Abstract
The present invention relates to a non-therapeutic makeup and/or care process for non-fibrous human keratin matter, such as the skin, the lips and the fingernails, comprising the following steps: placing a heating device on or near an outer surface of a lump of a solid cosmetic composition to heat said lump locally in such a way as to soften essentially only said outer surface and lower its coefficient of dynamic friction and then apply the outer surface of the heated composition to the region to be treated, said solid cosmetic composition comprising in a physiologically acceptable medium at least one semi-crystalline polymer.
