Long 4 Lashes FX5 Power Formula Eyelash Enhancing Serum (3ml) is an advanced lash treatment that utilises an exclusive FX5 formulation to promote longer, thicker and smoother lashes with exceptional vitality. Enriched with Isopropyl Cloprostenate, this ingredient is considered to be one of the most effective compounds in promoting healthy lash growth.

Penthasymin Complex works in tandem with Pro Vitamin B5 to penetrate the lash fibre, giving it a soft & glossy look whilst ensuring healthy growth. Sweet Almond Oil conditions the lashes from the root to tip, making them more flexible and resistant to shedding. Based on self-assessment tests, 97% agreed that lashes were left longer, 84% agreed that lashes were left denser and 77% agreed that lashes were left thicker with regular use. This product lasts approximately 4 months if used once daily. Suitable for contact lens wearers.

Directions of use:

  • Ensure the eye area is clean and dry.
  • Using the included applicator, start at the base from the inner corner to the outer along the base of the lash line.
  • To be used daily before you go to bed.
  • Do not apply inside the eye or on the lower eyelash line.

Has been using it for 2 years now. Really makes a difference for my eyelashes. Can't say it makes them much thicker but longer definitely. And reasonable price at this site. Recommended for all my friends.

Love this product, my lashes have never looked so long

November 14, 2019 |

Only been using this for a week and can see the difference already. Brilliant. We be buying me daughters one too.

October 23, 2019 |

This stuff is brilliant! Used it off and on for a couple of year and you can easily see the difference. It takes a couple of weeks to kick in but with regular use I got to the point I actually had to slightly trim my lashes a few times

the perfect product .. I used before. after a month of use, my eyelashes are long and dark. I recommend

June 25, 2019 |

The best serum I ever had, lashes looks like false ones after using this.

June 21, 2019 |

I was dubious as I've used eyelash products before and no change, but this is amazing! My eyelashes are noticeably longer and thicker, I've been using for about 7-8 weeks and saw a difference after 2-3 weeks but it's getting better and better, I've just bought another one for a back up! looking forward to trying their eyebrow products.

Does what it says. Eyelashes definitely get longer.

At 63 i have thin weak lashes. One eye has some very short lashes that have never grown back since I had lash extentions about 10 years ago. I have used Nanolash, pretty good, Revitalash, average but overpriced and Carepost (sp) from a trusted online chemist abroad, which didn't do much for my lashes. I didn't hold out much hope for Long 4 Lashes as I'd never heard of them and they were so much cheaper, but my budget made me go for it. Even though I'd been using the last of the Nanolash I still had to wait about 4 weeks to see the full impact, though I noticed that my lashes felt stronger in about 2 weeks. My friend noticed last weekend how long my lashes are. I don't need as much mascara and they curl much easier. I've just received my 2nd tube. I had a little bit of stinging the 1st couple of times I used it, but I now wipe the brush on the sides so there's not much excess and I haven't had a problem since.

Really good product. I am very happy

February 16, 2019 |

Highly recommend this lash serum! tried others at a similar price range with no effect. Must remember though that Rome wasn’t built in a day so perseverance is key to get the lashes you want with this one

Amazing! I love it!!!!

January 24, 2019 |

Seems good so far but i've only been using the product for a couple of days so I don't expect to see any effects just yet

Very good product, I heared it works miracles, I hope it will help my lashes grow thick and strong after having the extensions. Doesn't irritate my eyes so far.

January 10, 2019 |

It’s really works , I’m using this product more then year and I see great results! Definitely recommend

January 4, 2019 |

Excellent product and easy to use. I'm having great results from it. Have been using for about 3 weeks now.

December 30, 2018 |

easy to apply, good value for money in comparison for other products

December 19, 2018 |

I've been using this product for 3 months now and the effects are amazing! I was quite apprehensive at first but when I saw my best friends lashes after using this product I was amazed so decided to try it myself! And wow it really works!

December 13, 2018 |

Amazing! I had eyelash extensions and once they had come off, my own eyelashes were quite short and stubby! So I thought I’d give this a go. I’ve used an eyelash serum before and it didn’t really do much so I didn’t really have high hopes for this one but thought I’d give it a go anyway.. I was not disappointed, my eyelashes are so long I didn’t think they could ever get this long. Easy to use; just one quick swipe over your lash line every night! Genuinely works! Bit pricey though..

November 3, 2018 |

Only been using this for a few days so no difference as yet.

October 26, 2018 |

It's amazing! I love it!

So can't comment really.

As someone who wears a lot of fake lashes, my lashes get quite damaged. This serum is amazing and it keeps them looking long and healthy.
