  A skew brace, as introduced by L. Guarnieri and L. Vendramin, is a set with
two group structures interacting in a particular way. When one of the group
structures is abelian, one gets back the notion of brace as introduced by W.
Rump. Skew braces can be used to construct solutions of the quantum Yang-Baxter
equation. In this article, we introduce a notion of action of a skew brace, and
show how it leads to solutions of the closely associated reflection equation.
