What the gurus are saying

Quick absorption and a silky, lightweight feel are what stand out about this peptide serum, and several takes praise how fast it sinks in. Several gurus say it helps firm and plump the skin, and it sits well alongside tretinoin or retinol. The one thing to keep in mind is scent, since one take calls it smelly, and a couple of gurus feel it is pricey and less impressive next to newer serums.

"Paula's Choice Pro-Collagen Multi-Peptide Booster is lovely. It's lightweight, fast-absorbing, and doesn't pill. I use it in the morning on top of my vitamin C and at night before my retinoids. [...] The whole line is great, but if I could only pick one product to use and to purchase, it would be this one, the serum. I find that serum is something I can use through my routine more regularly. These are great peptides, pro-collagen peptides that help to improve and support collagen production."

"If you're looking for a smooth, silky, lightweight serum, Paula's Choice Pro-Collagen Multi-Peptide Booster is really elegant. It contains eight different peptides that can help support collagen synthesis, along with glycerin, amino acids, and glutamic acid. Those are really wonderful humectants that plump and hydrate the skin."

"So this one's got peptides in there. It's got the Sinhiken peptide, which is claimed to boost the synthesis of hyaluronic acid deep down in the skin. It's got the Syncol peptide, which is supposed to boost collagen in the skin. It's also got the Syntax peptide, as well as other ingredients. It's really nice. I've repurchased this product a couple of times."

"If you're looking for some good peptides, Paula's Choice Pro-Collagen Multi-Peptide Booster is a little bit pricey, but it's got some really nice ingredients. It has a wonderful texture and lots of good peptides in it. It applies really easily, or you can mix it into a moisturizer or just apply it like a serum. It's wonderful, the texture is lovely, and it's great."

"It's very small, 20 mL, 0.67 ounces. It's not meant to be used as a serum per se. It's meant to be mixed in with another product, but to be honest, I didn't use it that way. I just applied a couple of drops and patted it on my face. I didn't mix it with anything. It's just too high maintenance for me. I like that it's fragrance-free. If this had copper peptides in it, I'd be all over it, because I can't get enough of my copper peptides lately. So, no issues with it. Decent product."

"The current one I've been finishing up that way is the Paula's Choice Pro-Collagen Multi-Peptide Booster. Actually, it's not a bad product. But compared to some of the newer things out there these days, I'm not as impressed with it as I was when it first came out. I have repurchased it several times, though, so there's that. After I'm done with all my face stuff, I'll put it on my neck and chest."

"I enjoyed this one. The bottle's small, although now I see it at TJ Maxx for about 10 bucks, so it might be worth it. I'd use this again if I had a backup. I'd probably start using it, or maybe this would be another good one to mix the copper peptides in. I don't know."

"It's been a while since I've used it, but I really enjoyed this serum when I was using it. I do believe there's a little bit of a scent to it, from what I can remember, because there's an ingredient in it called pyrus malus. I hope I'm saying that right. It's basically a fruit extract, and I remember when I was using that serum I could smell it, but it was very, very mild. There's no added fragrance to the serum, but I think I can remember there being a slight scent."

"I remember really liking this, and I do, and I still recommend it. It contains six procollagen peptides, which help to firm the skin and stimulate new collagen. It also has amino acids, as well as hyaluronic acid, so it's going to plump and hydrate and help maintain a healthy skin barrier. You can use this in the morning, and you can also use it at night, every day, twice a day. This was a serum I would pair up with tretinoin occasionally or retinol, and you can pair peptides with those."

"So this is from Paula's Choice, and this is the Pro-Collagen Multi-Peptide Booster. It has your peptides, but the formula is also quite hydrating, which is why this is one of my favorites to use with tretinoin. As you know, tretinoin can be a little drying on the skin and create that flakiness, so I like to keep my skin as hydrated as possible when I'm using products like this."

"Another great option for a regular peptide serum would be Paula's Choice Pro-Collagen Multi-Peptide Booster. There's no copper in this one, but this one contains multiple peptides, so you're getting more than one here. This one is also very lovely. It absorbs into the skin and gives your skin this nice plump look. But with consistency, your skin can appear firmer, and it just looks more youthful at the same time."

"This is Paula's Choice Pro-Collagen Multi-Peptide Booster. I actually never used this before. It's the first time I'm using it. It's kind of a medium-ish gel texture. It's not too heavy, and it's not really moisturizing, but I can definitely feel that there's a tiny bit of plumpness to it. It feels pretty good, so I can't tell you too much about it right now, unfortunately."
~Nay
"I'm trying so hard to use a serum I got from Paula's Choice, [...] the Peptide Booster. [...] It is so smelly."
~Yay
"Oh my goodness, it disappeared so fast. If you guys haven't tried Paula's Choice products before, they are absolutely incredible. They're taking scientific knowledge of skin care to the next level with some really, really great formulas. It also applied really quickly. I actually love how it looks on my skin, because my skin does not look shiny at all. It looks very even, and I love when products sink into the skin really quickly. This is definitely a win for me."
~Yay
"If your main issue is anti-aging, then on the day you've exfoliated, I'm happy for you to use the Pro-Collagen Multi-Peptide Booster to stimulate collagen. If your main issue is pigmentation, though, there aren't any serums from the brand that I would recommend wearing after you've exfoliated."
~Yay
"This brand is one of my favorite skincare brands because their products are just formulated so well. [...] You can see that this one has just a little bit of a thicker texture or consistency, but again it absorbs in really nicely and quickly and finishes very nice and smooth on the skin, so not much to say about that, which is what we want. [...] This is your treatment step. It's going to do your anti-aging, skin brightening, and skin barrier strengthening, and help your skin reset."

What the evidence says.

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

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

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.
