Beauty hospitals often use the brand Yves Springs, which is very mild. This facial cleanser can be used for sensitive muscles and pregnant women, and it is milder than amino acid cleansing. Art Star itself is a very big cosmetic and plastic surgery hospital, and their own skin care products are mild. I bought this facial cleanser from them before, and then they gave it to me. It's surprisingly easy to use. It's an amino acid facial cleanser, which is milder than the amino acid facial cleanser I used before and has the function of removing makeup, but the makeup is thicker and waterproof. You'd better use cleansing oil first.
