Yes. Azelaic acid is one of the few pigment ingredients that has been studied directly on darker skin. In a 24-week trial on people with darker skin, a 20 percent cream reduced the intensity of facial dark patches more than a plain cream did. Expect some stinging early on. The strengths that were tested are prescription products.
What azelaic acid is
Azelaic acid is a naturally occurring acid. DermNet describes it as a by-product of Malassezia furfur, a yeast. Doctors prescribe it mainly for acne and rosacea, as a cream, gel or foam.
It earned its place in dark-spot care for a second reason. DermNet says it also helps reduce pigmentation, and calls it particularly useful for darker-skinned people whose acne spots leave persistent brown marks. The same page says it does not change the color of normal skin, which matters if your goal is even tone and not a lighter shade.
IYASA does not make an azelaic acid product. If you want a daily moisturizer that works toward the same goal, our Brightening Cream uses niacinamide and vitamin C.
What the studies on darker skin found
Two trials from 1998 are still the ones most often cited, and both enrolled only darker-skinned patients.
- Azelaic acid against a plain cream. Lowe and colleagues ran a randomized, double-masked trial of 20 percent azelaic acid cream in patients with phototypes IV to VI, the brown-to-deep range. The trial ran for 24 weeks. Azelaic acid lowered pigment intensity more than the plain cream, both by the investigators' scoring and by instrument readings. It also caused slightly more burning and stinging.
- Azelaic acid against hydroquinone. Kakita and Lowe compared 20 percent azelaic acid cream plus a glycolic acid lotion with 4 percent hydroquinone cream, again over 24 weeks. Overall improvement was comparable in the two groups. The azelaic and glycolic group had slightly more peeling, burning, stinging and dryness, though the scores stayed low.
Two cautions. These trials are old, and both used prescription strength. They do not tell you what a low-strength cosmetic serum will do.
Strengths and how you get them
| Form | What it is | How you get it in the US |
|---|---|---|
| 20% cream | The strength used in the dark-skin trials; prescribed for acne | Prescription |
| 15% gel or foam | Prescribed for rosacea | Prescription |
| Lower-strength serums and creams | Cosmetic products | No prescription needed |
The AAD includes azelaic acid in its list of ingredients to look for in a product you can buy without a prescription for dark spots on darker skin tones. So the over-the-counter route is a recognized one. The evidence is just stronger for the prescription strengths.
Side effects, and why they matter more on dark skin
MedlinePlus lists itching, burning, stinging, tingling, tenderness and dryness as the common ones. On melanin-rich skin, irritation is more than a comfort issue, because an irritated patch can leave its own dark mark. Our guide to acne marks on dark skin explains that cycle.
To keep it calm:
- Patch test on a small area for about a week before using it on your face.
- Start every other night, on dry skin, and move to nightly once the stinging settles.
- Follow with a plain moisturizer.
- Do not add another acid or a scrub on the same night.
- Wear a separate sunscreen every morning.
- If you are pregnant or breastfeeding, ask your doctor first.
How it compares with other options
Hydroquinone is a prescription drug with a longer list of concerns; see alpha arbutin vs hydroquinone for where it stands. Kojic acid is usually used in a wash-off soap. Niacinamide and vitamin C are the gentle daily options, and our niacinamide guide covers the first of them. Which mark you have also matters: post-acne marks, sun spots and melasma do not all respond the same way.
What IYASA sells, and what it does not
We do not sell azelaic acid, and if your doctor has prescribed it, use theirs as directed. What we make sits beside it. The Brightening Cream is a water-based moisturizer with 10% niacinamide and 5% vitamin C that helps even the look of skin tone on face and body. Used in the morning, with azelaic acid at night, the two do not compete. Add one product at a time, a few weeks apart, so you can tell what your skin is reacting to.
Frequently asked questions
Is azelaic acid good for Black skin?
It is one of the better-studied options. Two trials on darker-skinned patients found that a 20 percent cream reduced facial dark patches, with some burning and stinging as the main complaint.
Can azelaic acid make hyperpigmentation worse?
The ingredient itself works against excess pigment, but it can sting and burn in the first weeks. On dark skin, irritation can leave new marks, so start slowly and stop if your skin stays irritated.
How long does azelaic acid take to work on dark marks?
Think in months. The two main trials on darker skin both ran for 24 weeks.
Do I need a prescription for azelaic acid?
In the US the 15 and 20 percent products are prescription medicines. Lower-strength cosmetic products are sold without one.
Does IYASA make an azelaic acid product?
No. Our Brightening Cream uses 10% niacinamide and 5% vitamin C, and it can be used in the same routine as an azelaic acid product.
