The Inkey List Retinol is one of the gentlest retinol serums I’ve ever tried.
Weird, when you think it contains 2 forms of retinoids. And that some sources report retinol is here in a staggering 1% concentration (that’s super high for retinol, FYI).
If the rumours are true, this serum should be harsh and drying on the skin… but it ain’t. Something doesn’t add up here. Is it technological magic or marketing hype?
I’ve put it to the test to find out:
What’s In The Inkey List Retinol?
RETINOL TO FIGHT PREMATURE AGING
You’ve probably heard that The Inkey List Retinol contains 1% stable retinol. Wrong. It contains 1% RetiStar, a stabilised retinol compound. There’s a huge difference.
According to BASF (the maker of RetiStar), 1% RetiStar contains 0.05% retinol mixed with tocopherol, sodium ascorbate, and PEG-40 hydrogenated castor oil in caprylic/capric triglycerides.
1% retinol is a huge dose that has some serious wrinkle-fighting properties. 0.05% retinol is a tiny dose that’s suitable for beginners. It’ll help your skin a little, but it pales in comparison to what 1% can do.
See how easy it is to make you think a serum contains more retinol – and is therefore more powerful – than it actually is?
Even so, 0.05% retinol isn’t completely useless. In fact, retinol is so harsh, you absolutely need to start with a very small concentration and work your way up to 1%.
Starting with the higher dose straight away is a recipe to disaster that only leads to dryness and irritation. All things that make wrinkles look worse, not better!
So, what does retinol do?
- It has antioxidant properties that destroy the free radicals that cause premature wrinkles and dark spots.
- It accelerates cellular turnover (i.e. the skin’s natural exfoliating process), reducing the appearance of dark spots, wrinkles, and acne.
- It boosts the production of collagen, the protein that keeps skin firm.
It does this even at tiny concentrations – but do work your way up as soon as your skin can take it.
GRANACTIVE RETINOID TO FIGHT WRINKLES AND ACNE
Retinol isn’t the only retinoid in The Inkey List Retinol. This baby also contains 0.5% Granactive Retinoid (a.k.a. Hydroxypinacolone Retinoate).
Again, beware! Brands want you to think Granactive Retinoid is even more effective than retinol at fighting wrinkles and acne. It simply isn’t true.
There’s NO proof (yet) that Granactive Retinoid is more effective than retinol. Heck, there isn’t even much proof that it can fight wrinkles!
That’s because this retinoid is so new, there isn’t much research on it, yet. The only things we know for sure are:
- It’s gentler than retinol
- It’s effective at treating acne
Future research may show that Granactive Retinoid is a valid alternative for fighting wrinkles as well. Until then, I recommend it only to women with sensitive, acne-prone skin that can’t tolerate retinol.

PEPTIDES TO BOOST COLLAGEN
Peptides are the anomaly in the skincare matrix. In theory, they shouldn’t work: they’re too big to penetrate skin. In practice, studies show they do something.
One theory is they work even when left on the surface of the skin, by sending signals to skin cells to boost collagen production, ect. This serum contains two peptides:
- Palmitoyl Tetrapeptide-7: Part of Matrixyl 3000, it helps strengthen the skin’s protective barrier and soothe sensitive skin.
- Palmitoyl Tripeptide-1: Part of Matrixyl 3000, it helps stimulate the production of collagen and firm skin.
Again, most of the studies on peptides come from the manufacturers. I don’t recommend buying a serum just because it contains peptides. But if they’re an extra (like here), why not give them a go?
GLYCERIN, SQUALANE, & HYALURONIC ACID TO MOISTURISE SKIN
The Inkey List Retinol doesn’t only help prevent premature aging. It hydrates skin too. Here’s how:
- Glycerin: A moisture magnet that attracts water from the environment and binds it into the skin, helping to keep it hydrated.
- Squalane: Very similar to human sebum, it strengthens the skin’s protective barrier and moisturises skin.
- Hyaluronic Acid: Like glycerin, it attracts and binds water to the skin. It’s so good, it can hold up to 1000 times its weight in water!
Together, the extra moisture keeps your skin softer and smoother. It also helps prevents dryness, a common side effect of retinol.
Lightweight, yellow gel. It sinks in quickly without leaving a tacky residue behind.
How To Use It
Three nights a week, after cleansing. Don’t exfoliate on the nights you use this!
Performance & Personal Opinion
I use The Inkey List Retinol every other night, alternating it with exfoliation. I don’t like to mix the two together because they can often irritate skin or dry it out too much.
Its texture sinks smoothly into my skin, leaving no tacky residue behind. It layers well with moisturisers, too – no pilling here.
It’s definitely gentle and a little more hydrating than most retinol serums I’ve tried. If you have sensitive skin or are looking for your first retinol serum, this is gentle enough for you (if your skin can’t take this, retinoids are NOT for you).
Does it work? It does help to improve the texture of your skin, making it smoother and brighter. It can also help you fade dark spots a little.
I admit I didn’t see much of a difference – but that’s because I’m used to 1% retinol. Compared to that, this just doesn’t work as well.
But you can’t use 1% straight away. It’ll dry out your skin, irritate it, and make it flake. And then you’re wondering why your wrinkles look so much worse when the exact opposite was supposed to happen. Take it slowly, ladies!
Who Is This For?
- First time retinol users who need a gentle serum to get started
- Sensitive, acne-prone skin that can’t tolerate retinol
- Skincare newbies who want to try both retinol and peptides for the first time
Who Is This Not For?
- If you’re already using a serum with a concentration retinol higher than 0.05%, this would be a step back.
White, opaque squeeze tube. It’s sleek, practical, and protects the retinol inside from light, air, and anything that could spoil it.
