Naturium Azelaic Acid Derivative Complex 10%: Dermatologist Review
Naturium Azelaic Acid Derivative Complex contains no azelaic acid. Its active is potassium azeloyl diglycinate, a different, water-soluble molecule, and azelaic acid's evidence for rosacea and breakouts does not transfer to it. Naturium renamed the product to say so, which was honest. If you want azelaic acid, buy it at a stated 10% or 15%.

The short versionWhat It Is
−
Naturium Azelaic Acid Derivative Complex 10% is a light, fragrance-free water serum for about $18 to $20, a gentle treatment for redness and uneven tone. It contains no azelaic acid, and Naturium renamed the product from Azelaic Topical Acid 10% to say so.
The active is potassium azeloyl diglycinate at 10 percent — azelaic acid joined to two glycine units, which makes it water-soluble and much milder. Niacinamide sits fifth, with a stable vitamin C derivative and sodium hyaluronate behind it. Nothing grips or grits, which is why it feels like water.

How it feelsTexture
−
Naturium Azelaic Acid Derivative Complex 10% is a thin, water-light serum that absorbs in seconds and leaves nothing behind.
No grit, no pilling, no white cast, no sting. That is the entire reason to choose it over a real azelaic acid product, and not a small thing if texture made you quit last time.
It is fragrance-free and sits under sunscreen and makeup without rolling up.

What's insideHow Naturium Azelaic Acid Derivative Complex 10% Works
−
Azelaic acid earned its reputation by doing three things: quieting the inflammation behind rosacea, killing acne bacteria, and blocking tyrosinase, the enzyme that makes melanin. Those findings were made with azelaic acid itself, at 15 or 20 percent.
This product contains a different molecule. Potassium azeloyl diglycinate is azelaic acid bonded to two glycine units, which makes it dissolve in water. That is why the serum is smooth and does not sting, and also why the parent ingredient's evidence does not carry across.
What the bottle does have is niacinamide, with solid evidence for barrier strength, oil control and pigment. If real azelaic acid defeated you on grit or stinging, this is a reasonable gentle alternative — just not the same ingredient, and the 10 percent refers to the derivative.

In the pore
In the skin barrier
Azelaic acid does three things at once: loosens the plug in the pore, reduces the bacteria in it, and calms the pigment cells that leave a dark mark behind. That combination makes it useful on deeper skin tones, where the mark often outlasts the spot.
The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.
The cells that make pigment. They sit along the base of the epidermis and hand melanin to the cells around them, which is what gives skin its color. Dark marks, melasma and the patch left behind by a spot are all these cells making more than usual.
A narrow tube running from the surface down into the skin, with an oil gland at the bottom of it. Oil travels up and out. When the tube blocks, what is behind it has nowhere to go — which is where blackheads and spots start.
Makes sebum, the oil that keeps the surface soft and stops water escaping. How much it makes is set by hormones, not by how often you wash — which is why scrubbing does not fix oily skin.
Cutibacterium acnes lives in the pores of everyone with skin. It is not an infection and it is not a hygiene problem. It only causes trouble when a pore blocks and it multiplies in the oil trapped behind it.
The scaffolding in the dermis that keeps skin firm and springy. It is built by fibroblasts and broken down by age, sun and smoking. Lines and looseness are collagen lost faster than it is replaced.
The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.
Pulls water into the surface and holds it there.
A light oil close to the kind skin makes. Fills the gaps between cells.
Calms and softens. It is why an oat cleanser feels different.
The outermost layer, and the one every moisturizer is aiming at. It is dead — flattened cells stacked like bricks, with a mix of fats as the glue between them. That glue is what holds water in and keeps irritants out.

The fine printA Dermatologist’s Concerns
−
It contains no azelaic acid: there is no azelaic acid in this product.
The evidence does not carry over: the active is potassium azeloyl diglycinate, a derivative. Different molecule, and you cannot transfer azelaic acid's evidence to it. That Cochrane review grading azelaic acid as high-quality evidence for rosacea does not apply here.
The derivative is barely studied: the few studies that exist tested it combined with other actives, so its independent effect cannot be separated out.
The old name misled buyers: it used to be "Azelaic Topical Acid 10%," and it is now "Azelaic Acid Derivative Complex 10%." That change is an admission, and to their credit they made it. But a great many people bought this thinking they were buying azelaic acid.
The 10% is not azelaic acid: the "10%" refers to the derivative.
It costs more than the real thing: $20 for a derivative, when $12 buys the real thing.
What it runsPrice per Ounce
−
Naturium Azelaic Acid Derivative Complex 10% costs $20 per ounce. That is cheaper than 2 of the other 5 exfoliants priced on Dermapedia, which run from $9.27 to $42 per ounce.
Price per ounce is a fair way to compare value, but not the whole story — a thicker product goes further per application, and an expensive active costs what it costs.
