Azelaic acid is unusually versatile for a single ingredient. It inhibits tyrosinase, the enzyme that makes pigment, so it fades dark marks. It also calms inflammation, which helps redness and rosacea; reduces acne-causing bacteria; and helps unclog pores.
That combination makes it a rare fit for skin that has redness and breakouts and the brown marks left behind by both. It is generally well tolerated, though tingling in the first few weeks is common and usually settles.
Prescription strength is 15–20%, and this 10% is the standard over-the-counter dose with reasonable supporting evidence. If you have genuine, stubborn rosacea or melasma, a prescription version will do more, and it is worth asking a dermatologist about.

Azelaic acid does four things at once, which is genuinely unusual:
Inhibits tyrosinase, the enzyme that makes pigment — so it fades dark marks Kills acne bacteria Calms inflammation — which is why it works for rosacea Unclogs pores
That combination makes it a rare single ingredient for skin that has redness and breakouts and the brown marks left behind by both.
Prescription strength is 15–20%, and 10% is the standard over-the-counter dose with reasonable supporting evidence.
It stings and tingles, especially the first few weeks. Normal, and it usually settles. Start every other day.
10% is weaker than prescription. If you have real rosacea or stubborn melasma, prescription azelaic acid at 15–20% will do considerably more, and it is worth asking about.
It is slow. Give it 8–12 weeks before judging.
Marketed as "Redness Relief," which undersells its value for pigmentation — worth knowing if you came looking for a dark-spot product.

Treatment of Acne in Pregnancy (Journal of the American Board of Family Medicine) (https://www.jabfm.org/content/29/2/254) — Supports the pregnancy-safety claim: topical azelaic acid is recommended as baseline acne therapy in pregnancy, while oral/retinoid therapy is teratogenic and absolutely contraindicated. 4.
