<p>Provided are: a cosmetic product having high sun protection factor, wherein a booster effect of amplifying the ultraviolet absorbing/blocking ability of an organic ultraviolet absorbent or an inorganic ultraviolet blocking agent that is dispersed in an emulsion composition is exhibited by means of an effective ultraviolet scattering effect of polyamide porous fine particles; and an SPF booster which is used in the cosmetic product. The present invention relates to: a cosmetic product which is composed of an emulsion composition wherein an organic ultraviolet absorbent and polyamide porous particles having a spherulite structure, a number average particle diameter of 1-30 µm and a particle size distribution of 1-2.5 are added independently from each other; and an SPF booster which is characterized by being mainly composed of polyamide porous particles that have a spherulite structure, a number average particle diameter of 1-30 µm and a particle size distribution of 1-2.5.</p>
