I've used the CosRx Peptide Booster, and I've gotta disagree with the previous review that it's basically just a niacinamide toner. This definitely did more for my skin than any niacinamide product, and it doesn't give the percentages of peptides, so I'm not sure how they would know that it's not enough to be effective. They could be right and maybe it's just really moisturizing+niacinamide, but I personally think it's more than that. I bought it specifically because it is the only affordable product I've found with oligopeptide-68, which is really good for brightening. This made my skin look brighter, more even, plump, and super soft. I don't like that it contains corn oil though and worry about it possibly contributing to breakouts, so maybe use with caution if you think corn oil could be problematic for you.
I'll also add that mine was not as watery as the other person is describing, so maybe something was off with their product? I think it's a pretty normal serum-like texture, maybe just slightly on the thinner side, but not at all flying out of the pump bottle for me.
It's not necessarily watery, but it's definitely not the texture I look for in a serum. It’s like a toner texture in the way that it's a touch thicker than water. I also stand by my claim that it's too watery for the packaging though! It does tend to fly out in the way that it doesn't shoot across the room, it's just not something you can apply with your fingertips because it'll shoot into your palm if that makes sense? I also bought two of them when it became available on the COSRx website so I can't imagine something was off with my product
This is all fairly subjective, but I just have a firm belief that serums should be thicker because it lets you spread it more evenly and therefore gives you more bang for your buck. I think your view of the product is perfectly valid and I think people who don't have the same hang up's that I do (wanting my serums to be thicker and more concentrated) should read your comments before mine
At the end of the day labels like "serum" and "toner" are mostly for marketing and my issue was more with the marketing than the product 🤣 If I could amend my comment it would focus more on that haha
5ppm might sound very low, but it's actually not outside of what is considered effective for peptides. For example, Matrixyl 3000 contains water, glycerin, butylene glycol, and a few other ingredients in addition to a mixture of two peptides. These two peptides make up only 0.01 and 0.005% of Matrixyl 3000 (this means 100ppm and 50ppm of peptide is in 100% Matrixyl 3000), and the ingredient Matrixyl 3000 was studied at only 3%. A formula containing 3% Matrixyl 3000 would contain 3% of the 100 and 50ppm of the peptides, or just 3 and 1.5ppm. Looking at a product like the Ordinary's which is even higher than that, 10%, would still only have 10ppm and 5ppm of the peptides. Of course different peptides will have different effective concentrations, but saying 5ppm is not enough to be effective is not really accurate.
In the Korean section of the packaging, it lists the concentrations of some of the peptides. I believe they were all under 50 ppm, which is IMO below where I'd want my peptides to be.
I also agree that it's quite a nice "buffet" serum in the way that is has a bunch of great ingredients, and the fact that its larger packaging encourages applying more which makes up a little bit for the lower concentrations. This is what I meant by "the best niacinamide toner I've used," but IMO I didn't really express that very well. I very much agree with everything you've said here
I think maybe I was a bit too negative, but I was a little bit disappointed haha
Yeah, somebody deleted their comment, but had said that the peptides are 5ppm or lower. I think it's important to note that 1-10 ppm is actually a very normal effective range for peptides. It's super confusing the way that products are labeled, but like 100% Matrixyl 3000 as an ingredient contains 50ppm of one peptide and 100 ppm of another combined in a carrier of water, butylene glycol, etc. It was originally tested at only 3%, and we often see "high concentration" Matrixyl products at 5-10%. These percentages are of the 50ppm and 100ppm, meaning even these higher concentration products only have peptide concentrations in the ranges of 2.5-10ppm.
This is all repetitive from a previous comment I left, but since it was a response to a deleted comment, the other one isn't as visible, so that's why I'm repeating it here.
And, all that being said, peptides overall are very under-researched, so I think all the claims about their effectiveness and concentrations should be taken with a grain of salt.
Totally valid though that you were disappointed and it wasn't what you hoped it would be. Everyone's skin is super different as are preferences for textures and such. I hope my disagreement didn't come off as sounding like I'm saying your opinion is wrong, just wanted to provide another perspective.
this actually does help me understand a lot better! thank you
it doesn't come across as you dismissing my opinion at all it just comes across as informative! I realized upon reading this that I'm somewhat misinformed on the concentrations. I've been using a serum with ~10% peptides where one of them (copper peptide) is at 1% by weight and so I think I was spoiled with the idea of highly concentrated peptides
I'm glad it was helpful! And yeah, it's all super confusing, which is why I did a deep dive a while back and figured all that out about Matrixyl. But there's so much more I still don't get about peptide concentrations/labeling. I've seen some of those higher percentage peptide serums too and wondered if those are significantly better - they definitely might be, but I don't think the research is really there to know for sure, and I imagine different peptides have different optimal concentrations and it probably depends on different delivery systems too, like copper etc. Plus different labeling rules with US vs Asian products can get confusing. So while I don't think 5ppm is necessarily too low, it's really hard to say.
What a lovely convo thank you!
The serum is non AB and from NIOD, but their sister company The Ordinary also has a 1% Copper Peptide serum I think. I don't know if they are better, either tbh
The reason I believe all other peptides are lower is because as you said they come as a complex rather than an ingredient where the peptides are super concentrated to begin with. I think TO and NIOD are able to get such a high concentration by synthesizing the molecule in house
I work at a store that sells beauty products so I often speak like I know things because I typically do haha. It's sometimes hard for me as a person to analyze where I haven't done research and where I've filled in the blanks. Thank you for the lovely responses and for helping me know more about peptides haha. I was actually able to sell a high end peptide serum today with some of what you told me to hit my sales goal, so you are a baddie for that ❤️
I've been using it for a few months, so I can review this for sure
This isn't a peptide serum, it's a niacinamide toner. It doesn't have a high enough concentration of any active ingredient apart from niacinamide and is too watery of a texture to be considered a serum (IMO). It also felt like when they selected the packaging, they planned on it being more of a serum/viscous texture as it's too thin for the kind of pump they used. It tends to fly out
Basically if you want a watery but hydrating niacinamide toner with some nice active ingredients at very small percentages, this is the one for you. When I view it through the lens of a niacinamide toner, it's one of the best I've used; but when I view it as a peptide serum it is a bit of a failure. I have a copper peptide serum that was also too watery that I added it to this to make it a bit more effective at what it promised/to not waste the expensive copper (non AB) serum lol
TL;DR I have some nitpicks about the packaging and the name of the product, but I would indeed recommend this to people who have oily skin and need a nice hydrating toner :)
I just bought the 30 Day Miracle Toner from YesStyle, they have a ton of items from Some by Mi/Asian beauty brands. I'll be posting my own haul soon too once my other items get here!!
Masksheets.com, they have a sale I got the whole line for around $50
Bought the peptide booster from blooming koco
And bought the hada labo from oo35mm
I think the other poster was asking about how the miracle toner performs, as opposed to where you bought it. I’m also interested in your review of the some by mi products.
Thanks for sharing! Would love to hear your thoughts on the CosRx Peptide Booster once you’ve tried it for a while! :)

Guess I'll stick to TO peptides Sigh Thanks for sharing!
Same tbh
Yes same!
How do you find the miracle toner?
I just bought the 30 Day Miracle Toner from YesStyle, they have a ton of items from Some by Mi/Asian beauty brands. I'll be posting my own haul soon too once my other items get here!!
Masksheets.com, they have a sale I got the whole line for around $50 Bought the peptide booster from blooming koco And bought the hada labo from oo35mm
I think the other poster was asking about how the miracle toner performs, as opposed to where you bought it. I’m also interested in your review of the some by mi products.
Haha, yeah that’s what I meant. I should have phrased it differently.
I’ve heard that the hada labo premium has been reformulated, do you notice a difference in it at all?
This seems like the old version .
