Screenshots for the ad. I looked up who the blonde is, and in 3 places it states Yvonne Zimer ... who I cannot find anywhere, I have even used different spellings. So if you can confirm this person or know if its a different person, I will add their name to the title area of this post. Sanofi is the owner of Act products and they are a European company. It could be that their ads are done in France and not the U.S., making it hard to locate the actresses and actors in the Act ads.
