looking brows by conditioning the existing hair.
- Peptides — short chains of amino acids that condition the skin at the brow line, helping create a fuller-looking appearance over time without acting on hormone pathways.
- Not inside: no prostaglandin analogues (the class of ingredient used in prescription-style lash serums), no parabens — a cosmetic, condition-based approach rather than a hormonal one.
What to expect
In our own 6-week consumer study of 110 participants using the Eyebrow Serum, participants self-assessed their brows as follows:*
- 91% reported an improved overall brow appearance.
- 90% reported more visible brows.
- 86% reported healthier-looking brows within six weeks.
- 85% reported fuller-looking brows within six weeks.
- 81% reported brows looking more defined.
- Weeks 2–3: brows feel conditioned and look more groomed.
- Weeks 6–8: sparse areas typically start to look fuller and more defined — consistent with the 6-week study results above.
- Week 12: most people judge the full effect at around this point with continued daily use. One tube ≈ 3 months.

FAQ
How long before I see a difference? Brow hairs turn over slowly, so this is a weeks-not-days product. Most people notice softer, more groomed-looking brows first, a fuller-looking brow line at around week 6, and judge the full effect at about week 12 of once-daily use. Apply to clean, dry brows and brush through with the spoolie. Individual results vary.
Will it help over-plucked brows? Consistent conditioning over 8–12 weeks supports the look of fuller, more even brows. It conditions the hairs you already have, so areas with very little hair left will show less of a difference.
Can I wear makeup over it? Yes — let it dry for 1–2 minutes first, then apply brow products as usual.
Can I use it after microblading? Wait until the area is fully healed (typically 4–6 weeks, or as your artist advises), then yes.
Is it the same as the lash serum? Same philosophy, different build: the brow formula and applicator are designed for skin coverage along the brow line.
How long does one tube last? About 3 months of once-daily use on both brows.
Is it suitable for sensitive skin? The formula is dermatologically tested with a formulation chosen to minimise irritation, making it suitable for most skin types. As with any new skincare product, we recommend a small patch test first if you have known sensitivities.
Can men use it too? Yes — the formula and application are the same regardless of gender; it's simply a brow-conditioning serum.
Do I need to stop using it once I see results? No. Because the serum works by conditioning the hair you have, most customers continue using it as part of their regular routine to help maintain the appearance they've built up.
How is this different from brow serums that contain prostaglandins? Prostaglandin-analogue serums work on a hormone-like pathway and typically carry warnings around eye pressure and pigmentation changes. Our formula takes a cosmetic, condition-based approach instead — no prostaglandin analogues, no hormone pathway involved.
Can I use it if I'm pregnant or breastfeeding? As a general precaution with any cosmetic active, ask your doctor or pharmacist before starting a new product while pregnant or breastfeeding.
Will it interfere with brow tinting? No — it can be used alongside brow tinting. We recommend applying the serum after tinting sessions rather than immediately before, so the tint isn't diluted.
What customers say

I wanted my eyebrows to look fuller; the hair, especially along the top, was very fine and sparse, and it didn't seem likely they would ever thicken up. This serum is like a miracle—my eyebrows, which used to look so wispy, have truly transformed into a completely different set of brows.
I noticed a difference in the condition and fullness of my brows after nearly six weeks use. I have ordered and received my second brow serum.
I think it will now be a staple in my daily routine.
I’m totally shocked! You don’t think a product is doing anything until you do before and afters!
I didn't have sparse brows, but they weren't as full as they used to be. After a few months of regular use, they look thicker and more even across the whole brow. I've cut right back on using brow pencil because they already look much fuller on their own.
