Azelaic Acid

Product Description

Azelaic Acid is a dermo-cosmetic gold standard, celebrated for its unique, multi-pathway approach to skin health. It is one of the few ingredients scientifically proven to simultaneously target the three most common skin concerns: acne, inflammation, and hyperpigmentation. Its key advantage is its "gentle-yet-powerful" profile, making it a preferred choice over other harsh actives. It regulates keratinization, reduces blemishes, calms the redness associated with rosacea, and fades post-acne marks. For formulators developing high-performance, "all-in-one" solutions, Azelaic Acid is an indispensable, clinically-backed active.

Product Uses

This multi-functional active is a cornerstone for a wide range of dermo-cosmetic formulations:

• Problem Skin: The ideal hero ingredient for anti-acne treatments, oil-control serums, and blemish-clearing lotions.
• Soothing Formulations: A key component in creams and gels for sensitive skin, especially those targeting redness and rosacea.
• Brightening Products: Used in spot correctors and brightening serums to reduce hyperpigmentation and fade post-inflammatory hyperpigmentation (PIH).

Formulation Suggestions

The typical dosage is between 5-20%. Formulating with Azelaic Acid presents a significant challenge due to its poor solubility. It can be formulated as a suspension, often in silicone or ester bases, though this may compromise texture. To create a homogenous solution, it must be dissolved in the glycol phase (e.g., propanediol) at high concentrations, often requiring heat (60-75°C). Micronized grades can improve the texture of suspensions. Achieving an elegant, non-gritty emulsion is the primary technical hurdle.

Our advice is for reference only. Please follow the recommendations of your formulator for actual production.
