A method for improving skin condition of a wearer in the area covered by a treated absorbent article, the method comprising the following steps: (a) applying to the wearer an unused treated absorbent article having a skin care composition that improves skin condition upon transfer to the skin of the wearer; (b) transferring to the wearer at least a portion of the skin care composition from the unused treated article during wear whereby the unused treated article is transformed to a used treated article; (c) removing the used, treated article from the wearer; and (d) repeating steps (a), (b), and (c) with six or more additional unused, treated articles for at least a 24 hour period; wherein the skin care composition is semi-solid or solid at 20° C. and comprises: (i) from about 5 to about 95% of an emollient; and (ii) from about 5 to about 95% of one or more agents capable of immobilizing the emollient on or in the treated article, the one or more immobilizing agents having a melting point of at least about 35° C. whereby at least 0.03 mg/in2(0.0047 mg/cm2) is transferred to the wearer's skin over the 24 hour period so as to cause an improvement in skin condition in the area of a wearer covered by the treated absorbent articles having a skin care composition, relative to skin covered by untreated absorbent articles that do not comprise the skin care composition, is manifested in terms of a skin condition measure selected from the group consisting of: (1) smoother skin as measured via image analysis of skin casts and (2) reduced squamous cell release in the D-Squame tape analysis. 21.
