The present invention relates a method for maintaining or improving skin health by repeatedly applying lotion-treated absorbent articles to a wearer. When applied with sufficient frequency, the skin in the area covered by lotion-treated absorbent articles shows equal or improved skin health, relative to skin covered by untreated absorbent articles that do not comprise a skin care composition. The present invention also relates to methods for assessing skin health in the area covered by an absorbent article.
