Azelaic acid is a little-known cosmetic active ingredient. Naturally extracted from cereals (wheat, barley, rye), it has been used in medical dermatology since the 1980s - under prescription, at concentrations of 15-20 % - to treat rosacea, couperose and acne vulgaris. In cosmetology, available at around 10-15 %, it offers a unique profile: multi-target (blemishes, redness, imperfections, pores), low-irritation, and compatible with the most fragile skins.
ℹ️ Informative and educational article. In the case of diagnosed rosacea or moderate to severe acne, a dermatological consultation is recommended.
The biology of azelaic acid: six documented mechanisms of action
| Mechanism of action | Targeted issues | Observable time |
| Tyrosinase inhibition | Pigmentation spots, melasma, colored scars | 8-12 weeks |
| Anti-inflammatory action (5-lipoxygenase inhibition) | Redness, couperose, rosacea, inflammatory acne | 2-4 weeks |
| Antibacterial activity (C. acnes) | Acne, infected blemishes | 4-6 weeks |
| Normalization of keratinization | Blackheads, pores, skin texture | 4-8 weeks |
| Regulation of sebaceous production | Oily skin, shiny areas | 4-6 weeks |
| Gentle keratolytic activity | Texture, radiance, cell renewal | 4-8 weeks |
Science: A review published in the Journal of the American Academy of Dermatology lists the clinical evidence for azelaic acid: comparable efficacy to tretinoin 0.05 % on comedones and inflammatory papules, comparable efficacy to hydroquinone 4 % on pigmented spots, with better tolerability than these two references.
What sets azelaic acid apart from all other cosmetic exfoliants? normalizes keratinization without accelerating cell renewal. Unlike AHAs, which accelerate desquamation, azelaic acid acts on the maturity of keratinocytes so that they migrate normally towards the surface - without the irritation induced by forced desquamation.
Analysis by Dr Sylvain David: Azelaic acid is the active ingredient I first recommend to patients with rosacea or couperose who want to treat their spots and imperfections without aggravating their redness. It's one of the only active ingredients that acts simultaneously on vascular inflammation and pigmentation without irritating.
Azelaic acid vs AHA vs BHA: objective comparison
| Criteria | Azelaic acid | AHA (glycolic) | BHA (salicylic) |
| Skin irritation | Low | Moderate to high | Moderate |
| Photosensitization | No | Yes | Yes (moderate) |
| Anti-stain action | Yes (tyrosinase) | Indirect (renewal) | No |
| Antibacterial action | Yes (C. acnes) | No | Yes (indirect) |
| Anti-redness action | Yes (anti-inflammatory) | No | No |
| Rosacea / couperose | Yes - indicated | No - may aggravate | With care |
| Sensitive skin | Very well tolerated | Introduce with care | Introduce with care |
| Pregnancy | Compatible (consult your doctor) | Avoid | Avoid |
Conclusion: azelaic acid is the only one to combine direct anti-spot action (tyrosinase), anti-redness action and maximum tolerance. It is the active ingredient of choice for skin that cannot tolerate conventional exfoliants.

Product-by-product analysis
Nooance - Clarifying Anti-Redness Care 15 % AA + 2 % BHA
Yuka: 100/100 | Rating: 9.5/10
Que Choisir : A | Made in France | Fragrance-free
This is the most complete formula of the comparison. 15 % azelaic acid + 2 % salicylic acid (BHA) - the two active ingredients are complementary: AA acts on vascular inflammation and pigmentation, while BHA penetrates sebum-laden pores and exfoliates them from within.
Analysis by Dr Sylvain David: Nooance Clarifying Care is the formula I recommend for skin with both redness (incipient rosacea, couperose) and imperfections. The AA + BHA combination is particularly well thought-out.
Verdict: 9.5/10 The most complete formula of the comparison. AA + BHA = optimal synergy for combination to oily skin with redness and imperfections.
Geek & Gorgeous - Azid 15 % (azelaic acid + oats + carnosine + ceramides)
Note: 9/10 | Note : Price : ~14 € / 30 ml
15 % azelaic acid in a formula enriched with : colloidal oatmeal (anti-inflammatory, soothing), carnosine(antioxidant and anti-glycation dipeptide - glycation is the binding of a sugar to tissue proteins, a process that degrades collagen and elastin), ceramides (reconstitution of the skin barrier), EGCG (epigallocatechin gallate, a powerful antioxidant in green tea).
The milky texture is rare for an azelaic acid serum. Carnosine is an anti-aging active rarely found in mainstream cosmetics - its inclusion in this serum gives it an anti-aging dimension that other AA serums lack.
Verdict: 9/10 - The most complete formula in terms of complementary active ingredients. The only AA serum with anti-glycation carnosine.
Typology - Azelaic Acid Serum 10 % + Zinc + Bamboo
Note: 8,5/10 | Price : ~25 € / 30 ml | 97 % ingredients of natural origin
10 % azelaic acid + zinc (antibacterial, sebum-reducing) + bamboo (absorbs excess surface sebum), immediate mattifying effect from the first application). The concentration of 10 % is sufficient for cosmetic action, but corresponds to the lower limit of clinically documented efficacy.
Verdict: 8.5/10 Immediate mattifying effect thanks to bamboo. Concentration 10 % sufficient for prevention and maintenance.
Aroma-Zone - Azelaic Acid Concentrate Serum 10 %
Yuka: 100/100 | Rating: 8/10
Que Choisir : A | Price : ~8 € / 30 ml | Made in France
Purified formula, 10 % pure azelaic acid. 100/100 on Yuka. Very affordable price (~8 € / 30 ml). Ideal for discovering azelaic acid on a budget or to integrate it as a complement to an already-built routine.
Verdict: 8/10 - Best value for money. Pure formula with no additional active ingredients. Ideal for discovering the active ingredient or as a supplement.
Associations and compatibilities
Beneficial associations
- Azelaic acid + retinol: recommended combination. AA partially compensates for the irritation of retinol and amplifies the anti-spot action.
- Azelaic acid + niacinamide: direct synergy on spots (AA inhibits tyrosinase, niacinamide inhibits melanosome transfer - two different stages in melanogenesis).
- Azelaic acid + SPF 50+: any anti-spot treatment is enhanced by rigorous sun protection.
FAQ
Is azelaic acid suitable for rosacea?
Yes - that's precisely one of its dermatological indications. Finacea (azelaic acid 15 %) is a dermatological treatment for papulopustular rosacea. In cosmetology (10-15 %), AA reduces redness through its anti-inflammatory action on vascular dilation.
Is azelaic acid compatible with pregnancy?
Generally yes - it's one of the best-documented cosmetic active ingredients compatible during pregnancy. However, consult your doctor before use.
What's the difference between azelaic acid and glycolic acid?
Glycolic acid (AHA) accelerates desquamation - effective for cell renewal, but irritating and photosensitizing. Azelaic acid normalizes keratinization without accelerating desquamation - less irritating, non-photosensitizing, with the added benefit of direct anti-spot and anti-inflammatory action not found in AHAs.
Can azelaic acid be used in the morning?
Yes - unlike AHAs and BHAs, azelaic acid does not photosensitize. It can be applied in the morning. An SPF 50+ is still recommended in any anti-spot routine.
