Review: The Inkey List Peptide Moisturizer

My review and test of the firming and hydrating Peptide Moisturizer from the British brand The Inkey List.

Once again, The Inkey List is trending with its new peptide moisturizer, the Peptide Moisturizer!

Indeed, the British skincare brand often releases products that meet the latest ingredient trends! (I already mentioned their concept in my review of their Multi-Biotic moisturizer.)

However, peptides are not exactly newcomers to cosmetics. They have been added to skincare formulas for years, but until recently, they were rarely spoken of.

And then, in the last few years, marketing caught on to them and products with peptides have been on the rise!

I’ve already mentioned them in several of my posts, peptides are tiny molecules made up of amino acids, which are protein precursors, and act on the skin as a trigger to provoke specific reactions.

Basically, they can mimic the signals from the brain sent to the epidermis via natural peptides. For example, some of them signal the skin to regenerate itself, or to stimulate the production of collagen and elastin; others will influence hydration, for example…

There are many different types of peptides! Generally speaking, however, they are expensive ingredients, but they have the characteristic of being effective at tiny concentrations. No need to use tons of them, which explains why they are often found at the very end of ingredient lists!

In this Peptide Moisturizer cream from The Inkey List, we’ll see that peptides are really the star ingredients of the product! Let’s take a closer look at this product.

The Inkey List Peptide Moisturizer, my thoughts:

When I saw this Peptide Moisturizer cream from The Inkey List in Cult Beauty’s new releases section a few months ago, I thought it reminded me of something… Not only with the formula, but with the packaging as well.

Indeed, many compare this product to Drunk Elephant Protini moisturizer, which I reviewed here almost 2 years ago.

So clearly, the concept is quite similar: in both cases, it’s a moisturizing cream that contains peptides. But let’s be clear from the start, this The Inkey list moisturizer is not really a dupe for Protini. Protini’s formula is more complex (and consequently more complete) than The Inkey List cream.

The Inkey List Peptide Moisturizer contains only 5 key skincare ingredients:
– two moisturizing ingredients: glycerin and betaine,
– a nourishing ingredient: shea butter,
– and two anti-aging and repair peptides: Acetyl Hexapeptide-37, Pentapeptide-48.

The stars of the formula here are the two peptides:
2% royal epigenetic peptide (Pentapeptide-48): provides a nourishing effect to help reduce the appearance of fine lines and wrinkles,
1% hexapeptide solution (Acetyl Hexapeptide-37): provides a moisturizing and stimulating effect on collagen production.

The brand highlights them to claim a firming effect, but clearly, if you look at their properties more closely, these two peptides are more about hydration and moisture!

In short, considering the formula, The Inkey List Peptide Moisturizer is a relatively basic moisturizing and nourishing product.

But it’s not necessarily a bad thing! Especially if you have a great routine with lots of other products rich in active ingredients and/or have a sensitive skin, simplicity in a product is great! 😉

But don’t expect miracles with this product, especially on anti-aging! Just to be clear. Even if the brand claims effects on firmness, I don’t really believe in it, especially in the short term. For me, this product is great to pair with other stronger treatments, like retinol or acids for example, but it definitely won’t be the star of the show in your anti-aging program.

And if I’m being picky, I would have appreciated at least one antioxidant ingredient in the formula 😜.

I’ve been using The Inkey List Peptide Moisturizer for just over 2 months now. I apply it in the morning (but it can be used in the morning and/or evening).

I’m a big fan of its super smart packaging: a closed jar, with just a small opening that delivers the right amount of cream by simply pressing on the top of the jar. Much more hygienic than all the classic jars with their formulas that are exposed to air and bacteria every day when you use them!

The texture is quite rich, but it doesn’t leave me my skin feeling greasy at all; it absorbs quite quickly but leaves my skin comfortable all day long!

Well, clearly, right now in Dubai temperatures are peaking at 46 degrees with 80% humidity, so the texture is a bit too much for me and my combination skin. I’ll probably have to switch to a super light gel moisturizer like I usually do this time of year! But so far, this Inkey list cream has done a splendid job for me!

In conclusion:

In short, it’s not necessarily the most exciting moisturizing cream formula I’ve seen, but it’s still an excellent product, simple and effective. Also, big plus, it doesn’t cost an arm & a leg, and it comes in a super practical packaging, too!

The Inkey List Peptide Moisturizer retails around $15 for 50ml.

  1. Glad to read this about the Inkey List Peptide moisturiser. I’ve been planning to try it since it was launched and have finally ordered it together with the Oat cleansing balm. It sounds as though it will suit my needs very well. I have mature, often dehydrated skin, prone to some small dry areas in cold weather. I already use a strong Vitamin C serum (Medik8 C30 Intense) and Retinal (just started Crystal Retinal 20 after using CR10 and r-Retinoate Intense for a couple of years). I also use a range of acids, so I don’t need my moisturiser to do much other than, well, moisturise. Sounds as if this product will fit the bill perfectly. Thank you for your thorough review.
