6 Peptide Skin Booster Serum.

"I am loving this, you guys. [...] This is the COSRX 6 Peptide Skin Booster Serum. It literally is like water. So when you put this on, you can spread this on your entire body for a fraction of what you would pay for like some of the other types of creams. This is not expensive. I believe this is under $20. It has six different peptides in it, hyaluronic acid, amino acids. Even skin tones, hydrating, firmness, and smooth pore and sebum care, improve skin texture. I've noticed all of that. [...] A peptide pairs very well with a retinoid, so [...] this is great to put on first and then add a retinoid."

"I am obsessed with this product. I gave it an eight out of 10 earlier. Um, I think I'm going to go up in that. I love this because it comes in a pump. This is a six peptide skin booster. It's by COSRX. You can get it at Costco. It's from South Korea. It's great. Use it on your whole body. [...] Can you put this on your face? Absolutely. That's what it's designed for. But why are we not putting it on our bodies? It's basic. I don't want to say it's free, but it's really cheap, you guys. It's not expensive. [...] This is a great product to put everywhere."

"This is the CosRX six peptide skin booster. Absolutely love this, I put it on my whole body. It's lightweight, like a toner, and blends six peptides to address fine lines, uneven texture, and loss of firmness. It's suitable for all skin types, and it's very cost effective, I don't think it's over $20."

"I love this peptide. This is by COSRX, a six peptide skin booster. It evens skin tone, hydrates, helps with firmness and smoothness, pore and sebum care, and improves skin texture. It has [...] a copper peptide in it, [...] signaling peptides, and acetyl hexapeptide-8, so it smooths fine lines, and it's so cheap [...] I've got like six of them in the refrigerator because I use them over everything. [...] I am literally seeing a huge difference just from using this on my body every night."

"It's got some vitamin E in there and soybean oil, so if you have acne prone skin, the main ingredients to be aware of is the vitamin E and the soybean oil. [...] Most people tolerate vitamin E very well even though it's kind of comedogenic, it just sometimes depends on the formula too. Overall it stuff feels nice. I'm really impressed. I'm going to continue to use this because I really like it. The copper peptide in there is very sensitive to other ingredients. [...] I have found copper peptides are very fussy. You're not supposed to use them with almost anything else basically. I mean not supposed to use their retinol, acids, vitamin C, or strong antioxidants. So basically almost anything you use. But I found if I use a copper peptide and then layer a neutral product in between that's not a pH dependent product, that's not an active in between the copper peptide, it seems to work for me and other brands have recommended it, because otherwise you have to choose one or the other. Copper peptides can be very [...] fragile. [...] It's still kind of a relatively newer ingredient in skin care, but I found that works for me and I'd rather do both as long as your skin isn't irritated than have to pick one or the other and only get the benefits from one or the other."

"Next up from COSRX is their 6 Peptide Skin Booster Serum, which is their newer release. It's a wonderful liquid booster, it retails for 21, I kind of use it in place of an essence and it's really absolutely wonderful. I can't wait to do a full review of this one after I've gotten a little bit more chance to test it out. So far so good, so so good."

"I think of this more as an essence than a serum, but it's technically called a serum, the Cosrx 6 Peptide Skin Booster Serum. It's got six peptides as well as several amino acids, it's fragrance free, and a little bit of it goes a long way. The bottle's gigantic and about two pumps is enough for my face and neck. I really think of this more as an essence, to me it's not a serum, but anyway."

"It's really nice but it's very watery so one and a half pumps is usually enough to cover everything really easily and quickly and absorbs almost instantly."

"This one is the Cosrx 6 Peptide Skin Booster. Full of great peptides and ingredients in here. And pretty affordable, very large bottle."

"You've got six amazing different peptides in here to plump the skin, to hydrate it. It's going to minimize fine lines and wrinkles. It's got that Botox in a bottle effect. It's also got PDRN, which is a very, very hot ingredient at the moment. [...] That is a gentle exfoliator, will also fade hyperpigmentation. I think this is a standout, standout peptide serum. Honestly, I might not be a big fan of COSRX, but I'm going to say this, they've done right. It's also really affordable. A lot of their products are sky high in price, this is really affordable, which I personally love and respect. [...] If all your products were that good I would be fully on board."

"The COSRX 6 Peptide Skin Booster is one of my favorites. [...] You get a lot of product with this, which is what I love. Super inexpensive, and that's key. [...] The COSRX one has six different peptides in each one delivering a different benefit."

"This peptide product is so beautiful, so lightweight, not sticky, not tacky, just glides onto the skin. While it hasn't got that hit of copper peptide in here, it has got a plethora of other peptides for just so many different benefits. I love that one. When COSRX does it right, they do it really right, and that for me is an absolute hero product."

"The six peptide skin booster serum is my favorite in this category. I think the concept is derived from the popular injectable skin boosters that are super popular in Korea but in a topical form, and I think [...] that means making the skin more hydrated and more radiant at the end of the day, and I think the formula really does that. It's a wonderful formula [...] because it has peptides and I love peptides. It's a multitasking serum that has six different peptides as the name implies that really helps to promote and improve skin elasticity, texture, radiance, and tone and overall skin vitality. Really designed for those who are seeking a lightweight, almost like an essence, a non-sticky essence or serum that really helps to address all of those concerns in one. The six peptide complex targets fine lines, improves radiance, improves tone, helps to improve skin hydration along with niacinamide, which is a jack of all trades that does a little bit of everything for better skin, and then glycerin that helps to hydrate. All of these ingredients really help target fine lines, skin hydration, support skin barrier, brighten the skin and [...] make your skin look so much better."

"The COSRX peptide booster is one of my current favorites. It's very lightweight, even more watery than the snail mucin, so if you don't like stickiness I highly recommend it. It has a blend of peptides, one of my personal favorite anti aging alternatives to retinoids for those who can't tolerate them, to help target fine lines and wrinkles and support collagen."

"CosRx always has things in the Prime Day sale, and the six peptide booster will be at a discount. I know a lot of us use that and love it."

"The one I'm most psyched about is the six peptide booster. Skinceuticals has a new product out with a bunch of peptides in it, [...] and this has all the same things but it doesn't cost like their product does. I bought this last week at full price."

"The COSRX 6 Peptide Skin Booster is a peptide serum that's very hydrating. It has acetyl glucosamine, which is great for moisture balance, amino acids, and a variety of peptides which may help to a certain extent in helping your skin with its collagen production needs, but at any rate seems to be helpful for improving moisture content. I really like actually using this serum as the first step in a skincare routine after cleansing. It [...] does have niacinamide, which is great for redness, hyperpigmentation, and the moisture barrier, but some of you are sensitive, so if you're sensitive, skip the peptide serum."

"I'm also using the COSRX 6 Peptide Skin Booster Serum a lot."

"The COSRX Six Peptide Skin Booster is a nice hydrating toner, I've already used up a full size bottle, I like to make sheet masks from it. With peptides we still need to establish effective levels and be clear about whether effective levels are in these products, and because of that I didn't rush out and repurchase this product, but I did like it."

"I went through this skin booster the quickest out of everything because I really liked it. It's a very gentle product, it contains peptides, which act as a humectant and maybe do more for your skin, although we don't get much disclosure on the percentage of peptides, which is always very low. Overall I did like it, but I'm not going to run out and repurchase it because I want to see what else is out there."

"I did buy the new Cosrx 6 Peptide Skin Booster Serum. I'm a big fan of peptides and I've been wanting to try more from the Cosrx line. This reads a lot like the multi peptide serum from The Ordinary, but it's really a different concept, more of a toner serum, almost a first serum, and because it's so watery it may help increase the absorption of anything you apply afterward. Peptides are humectant ingredients and we know they're wonderful for hydrating your skin, and the brand claims some other benefits too, though that data is manufacturer supplied. I do believe, by the nature of humectants and the fact that it's just nice to apply, that using this before other serums and ampoules helps. I love my peptides, I love my peptides."

"This is the six peptide skin booster from the COSRX the ordinary line, and it's the first product from that line that's really captured my interest. It's a serum with six forms of peptides plus some hyaluronic acid, natural moisturizing factors and amino acids, and it's really more of a giant hydrating toner at 5.07 fluid ounces. We don't yet have peer reviewed published literature on these peptides, only promising manufacturer's data, so I think it's safer to say the peptides act as humectants rather than overstate the benefits. When you look at the Korean label the actual use levels are pretty low, so I wouldn't rely on this as your main peptide product, but as a booster it gives additional hydration and helps other peptides absorb better. It's so well made that I can use multiple layers of it and my skin doesn't get sticky or tacky. It's really a hit for me."

"If you're just starting your skincare routine, you know your skin's not optimized, you haven't quite figured it all out yet, you're still working on evening out your skin tone, getting that healthy lit-from-within glow, this would be a great way to get to that first level. So my final word and rating on this product is, is it the best overall superstar anti-aging product that you can add into your routine? Absolutely not. Is this a great co-star, an additional product, a booster that you can add alongside a nice fully developed skincare routine to boost your results? Maybe, especially if you haven't quite hit all of your skincare goals just yet. And so for that reason alone I'm going to be rating this a seven out of ten. Once you understand how to use this in your routine, it could actually be very helpful as a co-star to the rest of your skincare products."

"COSRX is calling this a serum booster, and the key word there is booster. It helps lift up the rest of your routine, but on its own, if it was your only active product, meaning the peptides in it, I think you might be disappointed with it. I personally was when I tested this out. I didn't feel that I got a ton of benefits from it on its own. I think it works well as a booster, but it's important to know this isn't a highly concentrated serum, this is an essence. COSRX is using some more interesting peptides, and I think the mix delivers a more unique set of benefits. [...] There are some collagen stimulating peptides in here, though it's not a heavy focus of the six peptide mix they're using. They're also looking to address signs of sensitivity and irritation on the skin, redness and inflammation, which can be particularly helpful if you have a sensitive skin type, if you're struggling with your moisture barrier, but it can also be helpful if you struggle with inflammatory acne as well. There's also a brightening peptide in here that can help with the overall complexion and clarity of the skin, the evenness of it."
