Enter your details below to be notified when this item is back in stock.

What it does

Our Sensitive Eyelash Serum is specially formulated for delicate skin types, helping to nourish and condition your lashes resulting in longer, healthier and fuller lashes.

Why it’s special

The formulation is supercharged with seven plant extracts, including Camellia Sinensis, Centella Asiatica, and Polygonum Cuspidatum; all of which provide anti-inflammatory properties and are boosted by Hyaluronic Acid, optimising moisture retention in the skin and hair.

Benefits

Gentle recipe - The peptide-based, vegan-friendly formula is infused with seven natural plant extracts and free from parabens and oils; making it safe to use with lash extensions and contact lenses

Easy application - Apply in less than 5 seconds

Clinically tested - Approved by ophthalmologists

Money-back guarantee - In the unlikely event that you are unhappy with the results after 12 weeks of use, we will give your money back

Weeks 1–4: Nourishment Begins
The lashes begin to feel nourished and conditioned as the serum strengthens the lash roots, stimulating growth and making them less prone to breakage.

Weeks 4–6: Visible Changes
The lashes start to look longer, healthier and fuller whilst the serum continues to nourish and condition the lashes at the root.

Weeks 6–8: Noticeable Growth
The lashes appear longer and stronger, showing a clear improvement in both volume and length, while the serum continues to nourish and support the lashes entering the growth phase.

Weeks 8–12: Full Results
Full results are achieved with lashes that are healthier, thicker, longer looking, and nourished, as the serum worked to stimulate growth. To maintain these results, use 3–4 times per week.

1. Remove makeup with an oil-free remover or cleanser.

2. Apply one stroke of the serum only to your upper lash line (like an eyeliner). One dip is sufficient for both eyes.

Using more than instructed will not give you better results and might increase sensitivity: Don't do multiple applications or double dips. Don’t apply it on the lower lash line (the serum will be transferred to your lower lashes when you blink).

3. For best results, apply in the PM and allow the serum to work overnight. If applying in the AM - make sure the serum has fully dried before following with your makeup routine

How often?

  • First 12 weeks: Every day
  • After 12 weeks: 3-4 times per week (every other day)

Important

  • Avoid direct contact with the eyes
  • Do not use if you are pregnant, nursing or under 18
  • Keep out of reach of children
  • Patch testing is recommended and if redness or irritation occurs, discontinue use
  • If you have any preexisting conditions, consult your doctor before use

Reviews Summary
Customers say this lash serum makes their lashes longer, thicker, and fuller within weeks to months of use. Many report dramatic improvements, with some receiving compliments from professionals during lash lifts or being asked if they're wearing false lashes. Users appreciate the sensitive formula for reducing eye irritation, though some find it less effective than the original version. The serum works well for those recovering from lash extensions, aging-related thinning, or other lash loss. Most see visible results within 2-8 weeks of daily application. While the majority are highly satisfied, some experience no change or mild eye irritation.

    The best

    I am very satisfied, to be honest I didn't think this serum would do anything for me but.... it really did, my lashes are much bigger, thicker and when I put mascara on them they are double and gorgeous.. I really recommend it 🥰💝 It's the first time I've given a review to a product and written so much but believe me it's worth it. I only used one bottle.

    Longer and healthier

    After having lash extensions for so long and getting older my lashes were very short, stumpy and blunt. I’ve been using this for about 8 weeks and they’re definitely longer stronger and I can actually see them with mascara on now! They may not seem long to you guys but the were honestly no longer than my bottom lashes before using this serum.

    Brilliant product!

    I wasn’t very confident about buying a product that says you can get longer lashes but I was wrong! This product really works and I’m delighted with my eyelashes! I’m a young 73 year old and take great pride in my appearance, so this was a real find.

    I wish there was something that could make my lashes thicker as they were in my youth but I’ll accept longer!

    Excellent

    I lost all my eyelashes due to alopecia, I started using this serum and I have had such great results!! I am on medication for the alopecia so that is helping grow back my hair, however, since I’ve used this lash serum my eyelashes have grown like mad!! Today I actually used mascara for the first time in months!! 😍 so, so pleased!
