what ph level can melt skin
If you use a soap that's too alkaline, it will break up the acid in your skin, causing dryness. The pH level of most skin cleansers is slightly higher than 5.5, so the cleanser can break down dirt and oil on your skin. However, soap -- especially bar soap -- typically has a pH level of 9 to 12, which is too high if you're trying to keep your skin moist. Cleansers with lower pH levels leave your skin intact instead of breaking down the fatty tissue [source: Draelos ].
