  The potential for manipulating characteristics of skyrmions in a CrI$_3$
monolayer using circularly polarised light is explored. The effective
skyrmion-light interaction is mediated by bright excitons whose magnetization
is selectively influenced by the polarization of photons. The light-induced
skyrmion dynamics is illustrated by the dependencies of the skyrmion size and
the skyrmion lifetime on the intensity and polarization of the incident light
pulse. Two-dimensional magnets hosting excitons thus represent a promising
platform for the control of topological magnetic structures by light.
