The Inkey List Collagen Booster, Review

The Inkey List Collagen Booster Review

a series of The Inkey List reviews continue


Over the past few months, I have been testing a lot from the Inkey List, which led to the creation of new series on this website. Last week we chatted about the brand’s award-winning Oat Cleansing Balm (review here), and today we will focus on their alluring Collagen Booster. Does it do live up to its claims?

About the Product

The Inkey List Collagen Booster Firming Peptide Serum (10.99 USD; Made in Canada) – is described as an anti-aging, firming serum that tackles fine lines and wrinkles for firmer, plumper skin.

Packaging: similar to all of the brand’s serums, this one too comes in a rather petite black and white recyclable plastic packaging, containing 30 ml/ 1.0 oz of product. The cap has a press button on it, ensuring tight closure and proper storage of the serum.

Formula: the key players here are Matrixyl 3000 (supports natural collagen production) and Syn-Tacks (a dual peptide that boosts collagen). You also get Hyaluronic Acid, Glycerin, and Radish Root Extract, all known for their hydrating properties.


Texture: the texture of Collagen Booster is quite similar to the brand’s Hyaluronic Acid, in a way that it is clear and liquidy. It feels watery and gets absorbed relatively quickly once it gets in contact with the skin, leaving no tacky residue or film behind.

Application: the Inkey List labeled this serum as a “targeted treatment” which means it should ideally go between your toner and moisturizer. It can be easily sandwiched somewhere in the middle, given how lightweight it is. I use about a penny-sized amount, which is more than enough to cover both face and neck. I then give it a moment to dry down and follow up with Hyaluronic Acid or any other serum I have at hand.

application tips

Collagen Booster can be used both during your AM and PM routines. It can also be mixed with your moisturizer or body lotions. Please do not go overboard with the amount of serum you use, as it might eventually ball up. Make sure to apply it to damp skin (use a toner or a mist) and layer a reasonable amount of moisturizer on top to lock in the moisture.

Immediate Results: skin feels refreshed; hydration levels are replenished. This sensation usually lasts well throughout the day.

Long-term Results: there is little to no dry texture or flaky skin. Although I can’t say much about lines and wrinkles (due to my age, I do not have any yet), I think that serum like this could be an excellent preventative method to avoid skin dehydration and premature aging. Hydration is definitely where this product shines. Skin is smooth, radiant.


I genuinely enjoy using Collagen Booster as part of my daily skincare regimen. An intuitive little formula absorbs and behaves well when following the correct application method. For moisturizing purposes, it is excellent, and given its weightless consistency and feel, I think this serum should work well for all skin types. The Inkey List products are well-formulated and budget-friendly, so if you are on a hunt for something to boost your skin’s moisture levels, look this way. B+ from me.
