The magic thing about skin is what she lets in. The skin is permeable, porous. Being a barrier is only one dimension to the skin, the skin moves, in and out. The skin exhales sweat and toxins from the bod and inhales moisture, oxygen and nutrients. The sebum the skin creates actually has immune function- producing wound healing compounds that deal with bacteria and inflammation while keeping in much-needed moisture.
For best results, apply a couple squirts of oil after bathing, while your skin is still damp. This allows the oil to trap in the moisture that keeps your skin hydrated. For massage, apply liberally and think sweet thoughts.
