Diablo Cosmetics Reviews 

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!!

I ordered the heavily advertised eyelash serum but after four weeks am not seeing any difference. Disappointingly, the tube feels very empty and I think I'm down to the last dregs already, making this very expensive as well as ineffective.

It’s not often you can buy a product at a great price and get salon results at home. This is so easy, I do it on a Sunday morning with my children running round my feet, it’s easy to do, fairly quick and the results are actually amazing. Whenever I’m feeling a bit frumpy or need a lift I do my lashes and it gives me such a confidence boost. I have really short, straight and fine lashes so if it works for me it would work for anyone. Literally no reason to get this done at a salon with this kit on the market!!

The Diablo cosmetics team is always super helpful, answer really quickly and truly cares about their customers. Have never been displeased with them.

Although the product did not work for me. They were very good on delivery and replying to emails sent.

Very disappointed in the Diablo eyelash serum. I used it every single night for 12 weeks and it made absolutely no difference to my lashes. I gave up using it and ordered some UKlash serum, as I know that really works.

Absolute rubbish. Have been using Revitalist which is very expensive but works. Tried Diablo and within a week I have short thin eyelashes. Don't waste your money.

Sorry I wish I could promote this product but I cant. The eyelash serum hasn't done anything to my eyelashes.

I've been their customer for 2-3 years now. I highly recommend Diablo Cosmetics not only for their products, but also the customer service!

Imran was amazing, he sorted out my issue really quickly with excellent customer service. My package got lost and they offered refund or replacement straight away and I got a voucher!

I appreciated how quickly my issues was taken care of and hope professional the staff is.

Great fast service and the product beats all others I’ve tried, fab!

I ordered the lash serum and it was completely dry ! :(

The customer service is the best I’ve experienced with brands so far.
In regards to the product, I’ve used the lash growth serum for a little while now and I’ve experienced no discomfort whatsoever, so I would recommend it to even those with sensitive eyes who are trying to grow out their natural lashes.

I have bought from Diablo a couple times and love the product. This time my order was marked as delivered but never arrived. I emailed and no one got back to me. Very disappointing customer service.

The Diablo customer service team is top notch. The helped resolve my issue immediately.

Their ads show very lush long lashes, which does set up high expectations, but I do feel like Diablo serum has given me slightly longer lashes, which is better than I’ve had with most other products

Very good customer service! So do not be afraid to buy from the website
