This experimental research aimed at (1) to develop an original product which affects moisturizing skin (2) to compare the moisturizing before and after using Bath Bomb product and to increase the moisturizing. (3) to investigate the satisfaction of the Bath Bomb after using the product. And (4) to explore the relationship between moisturizing value and satisfaction after using the product. The participants were 20, had healthy. The experimental method of the original product had a stable in colour, smell, and product characteristics. This experiment studied on Single-blind control study, efficiency study, and the product satisfaction by corneometer (30 minutes, 7 days, and 14 days after using) The data collection was a questionnaire and used statistical program for data analysis: Percentage, Average and Standard Deviation P-value Paired Sample T-Test statistical experiment. The result showed that the Bath Bomb product can increase the moisturizing after using for 30 minutes which equals 46.99+10.32 (the reliability at 95% P<.05) after using Bath Bomb product, it can increase the moisturizing skin for 7 days which equals 46.53+10.45 (the reliability at 95% P<.05). And after using the Bath Bomb product, it can increase the moisturizing skin for 14 days which equals 47.96+8.84 (the reliability at 95% P<.05). Most of the participants satisfied at a good level for the evaluation of the physical part, usability, efficiency, and recommendations, which were at 38.34, 76.9 and 61.5, respectively. Also, there was no statistical relationship at 95 % (the reliability value) between the product satisfaction and the increase of moisturizing value.
