Paula's Choice 10% Azelaic Acid: Dermatologist’s Review

Azelaic acid has gained attention in recent years for its versatility in treating common skin conditions like acne, rosacea, and dark spots. One popular product in this category is the Paula's Choice 10% Azelaic Acid Booster. As a dermatologist, I often get asked if this product is worth trying. In this post, I’ll explain what azelaic acid is, how it works, and whether Paula’s Choice’s version is a good option for your skincare routine.

What Is Azelaic Acid?

Azelaic acid is a naturally occurring dicarboxylic acid derived from grains. It’s widely used in skincare for its:

• Anti-Inflammatory Properties: Calms redness and irritation.

• Antibacterial Effects: Targets acne-causing bacteria.

• Skin Brightening: Reduces hyperpigmentation by slowing melanin production.

• Gentle Exfoliation: Promotes cell turnover to smooth texture.

It’s often recommended for sensitive or rosacea-prone skin due to its mild nature compared to stronger acids.

Azelaic Acid Spectrum

Azelaic acid comes in different strengths, and choosing the right one depends on your skin and what you're treating. Here’s a quick look at common percentages:

• 5%: Ideal for beginners or those with sensitive skin.

• 10%: This is a common concentration in products like Paula's Choice and The Ordinary. It provides good results for acne, redness, and hyperpigmentation.

• 15-20%: These higher concentrations are usually prescription-strength and recommended for more severe acne or rosacea.

If you’re unsure which concentration to start with, consult a dermatologist for guidance.
