Questions
- Is a 10% azelaic serum the same as prescription azelaic acid?
- No. Cosmetic suspensions around 10% are formulated for the appearance of an even, clear-looking complexion. Prescription azelaic acid is a higher-strength drug with different, regulated uses. It is a separate product entirely.
