"I've always believed beautiful lashes should never come at the expense of healthy skin.
Too many lash serums rely on hormone disruptors and prostaglandins that can cause unwanted side effects. I wanted to create something better. A formula powered by advanced plant science that works in harmony with your natural lash cycle, caring for the delicate eye area while delivering real, visible results.
Lashful combines seven targeted actives with conditioning skincare ingredients to help lashes look longer, stronger and healthier over time, so you can enjoy beautifully defined lashes with total confidence."

Discover the potent ingredients that deeply cleanse, strengthen, and restore your skin – this is where science meets self-care.
At the heart of our Smoothing Cleanser is jojoba oil: a golden, skin-loving liquid that closely mimics your skin's own natural oils. That means it deeply cleansers without disrupting your delicate moisture barrier. Rich in vitamins E and B-complex, jojoba oil gently melts away makeup, sunscreen, and daily build-up, while keeping your skin nourished and balanced. It's non-comedogenic (so it won't clog pores), making it ideal for all skin types, from dry and sensitive to oily and blemish-prone. We chose jojoba for its versatility and skin compatibility, but you'll stay for the silky-soft glow it leaves behind.

"I've been using Lashful on one eye now since receiving it. I've not actually noticed any difference in comparison so started using it on my other eye a week or so ago. My lashes do feel wonderful though. Sadly my end came off and Tropic have been amazing returning my email and are now in the process of sending me a replacement."
"I have been using this lash serum religiously for 6-8 weeks and documenting my lash growth. My goodness what a change! They are thicker and longer and you can definitely see a difference with my bottom lash line. I have fairly sensitive eyes, and I have experienced no issues when using this product. I also love the dual end spoolie so you can get the product right on that lash line. Only thing I would say is that because the packaging is solid in colour it’s hard to know how much product you have left, but like all tropic products, a little goes a long way :)"
"I have to say I can definitely see a big difference in my lashes since using the serum. Longer, stronger, thicker and maybe a bit darker. Very impressed. However I have to say that I do not like the applicator. Tricky to use. Mostly end up with far more on the lashes than I feel necessary and the mascara type wand doesn’t seem to hold the serum. Would still buy again but disappointed in the applicator"
"I had been using this product for more than 6 weeks with no visible results and thought that it could be one product I could remove from my skin care routine... but then this morning I noted a visible difference - longer lashes (some sun bleached) and on closer inspection just generally denser and more lashes. It just took a bit longer for me but worth the wait."
"Love this product. I am a 20 year user of lash extensions with alot of broken and not many of my own lashes also over 50. I have been using this product for the past 10 days and have noticed a considerable difference. Nobody has mentioned me not having extensions which they have in the past. HIGHLY RECOMMEND"
"I had high hopes with this product. I wasn't blessed with full lashes and practically have no lashes on the bottom, so I thought this may help them grow. But it didn't work. I even took photos weekly to monitor! I applied the serum every night, and sometimes in the day too for 6 weeks, but no positive results. Just not for me unfortunately."
"When o first started using this I was astounded by the immediate impact. Using it on my lashes leaving for a few minutes then putting my mascara over the top really enhanced my lashes. However, I am perimenopausal and have very recently started suffering from dry eyes. So now this does not work for me. It isn’t irritating my eyes as such but whatever the active ingredient is to enhance eyelash growth is not compatible with my dry eyes which I’m sad about. I’ve been recommended some remedies though such as Omega 7 with Buckthorn and hot flannels so once this problems stops I look forward to trying this product again. I love Tropic. Just wanted to bring this to Tropics attention."
"Worked for me great lashes documented photos with my ambassador but very disappointed how long it lasted for the cost, used morning and night as per instructions 6 weeks usage costly compared to how long other products usually last, have been with tropic over 2 years and this initially impressed but I couldn’t justify the cost every 6 weeks"
"tried for 5 weeks + now and no change. Disappointed too in the actual container that often bubbles some of the product out on closing, no matter how careful I am in replacing wand. Also leaked when I had it laying down so have to have it standing up. Eyelashes are probably conditioned but no growth or noticeable change. Wont buy again as expensive for continual use"
"I have been using it for about 3-4 weeks and I’m seeing some improvement in length and volume . sometimes it stings my eyes very slightly . Will definitely keep going with it . Not sure if you should put mascara over the top or not ?"
