Second Skin

We all have a second skin (sometimes it's superficial)
From without or from within (can be beneficial)
When you have your second skin (all of it essential)
You can be almost anything (very superficial)

We all have a second skin (a real infatuation)
From without or from within (cause hyperventilation)
When you have your second skin (a close examination)
You can be anything (and you'll see the superstition)
