The pH level of a body wash is important as it can affect the skin’s natural pH balance. The skin’s pH is typically around 5.5, which is slightly acidic. Using a body wash with a pH that is too high or too low can disrupt this balance, leading to dryness, irritation, or even skin conditions like eczema. Body washes with pH levels closer to the skin’s natural pH are gentler and less likely to cause skin issues, making them more suitable for maintaining healthy skin.
