" The fickle-fingers affair Another missed opportunity is known in hand lotion circles as “the fickle-fingers affair.” The story starts with Jergens, the No. 1 brand with the dominant share of market. First, the company introduced Jergens Extra Dry, a creamlike product in an era of liquidlike lotions. Jergens Extra Dry was really a significant innovation smothered by the similarity of names. The prospect didn’t recognize the difference. But the competition did. Chesebrough-Pond’s introduced Intensive Care. Now for the first time, the new creamlike lotion had a name which positioned the product clearly in the consumer’s mind. And the product took off. Of course, when Jergens realized what was happening, they countered with a brand called Direct Aid. But it was the old story of too little and too late because the marketing victory went to Intensive Care. Today Intensive Care is the No. 1 brand. It outsells Jergens, Jergens Extra Dry, and Direct Aid combined. But isn’t the brand really called “Vaseline Intensive Care,” a line-extended name? True, but customers call the product Intensive Care, not Vaseline. In the mind of the prospect Vaseline is petroleum jelly; Intensive Care is a hand lotion. "
