My number one obsession
I have never swore by a product before with as much passion as I do for lash boost. Legitimately hate having to tell others my secret weapon but wouldn't want to prevent spreading the word to all women that there's one product out there that actually does what it claims it does. I remember looking a...

Not sure how to feel
I've been using this product for over three weeks already. I haven't seen a change in my lashes although I've been using it exactly like the instructions say. It's unfortunate that for the cost of the boost, the bristles already spread to the sides which sort of causes the product to come out more t...

Works but has its cons
I have tried multiple lash serums and this is the only serum that worked so fast and had my lashes looking SUPER long and full. I will always recommend this to others. Something I did notice was that bottom lash line/eyelid appeared darker since using the product. I give it a 10/10 for it's effectiveness but overall a 8/10.
..addicted…
My best friend who has the most beautiful longest lashes swears by this product.. Everytime im with her she gets so many compliments. Well, for christmas she surprised me with my own!! I have been using this profuct pretty consistenly before bed for now 2 months, and now I get compliments!! I am shocked. Expensive but worth it!
Yikes
I bought Grandelash and Lashboost for content. Grandelash had no negative side effect and did better for HALF THE PRICE. I'm glad this is sold at ulta for easy returns though! Lashboost is the epitome of expensive isn't always better. What a joke.
Hard pass
Do more research before purchasing (lawsuit). Big mistake! Eyes burned immediately after applying to eyelid/upper lash line. Unless you want a mid lashes & red eyes, skip this junk! There are cheaper & better alternatives.
Love it. Really works
