摘要：
A cosmetic or dermatological composition comprising a graft copolymer having a backbone comprising a copolymer with a glass transition temperature ranging from 0 to 30.degree. C., capable of being obtained by radical polymerization or by polycondensation and comprising on the backbone chain at least one graft unit including a hydrophobic macromonomer with a glass transition temperature higher than 25.degree. C.
