What the gurus are saying

Gurus praise the formula's stability and gentleness relative to typical ascorbic acid serums, with most reporting no irritation, oxidation, or skin discoloration over weeks of use. The peptide technology backed by clinical research on human volunteers resonates as a legitimate differentiator. The recurring complaint is the strong persistent orange-peel aroma that lingers on skin all day. One reviewer felt the vitamin C formulation itself could be optimized better, suggesting the peptide carries the appeal while the serum formula feels generic. Overall consensus is strong value for a beginner-friendly, irritation-free vitamin C option.

Best Vitamin C Serums of 2025- Dermatologist’s Top Picks
"The Neutrogena Collagen Bank has depeptide technology for collagen boosting. You have vitamin C which is 15% ascorbic acid and you got 2% gluconolactone or PHA which is a gentle exfoliant. So you're getting some exfoliative properties as well as brightening properties and some collagen boosting. I love this vitamin C serum so far and it's very affordable. It's great for beginners or for people who want to try out a higher percentage from the 10% ascorbic acid."
Overhyped Skincare Ingredients for Collagen Boosting- Dermatologist Reviews
"Neutrogena, they've done a pretty good job with theirs, too. Neutrogena specifically has also combined their peptides with their vitamin C."

"This was not a bad experience for me. Normally I find ascorbic acid serums burn, sting, and they get oxidized over time. They turn the skin kind of this orangey hue. They end up being really irritating for me. And I'd never experienced that with this. I finished the entire bottle, got no orange discoloration, didn't stain things. It does have that kind of toasty ascorbic acid serum aroma to it. The other thing about this collagen bank vitamin C serum and the entire collagen bank line that is underrated is the peptide in it, this teeny tiny peptide they spent 15 years developing. There is actually clinical evidence in a peer-reviewed paper that looks at the peptide applied to the skin of actual human volunteers documenting benefits and visible results as far as improving wrinkles and improving jaw contour and saggy skin."

*NEW* Neutrogena Collagen Bank Vitamin C Serum & SPF 30 Review
"For a vitamin C serum, this has not caused me any irritation. It has not caused me to have discolored orange skin. It hasn't changed color. I've been using it for several weeks now. Without a doubt, you can smell this on the skin. As with many ascorbic acid serums, they all for me when I wear them smell very similar to when you peel a bunch of oranges and you take a whiff of your fingers. That smell is lingering on your face all day while you're wearing this. It does not fade. It's like, did I smell orange juice all over my face? Yeah, it's that kind of aroma, which for some people you may not even notice. It may not bother you. I notice it. This is a product you want to apply in the morning, as vitamin C serums are recommended to be used."

*NEW* Neutrogena Collagen Bank Vitamin C Serum & SPF 30 Review
"My skin feels smooth and hydrated. I think this has helped cut down on irritation that I often experience with ascorbic acid serum. The ascorbic acid serum from them is compelling. If you are interested in a vitamin C serum or you find them to be beneficial in your skincare routine, this is a pretty good and affordable option. It's got some really good ingredients in it. It comes from a company that is very reputable, has massive R&D. They spent eight years on the peptide in this. They put a lot of research and development, not just cells in a dish, but on actual human volunteers testing their products. I've tested it out. It's been just fine for me. I think it is a really good affordable drugstore vitamin C serum with ascorbic acid with the potential to improve collagen production, hence the name collagen banking."

"The vitamin C, it's fine, but it's an ascorbic acid serum that I think could be formulated a little bit better in order to maximize the benefits you're going to get from that vitamin C. There's nothing in here that I think is groundbreaking. I think there are far better vitamin C serums out there. It feels like they've created something special in terms of that peptide and then just put any old formula alongside it. I want it a little bit better."
