People who have tried many different lash and brow growth serums say that none work like this one. A dermatologist called it great as well. Not many gurus have weighed in yet, so there is not much to go on so far, but both of these takes point to real visible results on the lashes that make it stand out.

"This is the best deal I think in the whole sale, this BOGO on the Revitalash serum. It does contain prostaglandins, so if you're prostaglandin sensitive or prefer not to use them, you need to know that, but if you're a Revitalash fan, this is a fantastic deal."

What REALLY Grows Eyelashes Over 50? 6 Month Trial Using A NEW Lash Serum!
"I used Grande Lash, didn't really help much. I used RevitaLash, which was great, and I alternated it with the bimatoprost for years, I think a good two years, with nice results. My lashes were dense, my brows were dense, were slightly improved in color, so I was very happy with that combination until most recently they came out with the studies about the fat loss and I did the reading and it really seemed like that was a consequence of using prostaglandins."

"The last step in my skincare routine is my lash serum. I use the RevitaLash and I alternate that with my Bimatoprost to keep my lashes growing and conditioned. Both of these products do have prostaglandins, and of course the Bimatoprost is prescription. It's not coming off right now, but it keeps kind of coming off, the dispensing kind of comes out really quickly, so be very gentle if you're using this and you're trying to dispense a small amount, it comes out very quickly and you can't lock it."

"Related to hair is the bimatoprost serum that I use, that's a prescription serum for lash growth. It does have prostaglandins and I know some people can't use it and prefer not to use it, but I alternate that with a lash serum depending on what's in rotation. Right now I'm using the RevitaLash Advanced Eyelash Conditioner, but I may have to take a break from that. It seems the RevitaLash seems to be irritating my eyes, and I'm considering trying a new lash serum."

"My favorite lash growth serum, RevitaLash, is in the sale this year as a buy-one-get-one, a two-pack for $100, normally $200. This stuff is expensive, but it works so so well. I've been using it for years, I don't think I'll ever be without it. One package of two will last an entire year."
"I always put on my RevitaLash Advanced, this is my lash and brow serum. I love that it is a prostaglandin analog, so if you're opposed to that you won't want to use this."

"This year they're not offering a two pack of the lash growth conditioner, they're offering a two pack that contains one tube of the lash growth and one tube of the brow growth. I believe the formula is the same thing, it's just that one gives you a tiny little brush like this and the other one gives you more of a doe foot applicator for your brows. I've tried so many other lash and brow growth serums. I always go back to RevitaLash at this point. I'm never switching away from RevitaLash."

"It usually takes me about a year to use up both of those, and I've just finished with the second one. I have repurchased because I love RevitaLash. I've used just about every other lash growth serum on the market and they all failed me. This is really the one that I always go back to. It's got this super tiny little brush and you just do one swipe at the base of each row of lashes, and then I also use this in my eyebrows, and that keeps my eyebrows and my lashes growing and looking good."

"Revitalash Advanced is another product that is frightfully expensive, but again, so worth it. If you're aging and your [...] eyelashes are getting sparse, which was definitely happening to me before I discovered Revitalash Advanced, menopause and everything just robs you of the things that make you wake up and feel like you look like you in the morning, right? [...] This stuff is so worth it."

"I've gone through one tube of RevitaLash Advanced Eyelash Conditioner and I really like this applicator. I love it because it's so thick and it really helps to press it in through the hairs, where just using a tiny, tiny brush doesn't necessarily get as much of it on there. I actually use my RevitaLash on my brows too since I have it on hand. If you're noticing your lashes are getting short and stumpy, this is the best way to keep them growing long and strong."

"I use this every night just one swipe on my lashes one swipe on my brows really grows my lashes and my brows. My brows would be so much sparser than they actually are, my lashes would be really short and stumpy because before I started using lash growth serums they were. This one really works like I've tried different ones I give them six months to work and I end up with holes in my brows and really sparse and really stumpy lashes I always go back to RevitaLash."

"Now that I'm 61 I got to say the facial hair that I want gets sparer and sparser every year and so if using something like RevitaLash Advanced means that I can keep my brows I can keep my lashes that I am 100% using it I love them I have tried lots and lots of different lash and brow growth serums and none of them work like RevitaLash Advanced."

"I love it. I've decided I'm not using anything else because I was sent a sample of Grande Lash and I tried that for a few months, and after a few months of using that, I actually had like a hole in this eyebrow where my eyebrow hair wasn't growing. So I switched back to this a few months ago, and that hole is gone now, my eyebrow is all filled in. This makes my brows grow the best with this, my lashes grow the best with this. I love it. I'm not switching, I'm not trying any other products now."

"They have prostaglandin analogues which is fine, that's an effective ingredient. But the problem with that ingredient is that it has side effects. And in contrast to getting that ingredient from a doctor where you have a prescription and you're being monitored, it's a wild west out there with [...] the cosmetic version, which does the exact same thing as bimatoprost, which is the active drug in Latisse. You've got to be aware there are a lot of side effects that come with using these."
