Dial for Men Magnetic Older/Newer Version Difference . ?

I was looking up dial magnetic and I noticed that yes there is the clean rinsing and moisture versions but they come in a black bottle (old) and silver bottle (marked as ‘new look’). Was this just an appearance change or does one version work better than the other . ? I attached some pics .

(Note: both the clean rinsing and moisture versions were made in the old version as well as the new version)

Probably just a packaging change. No one actually knows how much a1 is in the bottle. Some people have had success, i really didn’t see anything. I’m not sold on the application of a soap and phero at the same time.
