One reviewer said compared the product to a more expensive brand called, "Rodan & Fields Lash Boost."

"I have been using Rodan & Fields lash boost for about a year now. I just can't afford it. But with Lavish Lash, I am getting the same results for a fraction of the cost. I have tried a whole bunch of different ones and this is by far the most bang for the buck!"

One buyer mentioned how effective the serum was on their lashes.

"Love this product. It took a few weeks, but then I definitely noticed a difference. My lashes are significantly longer and I get comments on them all of the time (people frequently think I'm wearing fake lashes). After I noticed the growth, I stopped using the product daily and I still have long lashes. It's also super easy-to-use - apply once daily to clean lashes is all it takes."

And another reviewer said they experienced noticeable growth within a short amount of time.

"Lavish Lash added growth and length to my lashes within 2 weeks.Have used the product for at least 6 weeks and my mascara has more to hold on to and the length is improved. Would recommend this product highly."

"I have been interested in a lash lengthening serum but had only heard about a similar product through an MLM. I was always skeptical if results from these types of products are real. So, when I heard could get a similar product that works for a fraction of the price I thought maybe it was too good to be true. But, this product WORKS!"
