Naturium Azelaic Acid Derivative Complex 10%

It is named for azelaic acid and contains none. Naturium quietly renamed it — effectively an admission.

A dermatologist’s take

Do Not Recommend.

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%.

Pros

  • No added fragrance
  • Good fit for sensitive skin

Cons

  • Uses an azelaic acid derivative
  • Azelaic acid treatment evidence does not directly transfer

Skin fit

Who is it best for?

Sensitive Skin on light skin.

Sensitive Skin

Good fit

Real azelaic acid stings most people for the first few weeks and plenty give up. The derivative here is water-soluble and does not sting, so it is the version reactive skin can actually wear.

Redness and fine superficial vessels across a light-skinned cheek and nose.

Rosacea

Okay fit

Rosacea skin flushes easily and rejects grit and rubbing, and this serum is smooth to use. But the strong rosacea evidence belongs to azelaic acid itself and does not transfer to a derivative.

Flat light-brown residual marks on a fair cheek.

Post-Inflammatory Hyperpigmentation

Okay fit

Niacinamide is fifth on this list, with its own good evidence for fading marks by blocking the handoff of pigment into surface cells.

It may be doing more of the work here than the ingredient on the front.

Flat tan patches with soft irregular edges across the forehead and upper cheek of an adult with light skin, the surface completely smooth.

Melasma

Poor fit

Real azelaic acid is a genuine melasma treatment, which is what this borrows its name from. The derivative is much milder; melasma usually needs azelaic acid at 15-20% or a prescription.

Adult cheek with a mixture of small red papules and a few tiny white-topped pustules; restrained common acne.

Inflammatory Acne

Poor fit

Azelaic acid has an antibacterial action; the derivative is too gentle to do much against red, sore spots. A calming layer, not a treatment.

comedonal acne on light skin.

Comedonal Acne

Poor fit

Blackheads need something that clears the plug, like a retinoid or salicylic acid.

Feel & smell

What does it feel like?

HeaviestLightest

Serum

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.

How this formula 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.

Full clinical explanation

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.

Full ingredient list · 18 ingredients

Water, Propanediol, Potassium Azeloyl Diglycinate, Polyacrylate Crosspolymer-6, Niacinamide, 3-O-Ethyl Ascorbic Acid, Caprylyl Glycol, Coffea Arabica Seed Extract, Sodium Hyaluronate, Phenylpropanol, Phenoxyethanol, Citric Acid, Potassium Chloride, Glycerin, Chlorphenesin, Tocopherol, Potassium Sorbate, Sodium Benzoate

All ingredient roles

Sodium Hyaluronate

A form of hyaluronic acid. Its molecule is large, so it stays on the surface and holds water there.

Glycerin

A small humectant. It moves into the outer layer of skin and holds water there.

Water

The base the other ingredients are dissolved in. Most of it evaporates soon after the product goes on.

Phenoxyethanol

The preservative. It stops bacteria and mold from growing in the product.

Tocopherol

Vitamin E, an antioxidant. Here it mainly keeps the oils in the product from going rancid.

Use & results

In your routine

How to use it.

01 / EVERY DAY

How much

A pea-sized amount on clean, dry skin, before moisturizer.

Careful

Patch test for a few days first. Wear sunscreen in the morning, since niacinamide and the vitamin C derivative are both working on pigment.

02 / OVER TIME

What to expect

Give it 8 to 12 weeks. This is a mild ingredient with thin evidence, so judge it on whether your skin looks calmer, not on what azelaic acid is known to do.

Price spectrum

Where does the price fall?

Paying more doesn’t guarantee better results. A good buy is a formula with the right ingredients, strength and texture for your skin. Use price per ounce to compare cost, then weigh it against the pros and cons above.

The product line

Which Naturium product should you choose?

Naturium’s lineup includes hydrating serums, peptide formulas and richer moisturizers. Some options mainly add a light hydration layer, while others provide a more substantial cream texture. Compare the ingredient approach and finish with what your routine is missing.
