When evaluating skincare cosmetics, not only the “Touch”but also the “Feeling”and “Affection”are important factors. Therefore, we have conducted studies to evaluate the emotional changes caused by the use of skincare cosmetics. Also, the actual period of use for a skincare cosmetic-moist lotion and milk lotion, for example, is usually 1 to 2 months or longer. This means that we must evaluate repeatedly in a certain span in order to develop skincare cosmetics. Accordingly, we have attempted to catch the affection which changes within the long-term use. When one uses skincare products for the first time, the “Touch”is the most important factor, whereas the factors change to the “Affection”or “Effect on skin”, etc., as time passes. This result suggests that an evaluator's criterion changes in a long-term use. It is considered that this is an important factor in developing not only cosmetics but all products. The evaluation of affection has great importance on the development of skincare cosmetics.
