I have Type 2 diabetes. One of the hallmarks of this disease are the dark circles around the neck and the darkening of the underarms. I have suffered from this for years and avoided wearing sleeveless shirts because it looks like my underarms are always dirty. After reading the claims of the Dove Clear Tone deodorant ads, I was skeptical. I have tried EVERYTHING to rid myself of this embarrassing problem but it never would clear up enough for me to be comfortable. How would, or could, a deodorant help? Despite my skepticism, I decided to try it. After a week, I noticed that my underarm area was lighter in color than the previous week. I kept using Dove Clear Tone and I must say that my underarm area is no longer the pits (pun intended)! They are lighter in color, look very natural, and I am very impressed with this product. I have been buying it now for over 6 months, and I refuse to buy any other product. Thank you, Dove!
