Medicube Azelaic Acid 16 BB Calming Serum Mask provides a high-potency solution for those battling persistent skin texture issues and visible reactivity. By concentrating the power of a professional-grade serum into a single-use sheet mask, this treatment acts as a rapid reset for compromised skin. The formula harnesses 16% Azelaic Acid , a powerhouse ingredient that works to refine pore appearance, regulate excess sebum production, and neutralise surface redness. Supported by Niacinamide and Pantothenic Acid, the mask creates a dual-action effect: it aggressively targets acne-related concerns while simultaneously fostering a regenerative environment to fade dark spots and unify uneven tone. This mask serves as the essential remedy for skin that feels reactive, stressed, or prone to breakouts, providing a direct route to a balanced, luminous complexion. Why You Will Love It: Potent Azelaic Concentration: Contains 16% Azelaic Acid to actively purify pores, reduce redness, and smooth uneven surface texture. Rapid Calming Action: Blends Aloe Vera and Propanediol to immediately cool the skin, providing instant relief for hot or reactive areas. Visible Tone Correction: Infused with Niacina mide to systematically fade dark spots and hyperpigmentation, resulting in a more uniform complexion. Regenerative Support: Incorporates Pantothenic Acid to bolster the natural barrier, encouraging skin recovery and resilience. How to Use: Apply to clean skin after toner. Position the mask carefully over your face, avoiding the eye and lip areas. Leave on until the sheet begins to turn transparent, then remove. Gently dab any remaining essence into the skin until fully absorbed.
