The human skin is protected by a lipid-rich layer called sebum and a complex microbiome that maintains a slightly acidic pH. Chlorine, as a strong oxidizing agent, disrupts this delicate balance. Rather than simply washing away surface oils, chlorine chemically alters the lipids and denatures keratin proteins, which compromises the skin’s barrier function. This leads to increased Transepidermal Water Loss (TEWL), manifesting as dryness, irritation, and "tightness." Clinical observations suggest that this oxidative stress can exacerbate pre-existing conditions like atopic dermatitis (eczema) by allowing environmental irritants to penetrate the skin more easily.
