Brenda_Bottems - It's called
body paint - a form of art. It's practically always done in intense and/or bright colors. This is actually pretty mild and modest compared to how it's often done. Also, as
chantilly said, Tessa is supposed to resemble a peacock - it's not just "garish" body paint without any idea behind it. Plus, their slogan is about "feeling good in one's skin", if I remember correctly, and the particular ad is for micellar water meant for removing make-up and cleansing the skin, so showing some skin is appropriate. In my opinion, with the body paint, beautiful movement and skating this ad is much more tasteful and closer to art than most "normal" skin care product ads tend to be.
As an aside, I would agree that some of the examples we can see in that link are quite tasteless, but I am surprised by this notion which many people seem to have that bright and colorful = automatically tasteless. Another notion which I personally don't agree with is that nakedness, even shown in a non vulgar way, without actually showing much, is automatically tasteless as well.
This is even more off-topic, but, given how many people here seem to love music from Cirque du Soleil, I wonder do they even watch Cirque du Soleil itself and, if they do, how can they accept the costumes that the acrobats and dancers etc. are wearing and how can they keep their eyes from bleeding out with the wide-spread taste here

.
As for the "second-rate" skin cream, I have read that Tessa herself has been using Nivea since she was very young, so it's not surprising at all that she now has an advertising contract with them.
