I have been using Xlash PRO eyelash serum for about 3 weeks now. I took photos before I started using the product & I’m still amazed by the difference it has made to my lashes. Before use, they were short, stubby & pointed downwards. Now they are long, thick & curl upwards. I grow some lashes in the inner corner by my tear ducts, but I just pluck them out. I know you are not supposed to apply to the lower lid, but I do & my lower lashes are full & long & frame my eyes beautifully. I have had no problems with the product & I can highly recommend Xlash PRO Eyelash serum.

Absolutely the best eyelash serum out there! I bought it on their website because I saw that it is Oil-free and Hypoallergenic tested unlike most of the other eyelash serum brands out there. Natural product, cruelty-free, and made for gentle eyes. I recommend it to anyone looking to boost their lashes using clean ingredients proven to work in just 28 days.


One of the best of Xlash! I can’t get enough of Xlash 3ml so I decided to get this one instead. Saves money.


Can’t ask anything more about this product. It works, delivers real results, and is a great value! Been using this for months now and I still have a lot of the serum left.

I have been using the serum since December 2019.
It’s not the product you see result straight away (within a few days), but after a couple of weeks, I started seeing my lash getting fuller and longer, even my partner thought I had fake lashes on after I curl them and put mascara on. (not joking)
After a few months, I have used it Every second night before sleep.
Really recommend. The serum + a good mascara will be a live changing!!.
I just bought it again!!

Xlash Eyelash Serum is the secret to naturally long, full and healthy lashes. With Xlash, you can say goodbye to high maintenance lash extensions, the struggle of using fake eyelashes, and even the need for mascara. The high-quality serum combines carefully selected natural extracts, potent moisturizing ingredients and powerful active ingredients. Due to the impressive results, Xlash has become Sweden’s best-selling eyelash serum and today Xlash is sold globally. We have satisfied customers all over Europe, Asia, South America and the USA. An Xlash Eyelash Serum * is sold every 30 seconds, and the number of satisfied customers continues to grow. *Based on yearly sales data before the new product launch.

Xlash helps your natural lashes grow in three ways: 1. The moisturizing formula makes the eyelashes look healthier and fuller 2. Active ingredients support your natural growth so that the lashes look longer 3. Soothing, natural ingredients prevent lashes from falling out prematurely The moisturizing ingredients help the lashes become stronger and prevent them from breaking off so that the lashes can grow long. Active substances help the lashes to grow by supporting your natural growth. The active ingredients in our formula are Biotinyl Tripeptide-1 and Dechloro Dihydroxy Difluoro Ethylcloprostenolamide. The formula contains several soothing ingredients that give your eyelashes optimal conditions to grow and prevent the lashes from falling out prematurely. This makes your lashes look longer, fuller and healthier. (If you want to know more about specific ingredients and how they work, read more here.)

Xlash users often see results within just 4 to 6 weeks, but sometimes it can take a little longer. During this time, most of our users are—however—already seeing some of their lashes growing longer, and within 12 weeks the results have been clearly noticeable. Eyelashes grow in three phases, meaning that approximately 40% of the upper eyelashes are in the growth phase at any given time. The rest of the lashes are in different stages and are not growing at the moment but will start to grow again later. This asynchronous growth process of the eyelashes is the reason why you can first start to notice single lashes growing longer than others. However, the other eyelashes will eventually catch up when you continue using the product regularly.
 In our studies, 96,67 % of the users reported that their lashes were longer after 12 weeks of using Xlash. 73,33 % of them noticed the difference already after four weeks.* *30 women, aged 20–56, self-evaluation. Supported by dermatological and ophthalmological tests as well as high-tech tests with UV lamps to measure skin sensitivity.

Xlash should be applied directly to the upper lash line onto clean skin. Xlash comes with a thin, brushlike applicator, which makes it easy to use. We recommend only using Xlash on the upper lash line and avoid the inner corners of the eyes. Applying the product to the lower lash line and inner corners of the eye should be avoided since the serum can spread out easily when blinking. We recommend using Xlash once daily, preferably in the evening. Read more about how to apply Xlash here.
