The skin roughness showed an improvement in the SEsc and SEsm parameters. The SEsc parameter improves, decreasing its values, 7 and 28 days after daily application of the product.
The SEsc parameter indicates the degree of dryness of the stratum corneum; the greater its value, the more the skin is hydrated as required for a well-aging products.
The SEsm parameter improves, increasing its values, after 28 days. SEsm indicates the degree of skin smoothness: the tighter the skin, the higher its values.
