This amino acid-based facial cleanser gently cleanses with four types of collagen. Its foam breaks up easily, leaving skin feeling moisturized and not tight after cleansing. Contains patented core ingredient "recombinant human collagen*1," a bio-collagen with an amino acid sequence identical to that of collagen found in the human body. Its high affinity with skin allows it to blend seamlessly into the skin, providing exceptional moisturizing benefits and supporting the skin's natural barrier function. Precision manufacturing ensures consistent purity and quality, making it a safe ingredient used in medical and cosmetic applications. The rich, gentle collagen foam gently removes dirt, excess sebum, sunscreen, and light makeup while preserving the moisture of the stratum corneum. Features proprietary "C5HR Recombinant Collagen Complex*2" technology. This biomimetic complex technology combines different ingredients to perform specific functions, combining four types of recombinant collagen to deliver moisture deep into the stratum corneum and support the skin's barrier function, even when it's prone to sensitivity due to daily external stimuli.
