Bayer said on Monday it was willing to offer more than $65 billion, a 2 percent increase on its previous offer for the world's largest seeds company Monsanto.

The dermatology business could attract interest from existing makers of skincare products including Nestle SA's <NESN.S> Galderma, Allergan Plc <AGN.N> and Almirall SA <ALM.MC>, as well as private equity firms, according to the Bloomberg report.

Bayer and J.P. Morgan were not immediately available for comment.
