Debara Bertin is a model from the seventies and eighties who, when she was working in Paris, was represented by the Covers agency.
In the early eighties, she was prominently featured in an ad for Revlon's European Collagen Complex cream, from which this picture is taken. The ad promised younger-looking skin within ten days after beginning use of the product. The focus here on her full face, with her hair pulled back, certainly made for an effective selling point. :-)
