Azelaic acid calms redness, unblocks pores and fades marks at once, making it one of skincare's most underrated multitaskers.

Key takeaways

• Azelaic acid treats acne, rosacea-type redness and post-inflammatory dark marks all at the same time.
• It works by calming inflammation, thinning the plug inside pores and slowing excess pigment production.
• Over-the-counter versions sit around 10 percent, while prescription-strength formulas go up to 15 or 20 percent.
• It's gentle enough for sensitive and pregnant skin, which is rare for an active this effective.
