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

Ok where to begin. Having reached an age where I noticed my once good lashes have become short and sparse. Having tried that one extortionately priced serum, it wasn't one that I could afford either.... See more

There's a pretty intense learning curve to do this right but once you figure it out, the stuff really works!! I use it to laminate my brows as well as perm my lashes. The adhesive causes an allergic r... See more

Give it time to work!

I used this product for several weeks without noticing any difference in my lashes. Then, after approximately 7 weeks, I applied mascara one morning and was amazed at how much longer my lashes were! And not only that, but they had a nice upward lift. I just ordered my second tube.

I have used Latisse for years and just tired of the price. I thought I’d try Diablo to see if it worked. ⭐️⭐️⭐️⭐️⭐️
It works better than latisse as latisse did help with length but did nothing for fuller lashes.
I love it and so happy to have something that works with less money.

Really fantastic customer service from Imran

Really fantastic customer service from Imran, I had a problem with Evri delivering my item and the team have sent me a replacement item. Evri finally delivered my order and Imran as a gesture of goodwill for my inconvenience gifted me the extra item. Looking forward to using the Eyelash Serum this evening.
Thanks for your help Imran it’s much appreciated.

The customer service is excellent

The customer service is excellent. If you are not satisfied with the product after 90 days, the customer servicer officer will refund your money without hesitation. Try the product, you have nothing to lose.

Excellent quality for homemade lifts - ADHD proof

Excellent quality. I used to have my lashes lifted at a salon, then it became too pricey for me and I ordered some random option from Amazon. And THEN I stumbled upon Diablo and it’s a game changer. The quality is way better than random unknown brands, lifts last long and lashes don’t shed. I’m a huge fan.

Mind it - i have ADHD and have a grace and coordination of an elephant in a china shop. It gets faster and easier with each time you lift. Practice makes perfect.

This eyelash serum is really good!

This eyelash serum is really good! I’ve used a tube and I’ve seen a difference in the length and amount of eyelashes. I’m also happy it’s much safer to use than a previous product I used. I’m going to keep using Diablo eyelash serum!

Excellent customer service from Imran

Excellent customer service from Imran. He listened to me, understood my concern, and resolved the issue in a timely manner. My package arrived and got damaged by the delivery company. Even though the wait was long, it was worth it as Imran helped replace the damaged item. I'm super excited to try my new kit out. Thank you for your help and great service.

The product works on my eye lashes

The product works! I was reluctant because I have purchased very expensive lash boost products which worked okay. Your product is priced for those of us who cannot afford the expensive ones and it works just as well or even better. I have been using lash products for a while now so I wasn't sure if Diablo could make a difference. It did! My lashes look the best they have! I am so happy I found your product!

Great customer service and fast delivery!

I’ve had a great experience with Diablo Cosmetics. They’re very communicative, my orders arrive quickly, and they’re always helpful when I have questions about their products. I really appreciate how responsive and knowledgeable their team is. Great experience overall!

i swear by the eyelash serum

i swear by the eyelash serum. I lost my eyelashes through illness and the serum helped me greatly, i could see a difference and good regrowth within a couple of weeks. They are great at keeping you informed regarding tracking also. I recommend this company to everyone

Great product

Great product! My eyelashes were thinning and sparse. Diablo eyelash serum brought them back thicker and longer.

One big issue - my lashes are too long and lush

I was sceptical when I first ordered
I had used a popular UK product previously which worked well but caused fat loss under my eyes
I am now on my 3rd order of serum as my lashes are thick, long and have a good curl- my only problem is my lashes now touch my glasses!!

I am in my mid 50s and had started losing lashes- no issues now as I almost look as though I have extensions
