A self dosing skin composition and method releases sun blocking agent or other active ingredient onto the skin of a user as a function of exposure to at least one environmental condition over time. The environmental condition is preferably exposure to sun light, in particular, harmful UV radiation. The composition includes a medium adapted to be spread onto the skin of a user and a reservoir defining at least one wall for containing at least one sun blocking or other agent. The reservoir is dispersed in the medium and the wall is designed and/or selected to deteriorate over time with exposure to the environmental condition or conditions, for releasing the agent into the medium and onto the skin. At least one agent is provided in the reservoir. The reservoir is preferably in the form of a multiplicity of microcapsules dispersed in the medium, each microcapsule having a wall containing the at least one agent, each wall deteriorating over time with exposure to the at least one environmental condition for opening the microcapsule to release the agent.
