    From politics to diets to raising kids, it’s hard to find things we can all agree on. Here are a couple everyone is definitely on the same page about…

    One: every woman wants longer, fuller eyelashes.

    Two: EYELASH SERUMS SOMETIMES WORK.

    That’s right, that ambiguous statement is 100% true. A range of prices, guarantees, and promises all result in one thing: some eyelash serums working and others utterly failing.

    So, how do you know which eyelash serums will help give you longer, fuller lashes and which will have you praying for a miracle that never comes?

    It's all about the ingredients. There are a plethora of eyelash growth serums that can help provide conditioning and even make your lashes healthier but not trigger growth. That's because more serums only aim to hydrate the follicles. ANd while that is important, it won't actually increase the length of the lashes, but only maybe, maybe, give them a longer life (which can make your lashes look fuller, but not longer).

    But you want both: fuller and longer lashes. For that, you need a nutrient and petide-filled lash serum that is proven to activate dormant hair follicles while helping them grow and stay healthy for longer.

    Thankfully for you, we ranked FIVE eyelash serums that should be on your radar. So you can finally stop worrying about which ones to choose, and start thinking about your longer, fuller eyelashes.

    1. OVERALL VALUE: LIAISON LASH BOND

    Liason Lash Bond
    SAVE 50% with CODE SECRET50

    Effectiveness: 95%
    Safety: 90%
    Price: $
    Overall: A

    Liaison has it all, a good value, safe ingredients, and (brace yourself) it works! We tried Liaison after our writers received an the exclusive 50% off discount code SECRET50. We gave it a six-week trial and found our journalist Stephanie Marianne’s eyelashes to have a fuller, longer look. The ingredients are natural and don’t cause irritation or burning, and the instructions are straight forward and simple. It’s really the best of everything packed into one product. Effectiveness, safety, and value all rolled into one.

    2. MOST EXPENSIVE: GRANDELASH-MD

    GrandeLash-MD

    Effectiveness: 89%
    Safety: 70%
    Price: $$$$
    Overall Value: B+

    GRANDELash is probably the most well-known eyelash serum on the market. It’s definitely one of the most expensive. For its effectiveness, it certainly has a hefty price tag, especially with results often being mixed. Some women claim it works wonders for their eyelashes, while many are left with lackluster results.

    3. SAFEST: WOOLASH BY WOO PURE

    Effectiveness: 51%
    Safety: 98%
    Price: $$$
    Overall Value: B-

    WooLash has garnered some great press for its natural ingredients and claims to use healthier supplements to improve your eyelash and eyebrow growth. But does it work? Not so much. There’s about a 51% effectiveness rate, which means you’re flipping a coin on your lashes. At the very least, it won’t burn your eyes, you just won’t have eyelashes people like looking at.

    4. MOST AFFORDABLE: KATE BLANC CASTOR OI4

    Effectiveness: 33%
    Safety: 90%
    Price: $
    Overall Value: C

    Kate Blanc provides a well-concentrated castor oil (yes, that stuff you sometimes cook with). It’s all-natural ingredients make it safe, and there’s certainly no harm in using it. It can help keep lashes healthy, but we haven’t seen extremely great results. If you’re working on a budget, there’s no reason not to use castor oil, just don’t expect miracles. 

    5. THE WORST: YUMI

    Yumi Lashes Mascara Nourish

    Effectiveness: 5%
    Safety: 10%
    Price: $
    Overall: F

    The terrible Amazon reviews might be a tip off, but if you took the risk you’d find unhealthy chemical ingredients, ineffective results, and a quarter-filled bottle that really makes you wonder what you’re paying for. BEWARE, it’s not worth it.
