What are the differences between sls and sles, and which one is better for sensitive skin?

SLS (Sodium Lauryl Sulfate) and SLES (Sodium Laureth Sulfate) are both surfactants commonly found in personal care products. SLS is more harsh and can be irritating to sensitive skin, while SLES is milder and gentler. Therefore, SLES is generally considered better for sensitive skin due to its lower potential for irritation.
