For many years, I thought the skin under my arms was different.  I had bumps and creases, and I assumed that went with the territory.  A few years ago, when I saw the ads for Dove's new-at-the-time deoderant & antiperspirant, I was encouraged to try it.  I was amazed.  Within a week or so, my skin had completely changed.  My underarms had become as smooth and soft as the rest of my skin.

Now, they even go a step further with their "Ultimate Clear" line.  It doesn't leave white marks on my clothing, AND my skin is soft. Double bonus!
