I don't know of anything "special", but just be consistant in applying it. Don't skip a day.
Do it yourself spa scrub - mix 1 cup sugar with 1/2 cup virgin olive oil and 2 tbspoons lemon juice.
My naturopath says to use sesame oil on my skin and to take a tablespoon internally every day. It also helps my platelets. He swears by it. Sesame oil absorbs into the skin so you're left with an oily sheen on your skin. I bought a small spray bottle (the little travel size) and spray the oil on my skin. Works great. Now I need to get into the habit of using it every day.
