Chlorine Exposure and Free Radical Damage in Skin

• Direct Oxidative Stress: Chlorine is a potent oxidant. When skin is exposed to chlorinated water (such as in swimming pools), it can react directly with lipids, proteins, and amino acids in the skin's surface and barrier layers.
• Depletion of Antioxidants: This chemical reaction rapidly depletes the skin's natural antioxidant defense network—most notably Vitamin E, Vitamin C, and reduced glutathione—leaving the cellular structures more vulnerable.
• Lipid Peroxidation: By stripping away or oxidizing protective sebum and cell membrane lipids, chlorine can trigger a cascade of lipid peroxidation, which generates secondary free radicals and compromises the skin barrier function.
• Inflammatory Response: The resulting oxidative stress and cellular irritation often provoke localized inflammation, accelerating premature skin aging, dryness, and potential irritation or dermatitis.
