Question: 1 / 400

What is one of the primary functions of azelaic acid?

Reduces redness and irritation

Increases moisture retention

Promotes cell turnover

One of the primary functions of azelaic acid is to promote cell turnover. This ingredient is known for its ability to facilitate the shedding of dead skin cells, thereby helping to prevent clogged pores and reduce the appearance of blemishes. By promoting cell turnover, azelaic acid encourages the production of new skin cells, leading to a smoother, more even skin texture. This process is particularly beneficial for individuals dealing with acne or concerns related to hyperpigmentation, as it can improve the skin's overall appearance and promote a clearer complexion.

While reducing redness and irritation is a characteristic of azelaic acid, its more significant role lies in enhancing the skin's cellular activity. Other options such as increasing moisture retention or acting as a sunblock are not primary functions associated with azelaic acid, as it does not directly provide moisture or sun protection.
