Yet it solves many skin problems: acne, redness, spots, blackheads, texture. Its mechanisms are not all fully understood, but we do know that it \u00abbrings order\u00bb to cells that have become uncontrollable, whether they produce too much pigment (melasma) or over-react to inflammation (acne, rosacea).

In fact, this is what led to its discovery.<\/p><div class=\"bd-dark-quote\"><strong>White spots that put us on the trail<\/strong><p>In the late 70s, doctors noticed that a yeast, Malassezia furfur, was creating white spots by destroying pigments in the areas where it was spreading. They realized that it produced azelaic acid, studied it and discovered its impressive depigmenting properties. Since then, interest in this active ingredient has grown steadily.<\/p><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Formulation<\/span><h2>Concentration and <em>formulation<\/em><\/h2><p class=\"bd-lead\">Products with 10 % azelaic acid are readily available, but the formulation is complex: it comes in powder form, which is difficult to formulate at high concentration. This has two consequences. Firstly, products tend to lint (part of the powder remains on the surface after absorption); the intensity depends on the formulation. Secondly, like all powder ingredients, it matifies the skin after application.<\/p><div class=\"bd-alert bd-alert-info\"><span class=\"bd-alert-icon\">\u26a0<\/span><div>As is often the case, the higher the concentration, the more frequent the side-effects: mainly burning, tingling and itching. On healthy skin, the risk is low; in the case of sensitive skin, it's best to introduce azelaic acid gradually.<\/div><\/div><p class=\"bd-lead\">Antioxidant, anti-inflammatory, anti-spot, anti-redness, unifying, pore-enhancing: why is such an active ingredient still so rare in cosmetics? No clear answer. Perhaps because it's difficult to formulate, or because marketing relies on \u00abbest-selling\u00bb actives like hyaluronic acid, or simply because its multiple benefits remain unknown - a question that deserves to be put to the marquess that don't offer it.<\/p><\/div><\/section><!-- ===== S\u00c9LECTION PRODUITS ===== --><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">The selection<\/span><h2>Which products to <em>azelaic acid<\/em> ?<\/h2><p class=\"bd-lead\">Here are three representative azelaic acid products, with BeautyDecoded scores and user feedback.

When keratinocyte proliferation gets out of control, it creates hyperkeratinization: dull complexion, accumulation of dead cells, altered pores and blackheads. Rather than a brutal exfoliation (glycolic or lactic acid), azelaic acid forces cells to regulate their development and diminishes hyperkeratinization. Dead cells accumulate less in pores, improving their appearance and reducing the appearance of pimples.<\/p><\/div><\/section><!-- ===== CTA APP (bd-final standard) ===== --><section class=\"bd-final\" style=\"padding-top:48px !important;margin-top:0 !important\"><div class=\"bd-wrap\"><div class=\"bd-final-inner\"><div class=\"bd-section-label\">Further information<\/div><h2>Find the right azelaic acid for <em>your skin profile<\/em>.<\/h2><p>The BeautyDecoded application lets you scan any cosmetic product to visualize its suitability for your skin type and needs, based on INCI analysis.<\/p><div class=\"bd-cta-wrap\" style=\"justify-content: center;\"><a href=\"https:\/\/beautydecoded.go.link\/88eZ2\" class=\"bd-cta\" target=\"_blank\" rel=\"noopener\">Discover BeautyDecoded<\/a><\/div><div class=\"bd-cta-meta\" style=\"margin-top: 16px;\">Application available on iOS and Android<\/div><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Frequently asked questions<\/span><h2>Your questions about <em>azelaic acid<\/em><\/h2><div class=\"bd-faq-list\"><details class=\"bd-faq-item\"><summary>Is azelaic acid effective against acne?<\/summary><div class=\"bd-faq-answer\">Yes: it is antibacterial (against acne bacteria), anti-inflammatory, regulates keratinocytes and reduces the hyperkeratinization responsible for blackheads. It's an excellent anti-acne active ingredient, better tolerated than many others, even by sensitive skin.<\/div><\/details><details class=\"bd-faq-item\"><summary>Does azelaic acid lint the skin?<\/summary><div class=\"bd-faq-answer\">Some products do, because azelaic acid is a powder, some of which remains on the surface after absorption. The intensity depends on the formulation. Applying a thin layer and allowing it to absorb well before the next treatment limits the phenomenon.<\/div><\/details><details class=\"bd-faq-item\"><summary>Suitable for sensitive skin and rosacea?<\/summary><div class=\"bd-faq-answer\">Yes, that's one of its great assets: anti-inflammatory and antioxidant, it's appreciated by skin prone to redness and rosacea. However, it should be introduced gradually for very sensitive skin, as slight tingling may occur at first.<\/div><\/details><details class=\"bd-faq-item\"><summary>Can azelaic acid and retinol be combined?<\/summary><div class=\"bd-faq-answer\">Yes, it's even an excellent combination: the two act on hyperkeratosis in a complementary way, and azelaic acid, which is anti-inflammatory, helps to better tolerate the irritation of retinol.<\/div><\/details><details class=\"bd-faq-item\"><summary>At what concentration should it be used?<\/summary><div class=\"bd-faq-answer\">Cosmetic products generally range between 10 and 15 %.
