Early verdict · Few reviews so far

What the gurus are saying

The high concentration of estriol paired with peptides earns praise as a genuinely targeted option for the delicate eye area, where skin thins first. Gurus found it creamy and hydrating enough that a tiny amount goes a long way, making a 30-gram tube last around three months with daily use. It's described as gentle enough to use every day without irritation from the start, which matters if you have sensitive skin around your eyes.

"I've been using this for about 3 months now and I really love it. So I take a tiny dab of this and I just work it underneath my eyes and onto my eyelids. And [...] the one thing that I love about this is that it's so nonsensitizing. With tret, the gold standard, absolutely love my tret, will never stop using it, but it took a long time to work up to using it and it still can be a little irritating sometimes if I go in a little too hard with it."

"The regular M4 cream is estriol but it's 0.3%. This one is 1% and it's much more concentrated, I assume, because you're only supposed to be using it around your eyes, but it's so creamy and such a nice consistency. And a little tiny dollop goes so far. I ended up using this like all over my face for the whole trip. I mean, I don't want to use it like that all the time. I will continue to use it as an eye cream now that I'm home. This was really awesome."

"They recently came out with an eye version of it. This is a smaller bottle, 30 grams versus the 45, but it's a higher strength of the estriol. It's 1%. And this is a very creamy, very hydrating cream. So you just need the tiniest tiniest amount of this for your eye area. So this will last a good long time. These tubes are supposed to last for about 3 months, and I find that they last 3 months if not longer."

"This is estriol 1%. It's an estrogen cream basically from Alloy and it's a prescription eye cream. I have been using this on my under eye area and I like it. [...] It's very moisturizing. It's a nice formula. It feels good. [...] It's a really nice moisturizer that's been formulated for your eye area with your eye area in mind. But sometimes these ingredients can be helpful in other places."

"They also launched an M4 eye cream with a higher concentration of estriol and added peptides, which I think is a really smart option for a more targeted treatment, especially because this is an area where we see thinning skin and crepey texture appear first."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
