NEEDLY Azelaic Acid and Glutathione Serum, 15% Azelaic Acid, 30 ml

An intensive serum designed to address breakouts, post-acne marks, and uneven skin tone, combining a high concentration of azelaic acid (15%) with an antioxidant complex for multi-level action. It targets active inflammation and its underlying causes—excess sebum, bacterial activity, and heat buildup in the skin. It gradually evens out skin tone and helps make the skin less reactive. A key feature of the formula is its pronounced cooling effect: after application, skin temperature drops by an average of 4.47°C, which helps quickly reduce redness and stop the “triggers” of inflammation. With regular use over 4 weeks, a reduction in the area of inflammatory lesions is observed, and the zero-irritation formula is suitable even for sensitive skin. The serum works by “breaking the inflammatory cycle”: when exposed to UV rays, the skin overheats, sebum production increases, and the process of breakout formation is triggered. The cooling effect lowers the skin’s temperature, while azelaic acid inhibits the growth of Cutibacterium acnes bacteria and regulates keratinization processes; glutathione and niacinamide address skin tone and post-inflammatory hyperpigmentation. Special emphasis is placed on reducing redness and sensitivity—which often persist even after the breakouts themselves have cleared up—thanks to madecassoside.
