I've never used a lash serum before but after having extensions for 3 years, my lashes were sparse so decided to give this a go. After diligently using the serum for 3 months, my lashes are thicker and longer and I'm really happy. Only just about to start my second tube also!
Lash Affair has been my favourite serum. I have NO lashes usually, but other serums have irritated my eyes. Now im growing long lashes with no irritation
I was looking for a lash serum without prostaglandin analogues and came across this one, the reviews looked solid so gave it a go. I was not disappointed, it’s just as good as serums with prostaglandins; without the side effects. My lashes are so long, will definitely keep using.
I am roughly 3 months in and absolutely thrilled with my progress so far. At 61 years of age, I was struggling with my lashes becoming shorter and more sparse (as seen in my Before photo)... But not anymore! Love this serum!
I lost my lashes after chemotherapy and although they grew back quickly they were short and stumpy looking. I wanted a serum that didn't irritate my lids and get healthy longer lashes again. I started the serum and within 6 weeks I had stronger, healthier lashes. Now at about 8 weeks I am noticing some real growth which Im really excited about. Very happy with my purchase and couldn't recommend enough
Fist pic is first day and second about 5 weeks after using Lash Affair. It it working. I am noticing lots of length in my lashes at the outer corners especially and also thicker lashes 🙌
I love that this formula feeds my lashes without any nasties. I pop it on last thing at night and don’t wake up with my eyes sticking together! The lash growth is extraordinary as well. Very happy to use this product.
I’ve spent years trying lash serums that stung my eyes or made them puffy. This is the first one that felt gentle and actually worked, my lashes were noticeably longer after just 3 weeks.
My lashes used to shed like crazy after removing mascara but after using this, they feel strong and look thicker. Even better, I ordered in the afternoon and it arrived the very next day. Total game changer
Everything else made my eyelids red and sore. I almost gave up until this. Zero reaction, no irritation at all, and now I get compliments constantly on how fluttery and full my lashes are!
Finally, a lash serum that doesn’t sacrifice safety for results. I’ve avoided prostaglandins for years, and now I’ve found something that’s clean and effective. My lashes look so lush after just one month!
I’ve been using this for over 3 months and I’m still not out! The bottle lasts forever and my lashes are so long now, they literally brush against my glasses!
Didn’t expect much… but WOW. I showed my mum and sister and now all three of us are hooked. It’s a household obsession at this point and for good reason!
My order arrived the morning after I placed it, insanely fast shipping! And when I had a question, the customer service was so lovely and helpful. I felt really looked after.
Every other serum I’ve tried gave me itchy, irritated eyes. This is the only one that didn’t and it gave me real growth in less than a month. I’ll never switch again.
I didn’t expect to see bottom lash growth, but this serum surprised me. I’ve never seen them look this full and now I wear less makeup because my eyes just pop!
I’ve been avoiding harsh chemicals, so this clean formula was a blessing. Even without the nasties, it works like magic my lashes are healthier and longer than ever
Honestly the best lash serum I’ve tried. No irritation at all, which is rare for me – and my lashes are looking fuller already. Can’t recommend it enough!
