I've tried several eyelash growth serums over the years. Not one of them made any difference and some of them really stung. However, this is the second Diablo serum I've ordered. It seems to help. My... See more

Posted quickly. Repeat order. Didn't irritate my eyes though saw little improvement in my lashes. However, my brows improved and a small area that was very sparce appears fuller which I am very happy about. I can help thin lashes with mascara but don't like coloured in brows, preferring a natural look so am very happy with the results
I have never had long eyelashes but recently they had really started to think.
I did some research and decided to try Diablo.
It was really easy to use and didn't feel sticky or sting at all.
After two weeks I began to notice a big improvement and now I'm two months using it and my lashes are the best they've ever been..Thank you Diablo 🙂
Even though Diablo claims to be a British company, the products are shipped directly from China. I don't fully trust in the INCI list of unregulated Chinese cosmetic products, the content can be anything. However, I gave the eyelash serum a try, but didn't notice any effect whatsoever on my lashes in 1 month.
Would not buy again, not worth the money.
The only positive thing is that it doesn't sting the eye as some other brands (eg. Xlash) do.

Been using the eye lash serum for about 3 months. The difference is unbelievable. Would definitely recommend.
I ordered a 2 pack of the Eyelash Growth Serum, after having poor results with UK Lash. Unfortunately both tubes appeared to have very little liquid in, so I got in touch with the customer service, thinking that perhaps their was something wrong with the batch number.
Almost by return of email the same day, I was notified that a replacement would be sent out straight awat, which it was, and am now just waiting for the postman!
This is the best customer service I have ever expierenced, absolutely brilliant.
I got mine today after quite a long time and the package looks cheap and just like some cheap China product. This is most likely a dropshipping product and im hesitant to actually use it. Dont know whats actually in there. It sounded too good to be true and probably was

Imran she was Fast solving problems.
Her aim was making a customer happy and great service
Excellent product and service,so purchased a second time. As previously experienced excellent service once again.
A pleasure to deal with the company.
Great communication regarding order and quick shipping. Eyelash serum is working!
I am lucky to always have had long eyelashes, but inevitably as one gets older a serum always helps. I have noticed a slight increase in length since using the serum, even my lower lashes which are long. Good price at the moment and I like no delivery fee!
My eyelashes were disappearing with age but using the serum they have started to grow and thicken. Very pleased with results
I truly appreciate your kind understanding and the refund was there before I thought about it again, thank you:-) My daughter has done it again, so I thought in all fairness we will give it a go as I have sparse eyelashes from treatment, and I think my daughters are fine, but you get that lol I have truly appreciated your understanding, and I understand the US dollars:-)Here goes and thank you again :-)14
Easy checkout and delivery. Everything you need in one box and it even comes with a cute cleanser for your eyelashes and serum. Easy application 15/20 mins start to finish and lasts about 6-8 weeks on me. I used size m x
Been using for weeks and my lashes have not changed at all. Waste of money and time.

Mixed response to this product. The delivery took ages as it came from china which I didn’t realise was the case when I ordered it. The tube feels like there is not a lot of product in it. Despite these 2 negatives, my eyelashes are definitely showing improvement so we shall see!
Trust this company ! The products work wonders, it’s natural too with no harmful chemicals. My lashes have grown 10% longer in just 2 weeks of use.
Great communication when you need to ask questions also !
I shall continue to purchase :)
This product has really enhanced my eyelashes in a way no other eyelash serum has. The growth was rapid. I saw a difference within two to three weeks. The serum is very gentle and has caused no irritation to my eyes whatsoever. The delivery if my order was very quick. I highly recommend Diablo eyelash serum.
A client of mine who also works as a beautician recommended this products for lash lifts and brow lamination treatments. I purchased my first product back in 2025 and have never been disappointed. I highly recommended for those who are in the beauty industry to use and for those who do there own treatments. It's such a super easy product to work with and the outcome from the treatment is always fabulous!!
