TIRTIR Azelaic Acid 12% Serum — 30ml Lightweight Hydrating Treatment for Blemish-Prone Skin with Zinc PCA & Hyal-ZIP

TIRTIR Azelaic Acid 12% Serum is a lightweight, fragrance-free treatment designed to refine texture, help reduce excess oil, and hydrate blemish-prone or sensitive skin.

This concentrated serum combines 12% azelaic acid with Zinc PCA and Hyal-ZIP to address uneven tone and shine while supporting comfortable, hydrated skin. Formulated to absorb quickly and sit lightly on skin, the non-comedogenic solution aims to deliver noticeable smoothing and balance without clogging pores or leaving a heavy finish. The fragrance-free, fast-absorbing formula is suitable for layering under moisturizers and sunscreen in morning and evening routines.

How does this serum refine texture and even skin tone?

The 12% azelaic acid concentration works as the main active to promote a more uniform-looking surface and reduce the appearance of roughness. Azelaic acid is chosen for its ability to work on several common texture concerns while remaining appropriate for sensitive complexions when used as directed.

• Contains 12% azelaic acid for targeted texture improvement
• Lightweight vehicle helps deliver the actives evenly across skin
• Non-comedogenic base minimizes pore-clogging risk

Will it help control oil and shine without over-drying?

Yes — the formula balances oil-control ingredients with hydrating components so skin appears less shiny without feeling stripped. Zinc PCA helps regulate sebum appearance while Hyal-ZIP provides a dual-layer hydration system to keep skin plump and comfortable.

• Zinc PCA for visible oil control and a matte-balanced look
• Hyal-ZIP provides immediate and sustained hydration
• Designed to reduce excess shine while preserving skin moisture

Is this gentle enough for sensitive or reactive skin?

The serum is fragrance-free and formulated to be calming, with supportive ingredients that aim to reduce visible stress signals on skin. Fast absorption and a lightweight texture help minimize potential irritation from occlusion, but patch testing is recommended for those with very reactive skin.

• Fragrance-free to lower irritation potential
• Calming blend of soothing ingredients included
• Fast-absorbing Flex-some technology reduces residue

How should I incorporate this into my skincare routine?

Use the serum after cleansing and any water-based treatments, then follow with a moisturizer and sunscreen in daytime. Because of its active concentration, introduce the product gradually and consider alternating nights if sensitivity develops.

• Apply to clean, dry skin before moisturizer
• Start with every other night, increase as tolerated
• Always use sunscreen during daytime when using active ingredients

Who is this for: TIRTIR Azelaic Acid 12% Serum is aimed at people with blemish-prone, combination, oily, or sensitive skin who want a lightweight, non-comedogenic product to refine texture, manage shine, and add hydration. It suits users seeking a fragrance-free treatment that layers well under other products and fits both morning and evening routines with proper sun protection. If you have very sensitive skin or are using other strong actives, consult patch testing or a skincare professional before regular use.
