The present invention provides a surface modifier for a rubber composition that can enhance appearance without decreasing ozone resistance of the rubber composition. The surface modifier for a rubber composition of the present invention includes a hydrocarbon-based anti-aging wax for rubber (B) and an appearance-improving agent (C), in which: the content of a linear monovalent primary alcohol is more than 1.5 parts by weight and less than 35 parts by weight per 100 parts by weight of the surface modifier for a rubber composition; per 100 parts by weight of the primary alcohol, the content of a component having 30 to 38 carbon atoms is more than 35 parts by weight; the content of a component having 12 to 26 carbon atoms is less than 25 parts by weight; and the content of a component having 42 to 68 carbon atoms is less than 25 parts by weight.
