    "I'm using the collagen peptide one from The INKEY List. I like [...] to put the serum on my eyelids to help expel [...] that fluid [...] that has built up. [...] You can literally feel the fluid in [...] your eyelids moving. I [...] don't want to be tugging on my skin too hard, which is why I want the serum so I can just go back and forth really slowly."

    "Some Collagen Peptide Serum could save the day. The Collagen Peptide Serum from the Inkey List does not label itself as a hyaluronic acid serum but it does have hyaluronic acid in it and when you actually look at it, it is extremely plumping, helps to support the skin barrier, helps to nourish the skin, grabs hydration and pulls it into the skin because of the peptides and collagen in here. [...] Collagen and peptide sides are humectants and they can draw moisture into the skin for 72 hours."

    All 6 takes from The Budget Dermatologist
    Anti-aging Routine on a BUDGET! | The Budget Dermatologist
    "I recommend this one, the Collagen Peptide Serum. There is so much evidence and benefits of peptides in skin care, and this product specifically has the peptide in it called Matrixyl 3000, and that is one of the most studied types of peptides that shows anti-aging benefits. This one is only $12.99. Peptide skin care can build new collagen, so don't layer this at night."
    Peptide Skincare for Anti-aging | The Budget Dermatologist Explains
    "It's the Collagen Peptide Serum by The INKEY List. This one is $12.99, so it's very affordable. It has Matrix cell 3000 as well as a dual blend of pomatoil dipeptide 5 types. [...] This is just a great product and it's very easy to incorporate into your morning or nighttime routine directly after cleansing your skin. I love this one."
    My Peptide Skincare Routine | Anti-aging Tips by The Budget Derm
    "I like to specifically go for products that have Matrix L 3000 as the form of peptide in it because I think that this complex of peptides has more support for building new collagen in the skin. The Inkey List's collagen building product is one of the lowest price peptide serums that has the Matrix L 3000 complex in it that I've tried, at $112.99. I've mentioned this on my channel before and it is a great option if you're looking for something really affordable."

    "Another one I love is The INKEY List Collagen Peptide Serum. This is way more affordable and it's actually really good. It can be a workhorse serum, peptide serum in your routine. It has Matrixyl C 3000 in it, which is the most recommended and studied type of peptide for anti-aging."
    The BEST Anti-aging Ingredient Since Retinoids! | The Budget Dermatologist
    "Starting with my top budget pick by The INKEY List, it's the Collagen Peptide Serum. This contains Matrixyl 3000. Now if you can only get one category of peptides, one of the four that I mentioned earlier, go with Matrixyl 3000, which is what is in this. So you can always start simple and start here."

    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.
