Azelaic acid, quietly.
The active that does three jobs at once and rarely gets top billing. Anti-inflammatory, anti-pigmentation, anti-comedone.

Azelaic acid does not have a fashionable moment. It has never trended. It also has a working presence in three of the most-searched skin concerns: rosacea, post-inflammatory pigment, and comedonal acne. At 10% to 15% it clears sensitised acne without provoking barrier collapse and, at the same time, quietly lifts the pigmentation the acne left behind.
Pregnancy-safe. Compatible with most other actives. Works on Fitzpatrick IV to VI where hydroquinone would provoke rebound. Every routine that treats acne and pigment together should at least consider it.

Why we test on Fitzpatrick II to VI.
Most published cosmetic trials still cluster around Fitzpatrick I to III. That is not the customer we serve.
