Don’t waste your money on this product

6 months ago

If I could give zero stars I would. I really wish I’d read the negative reviews before buying this product. The applicator is useless. After one application my eye got really itchy then went completely blood shot & had a yellow film over it. It was disgusting. Not using again.

No, I do not recommend this product.

Lash lift

a year ago

I like this product, however I'm not a fan of the applicator brush, the serum becomes clumpy and hard to apply, a mascara brush would be more effective. It does make my lashes seem healther though, and I will continue to use and hope for further lash lift. 🙂

Can cause darker under eyes

a year ago

Since I’ve started using this I noticed I was getting darker under eyes. I’ve done some research into lash serums and certain ones contain prostaglandin to help growth - but this can lead to your under eyes becoming darker!! Wish I had known this before wasting my money on this

No, I do not recommend this product.

I was a bit unsure about this product but I have rarely met a L’Oréal product I don’t like. But I just didn’t feel I had any real benefit from this. I think as I don’t always wear mascara and never have false lashes done it wasn’t designed for me

Not a huge difference

a year ago

Have been using this product for several weeks now and to be honest I have not seen a huge difference. They are neither thicker nor longer and the only difference is there is less lash loss. It’s quite tricky to apply and I found that the product made my eyes sting if I wasn’t very careful in applying it.

Strengthening and conditioning

a year ago

I’ve been using this for several weeks now and I can see an improvement in the condition and length of my lashes. Also, fewer of my eyelashes fall out, so it is definitely working. The serum is very lightweight and doesn’t sting my eyes. I prefer this style of packaging as I find the serum goes everywhere when putting usual wands back in the tube. I’ve also used it on my eyebrows and can see a patch that never wanted to fill in has a few more hairs growing there. I would recommended trying this one out.

Seen a slight difference

2 years ago

I have enjoyed using the lash serum. I going the twist bottle easy to apply to the lashes, although sometimes a little too much of it came out of the bottle . I have been using it for four weeks and may have seen a little difference in my eyelashes, but maybe not as much as I thought I would. Maybe I need to use if for slightly longer.

Didn’t feel the product made much difference to the volume or length of my lashes. The applicator also isn't the easiest to use to distribute the product. Apparently effects are supposed to be visible after 5 weeks but so far no luck.

Definitely worth a try

2 years ago

This you have to try. As I age my lashes have become thin, fall out easily and don’t grow as long as were. I haven’t tried a product like this before so wasn’t sure if it would make much difference. Well I’ve been using this very easy to use treatment a few weeks now and I can see the difference already. They do look more fuller, more conditioned and have grew in length a little. I will continue to use to see if it improves the length of my lashes.

Pure magic!

2 years ago

I’m currently undergoing chemotherapy, I’ve unfortunately lost my hair, I’ve always had long lashes that are regularly complimented so I’ve had everything crossed that I won’t lose my lashes. I’ve been consistent in using this product in the hope it would help me retain my lashes. So far, I’m pleased to say after 4 weeks of use I still have all my lashes and they appear to be in excellent condition, so I really couldn’t be happier! The packaging is very luxe but in my opinion it should be gold as for me it’s been worth its weight in gold!

Not my favourite

2 years ago

I’ve tried a few different lash serums before this one and the brush is normally thin like an eyeliner brush for easy application, this one is thick and more like a nail varnish brush which meant it was harder to apply. The instructions said to put on from root to tip which is also unusual as it’s normally just the lash line. I found it really hard to apply this as a lot of product comes out at once. I found once it dried the product went flakey looking like dandruff. My lashes did appear to fall out less when I cleansed mascara off but I don’t think it made any difference to the length.

Amazing serum for long, luscious lashes

2 years ago

I have used other lash serums in the past so was excited to try this one as L’Oreal never fails to impress! It’s super easy to apply. You have to wait a few weeks to see the full results, as the lashes reach their full cycle. My lashes look longer and are more conditioned. I now use it every few days to maintain the look. Very pleased and I’ll buy again.

Stronger lashes

2 years ago

Years ago I got flash lashes fitted which was the worst decision ever made! I was left nearly bald. I've been so cautious with them left and gradually they regrew. This has made them so strong! Barely any fall out anymore, more volume even with bare lashes and strong curl and definition to them. Don't go a day without using it now.

Not for me but has it's pro's..

2 years ago

Not sure I noticed much difference with this tbh, I stopped bothering with it after 5 weeks of no difference. I have given it 2 stars though because it's very gentle on the eyes compared to other lash growth serums and very easy to apply with the type of brush you get, you can easily rub it into the lashes and I never got it in my eyes unlike other products lol. Maybe I was impatient with this one but I've seen quicker results with other lash growth products.

This lash serum definitely leaves your lashes feeling hydrated however I am not entirely sure that it actually made a difference to the length or thickness of my lashes. It can also be tricky to apply as there seems to be a blob of product that comes on to the brush which is difficult to control.

My lashes look so much longer, healthier, darker and stronger since using this serum. I feel like I have much more volume than I did before and I have noticed that not as many lashes fall out.

I’ve used it now for over a month and I’ve noticed a small improvement in my eyelashes. I’m usually very sceptical of growth serums like that but decided to give this one a go and I wasn’t disappointed. Let’s be realistic it won’t give you super long eyelashes like ads show you but it will improve the condition of your lashes slightly.

I have been using this lash serum for a few weeks now & I feel my lashes have benefited from using it, I feel they look thicker, slightly longer & more nourished & I have definitely noticed less lash loss. What I like too is that as a contact lens wearer it did not irritate my eyes or affect my lens, which is a must have for me with any eye products/make up.

Moderate improvement in lash health

The twist dispenser of this product is really useful, applicator is gentle and works well for applying the serum to your lashes. Texture is nice and after applying the serum to my lashes for a few weeks I have seen a little improvement in eyelash health, thickness and therefore length. Not blown away by the difference but perhaps with continued use it will keep getting better.
