@dermapharmacist_: Azelaic acid serums — but the ingredients around it are what actually separate them. Purito combines azelaic acid with kojic acid and tea tree. Kojic acid is a well-known tyrosinase inhibitor, meaning it actively blocks melanin production to target dark spots and uneven tone. Tea tree adds antimicrobial support, helping keep acne-causing bacteria in check. The brightening stack here is genuinely strong — but because kojic acid can increase photosensitivity, this one is best saved for your PM routine to get the full benefit without the risk of UV-induced irritation. Aromatica pairs azelaic acid with PDRN and K-herbal extracts. PDRN (polydeoxyribonucleotide) works at the cellular level — it activates A2A receptors to stimulate tissue regeneration and reduce inflammation, which is why it's used in clinical skin repair. This matters because acne has three distinct phases: bacterial overgrowth, inflammation, and tissue regeneration. Azelaic acid handles the first two well, but that final repair phase needs a regenerative ingredient to actually close the loop. The herbal complex adds extra soothing support for compromised or sensitized skin. Anua formulates at a higher azelaic acid concentration, which gives it more potency for stubborn, persistent acne. Higher concentration means faster action on hyperkeratinization and bacterial activity — but also a higher chance of initial irritation, especially on a disrupted skin barrier. Buffering it with a moisturizer when you first introduce it gives your skin time to acclimate without triggering reactivity. All three use azelaic acid as the base. What's different is what each formula is designed to do beyond that — brightening, regeneration, or potency. Match the formula to the problem your skin is actually in right now.
