Highlights
► We study theoretically the response of a membrane to a local chemical perturbation. ► Chemical perturbations affect the spontaneous curvature and the equilibrium density. ► The ratio of these two effects can be inferred from the membrane dynamical response. ► Local asymmetric density perturbations relax by spreading diffusively. ► This diffusive spreading is controlled by intermonolayer friction.
