Azelaic Acid 12% Serum
SUMMARY OF REVIEWS
TIRTIR's Azelaic Acid 12% Serum is a hydrating, soothing formula that targets redness, breakouts, and post-acne marks without the peeling common in cream versions. James Welsh (skincare focus) notes it's buffered despite the strong 12% level, and has been cleared by cosmetic chemists as effective. It's best used as a targeted treatment when skin is acting up, like after flights.
