What the gurus are saying

Latisse does grow lashes longer and darker, and works on brows too, but experts split sharply on whether the trade-offs are worth it. The main risk that keeps coming up is periorbital fat loss and hollowing around the eyes, along with redness, itching, and darkening of the skin under the lashes, especially in people with thinner skin or less fat padding. Some gurus say the risks far outweigh the cosmetic benefit for lash use, while others find it tolerable on brows or in people with enough natural padding. Those who do use it often dial back to every two or three days instead of daily to lower side effects, though even that may not prevent darkening or sensitivity. Because Latisse requires a prescription and close monitoring, your prescriber can catch problems early.

"Studies comparing topical minoxidil two percent to Latisse and a lower concentration of bimatoprost found they all grew hair about equally from a physician evaluation, but patients were most happy with the results of Latisse, probably because it also darkens the hair, which makes lighter and blonde hairs look fuller."

"You could even use topical Latisse on the eyebrows and that would also fill in that area. If you're looking for denser, thicker eyebrows, that would be one of my top recommendations and it shouldn't be harmful. But be careful with Latisse, if it gets into the eyes it can change the color of your eyes, if you have lighter eyes it can make them darker, and in some areas it can cause some recessing of the fat."

"If you are using a lash growth serum with prostaglandin analogues for a cosmetic purpose, the risks far far outweigh the benefits. They can cause increased vascularity of the skin, meaning growth of new blood vessels. Often people will find that when they use these really consistently, the margins around their eyelashes become red or purple. [...] They can also change the color of your eye, lead to drooping of the eye, and cause hyperpigmentation around the eyes."

"Latisse has prostaglandins. So for most people, I do not recommend it. Now there are some people who have a lot of excess skin around the eyes that have a good amount of fat around the eyes, they're going to be fine with using something like Latisse. But if you've been using Latisse and you're noticing like, hey, my eyes are looking darker or more hollow, that is often why."

"I love Latisse, it's actually really powerful when used in the right places. I have patients use it on their brows, I also have them use it in their hair and on their hairline so when used in the appropriate locations it does wonders. [...] There is a risk of irritation so it's something to keep an eye out for but in general it tends to be well tolerated in the brow area and if you do happen to notice side effects you can always stop using it and the side effects should resolve."
~Yay
"Instead of using it every day, I use it every two days or every three days, and I don't notice that my lashes are getting any shorter by doing it that way. It helps my eyes stay a little bit more hydrated because I find those can be kind of drying. I apply it after I do my eyelashes, and I put a little bit on each brow with one drop. I haven't noticed any negative effects on my lashes by doing it every two or three days instead of every day."
~Mixed
"Latisse and minoxidil are equally effective for brow growth in women at 16 weeks. Minoxidil might be more irritating, but it might be less expensive, whereas Latisse might cause side effects of hyperpigmentation, potentially perorbital fat loss, and of course will be more expensive. You can buy minoxidil 2% without a prescription, but Latisse requires a prescription."

How To Get Fuller Brows | Dermatologist Tips
"We don't fully know why that is, but it seems to be perhaps related to compelling the hair follicle to get back in the growing phase of the hair cycle. Latisse is FDA-approved for lashes, but it can be used off-label in the brow area for brow growth. We do use it that way for patients who have certain health conditions that cause them to lose their brows, for example chemotherapy. It's been shown to be helpful for getting the brows to come back after chemotherapy."

FAT LOSS & SUNKEN EYES FROM LASH SERUMS 🤔 Dermatologist @DrDrayzday
"I have a lot of reservations with lash serums as a whole, including Latisse, but at least in the case of Latisse we know what to look for and you're being followed by the prescriber for these adverse effects. I [...] am not totally anti-Latisse, but I do have reservations with it. There are risks to be had with it, and I do think it's best to see a health care provider for the prescription so you can be monitored for the development of side effects."
~Nay
"While this number seems really low, I'm a perfect example of that. I have used the prescription and developed significant itching, redness of the eyelid, and redness of the white part of my eye. I just really could not tolerate it. Another side effect is hyperpigmentation, which is where the skin around the lash line gets darker, though this usually resolves after you stop the serum. Another more serious side effect is things like periorbital fat loss, which is around your eyes."

"My eyelashes are quite long because I use Latisse every night, so my eyelash would actually hit the top of my eyelid and [...] I'd end up with like black spots everywhere."

Younger-Looking SKIN in 30 Minutes!?
"Latisse is like an eyebrow eyelash growth serum that's what I used, and it can also darken the skin underneath the eye."
~Yay
"I'm back to using my Latisse. I've never had any problem with it."
~Mixed
"In general you're going to have longer looking lashes. From personal experience I did use Latisse for like a year many years back and that's what I experienced: my lashes fell out less, grew longer, but weren't really fuller. One of the side effects is that prostaglandin can actually induce pigment or melanin synthesis, which is why one of the side effects that we warn patients about when prescribing a prostaglandin serum like Latisse is that you may get brown eye color."
~Mixed
"Latisse is prescription, and these work. I am not telling you not to use them; I am simply wanting you to know the risks here so you can weigh these pros and cons before you start using them. If you are considering an eyelash serum, you need to thoroughly evaluate the label to see if your product contains a prostaglandin."
