UKLash Eyelash Serum Review 2025, Before & After + Prime Day Deals

The idea is that biotin peptide helps boost the effectiveness of fatty acids, resulting in stronger and more fuller-looking lashes, while panthenol aims to repair and protect each hair follicle to support healthy re-growth.

Elsewhere, Myristoyl Pentapeptide-17 stimulates the production of keratin, which is a vital protein for hair growth. Unlike the more aggressive prostaglandin-based serums, it leans more moderate — meaning it doesn’t deliver miraculous results overnight, but rather, it focuses on gradual strengthening instead.


My results week by week

Weeks 1

If I’m being honest, there wasn’t anything dramatic to report in terms of results. As expected with any lash serum or a brow growth serum, I didn’t observe any changes during the first week at all, but I do have to point out that I did experience mild redness and itchiness in the first four days of using it.

That being said, since I’ve previously undergone laser eye surgery, my eyes did become more sensitive as a result, so if you’re a bit more cautious about that aspect, you would probably benefit from using the brand’s other iteration designed specifically for sensitive eyes. Otherwise, the formula didn’t feel oily at all. If anything, it felt nice and lightweight, which made sticking to the process that much easier.

Week 2

By end of week two, I started noticing a few “baby lashes” peeking through, but still nothing major in terms of length or volume. Although, given the more conditioned state of my lashes, I noticed that mascara seemed to glide on more smoothly. The sensitivity I felt during the first week had disappeared altogether, which was definitely a plus in my book.

Week 3

The first shift began about halfway through week three. I noticed that my lashes looked darker, more defined and thick (particularly at the tips). It wasn’t a huge change you’d notice from photos or from a friend complimenting you, but it’s definitely hard to ignore when observed closer in the mirror. My lashes looked a bit longer too, though not quite enough to woo me.

Week 4

Now, by end of week four, the results were nothing short of impressive. My lashes visibly gained length, appeared even darker in pigment and denser all around. The “baby lashes” were coming in more aggressively too, which is always a positive sign when it comes to hair growth. But the real test happened when I finally decided to apply mascara and use my go-to lash curler. Lo and behold, a single look at my lashes was enough to make me cancel my appointments with my lash technician on the spot. Not only were they boosted in terms of volume, length and definition, but they appeared healthier and stronger too.


My final verdict

As someone who was going into this review with low expectations, I’m pleased to report that the UKLash eyelash serum passed each test with flying colours. Apart from minor irritations during the first few days, I loved that it was able to enhance my lashes in a matter of weeks and helped me regain the confidence I needed to ditch my lash extensions.

It’s not the “gimmicky” formula that claims unrealistic results with lightning-fast changes — the ingredients work hand-in-hand to deliver improvements that are gradual and lasting. Of course, as is the case with any lash serum, consistency is key. But if you’re ready to commit to using it every night to sustain the results, and if you’re after a less pricey formula that doesn’t compromise on quality, this serum is absolutely one of the strongest contenders around.
