RevitaLash came highly recommended by an aesthetician friend. She apparently forgot who she was talking to because when I saw the $98 price tag on JUST the eyelash serum, I almost lost my mind (even with the 15% refer a friend sign-up discount). Naturally, I came over to Amazon looking for something comparable at a MUCH more reasonable price. I was surprised to discover that RevitaLash had an Amazon store, but was happy to find this combo at about the same price as a full size single. Still pricey, but since she REALLY sold me on the brand, at least I could try 2 (albeit smaller sized) products for the same price as 1. My lashes definitely look better (the results on the brows are negligible, but I've had microblading). I wish I'd taken before and after pics to show. Still, I can't help but wonder if a less expensive product could produce similar results. So, I ordered (and received today) EDIFER Cosmetics, Eyelash Conditioner Serum, Advanced Lash Enhancing Serum, Natural Booster Lash and Eyebrow Enhancer for Growing Beautiful, Longer, Thicker Rapid Lash and Brow (0.17fl oz) for less than $8. I'll take pictures this time & post them over there, so stay tuned. I definitely think RevitaLash is onto something, I just don't think the price tag is justified. We shall see.
