What is a common effect of using Azelaic acid on the skin?

Azelaic acid is known for its anti-inflammatory properties, which can significantly contribute to the reduction of redness in the skin. It works by inhibiting the production of inflammatory markers and calming irritated skin, making it particularly effective for conditions such as rosacea and acne. The formulation not only helps to soothe the skin but also aids in reducing the appearance of redness associated with these conditions.

While the other effects listed may have some merit in different contexts or with different products, they are not primary or well-documented outcomes specifically associated with azelaic acid. For instance, while increased moisture retention and enhanced skin elasticity may be more relevant for other ingredients like hyaluronic acid or certain peptides, they are not characteristic effects of azelaic acid. Similarly, while azelaic acid can contribute to reduced oiliness, its more pronounced and recognized benefit lies in its ability to alleviate skin redness. Thus, the focus on azelaic acid’s effectiveness in reducing redness highlights its primary action and the reason why this choice is the correct one.
