Abstract
Cosmetic compositions are provided, which are capable of having a tightening and/or curling effect on a human integument when applied thereto. Cosmetic compositions according to the invention typically include a cosmetically acceptable vehicle and a pH-dependent film-forming polymer of either a poly(methacrylic acid-co-methyl methacrylate) or a poly(methacrylic acid-co-ethyl acrylate). The tightening and/or curling effect of these cosmetic compositions is prolonged and substantially resistant to environmental stresses such as increased heat or humidity.
