Shiseido's carbonated foam muscle base liquid has been used all the time, and a bottle can be used for about 90 times, which is still very cost-effective! Moreover, it has a faint refreshing citrus fragrance when used, and also has a relaxing effect. Elastic bubble stimulation makes users feel comfortable physically and mentally, and it feels particularly good to use. Thanks for your support. I hope my answer is useful. Welcome questions. Thanks again!
