Breakouts and persistent redness meet their match with the TIRTIR Azelaic Acid 12% Serum, a potent yet calming treatment designed for sensitive, acne-prone skin. That high-concentration formula utilises 12% azelaic acid to unclog congested pores and fade the stubborn marks left behind by previous blemishes. Zinc PCA works alongside the acid to regulate oily patches and reduce surface shine, while panthenol provides a hit of moisture that prevents the skin from feeling stripped or dry. By incorporating Heal-zip technology, the serum offers a significant boost to hydration levels while calming visible irritation. This lightweight liquid absorbs quickly, making it a reliable choice for those needing to balance a fragile moisture barrier while tackling recurring spots and an uneven skin grain. Why You Will Love It: High-Potency Blemish Control: Utilises 12% azelaic acid to refine skin texture and clear out pores without causing harsh irritation. Sebum Regulation System: Features Zinc PCA to manage excess oil and prevent future breakouts from forming. Intensive Redness Relief: Provides a clinically proven reduction in redness by calming the skin surface and evening out the tone. Dual-Layer Hydration: Employs Heal-zip technology and panthenol to increase moisture levels both on the surface and within the deeper skin layers. How to Use: Apply a few drops to a clean, dry face after your toner, focusing on areas with congestion or redness. Pat the serum gently into the skin until fully absorbed before following with a moisturiser.
