Azelaic Acid 12% Serum (30ml)

TIRTIR’s Azelaic Acid 12% Serum is a powerful yet gentle solution for acne, redness, and uneven skin tone, designed especially with oily, sensitive, and acne-prone skin in mind. At the heart of this formula is a highly effective 12% concentration of Azelaic Acid, a multitasking hero naturally found in grains like rye and barley and also produced by the yeast present on healthy skin. Renowned for its unique ability to both calm and clarify, Azelaic Acid gently exfoliates away dead skin cells, unclogs congested pores, and smooths out bumpy or rough texture, while its antibacterial and anti-inflammatory properties directly target the causes of breakouts. Beyond tackling acne, it also helps to fade lingering dark spots and post-acne scarring by slowing down excess melanin production, revealing a brighter and more even-toned complexion over time.

The formula is strengthened with Zinc PCA, which regulates excess sebum to prevent clogged pores and shine, and Panthenol, a deeply soothing hydrator that promotes healing and delivers instant relief to irritated skin. To ensure lasting hydration and comfort, TIRTIR’s Hyal-Zip™ technology combines polymerised hyaluronic acid with a moisture-locking delivery system that restores skin’s hydration balance and reinforces the barrier against dryness. Meanwhile, Ceramide NP and Betaine nourish the skin, replenish essential moisture, and prevent tightness or flakiness often caused by acne treatments.

For maximum efficacy, TIRTIR employs its innovative FLEX-SOME™ technology, encapsulating active ingredients into ultra-fine particles that are 2,500 times smaller than pores, ensuring fast, deep absorption where it’s needed most. The result is visible improvement: in clinical trials, redness was reduced by an impressive 73.4%, outer skin hydration increased by 201.79%, and inner layer hydration improved by 10.52% immediately after use.* The serum has also been tested for non-comedogenicity, so you can trust that it won’t clog pores or worsen breakouts.

Lightweight and non-irritating, this serum glides onto the skin and absorbs seamlessly, making it an easy addition to any routine. With consistent use, it balances oily yet dehydrated skin, reduces redness, calms inflammation, and visibly diminishes stubborn blemishes and dark marks.

*According to results obtained in clinical trials conducted by Dermacosmetic Skin Science Research Centre Co., Ltd., between 3/2/2025 and 5/3/2025, involving 20 adult subjects between 20 and 59 years of age.
