Same Manufacturers, Different Labels: Despite brands heavily marketing unique ingredients and ground-breaking clinical results, the reality is different. The vast majority of K-beauty products are formulated and produced by the exact same giant ODMs (Original Design Manufacturers) like Kolmar Korea and Cosmax. The actual differences in formulation and efficacy between competing brands are practically nonexistent.
Flawed Clinical Trials: I personally participated in human clinical trials for these products. During the testing period, I was also receiving professional dermatological treatments. Unsurprisingly, the final clinical results for the cosmetic product came out exceptionally high.
Poor Variable Control: The testing organizations did not strictly monitor or account for external factors like my dermatological procedures in the test group data. Therefore, it is impossible to guarantee whether the documented improvements came from the skincare product itself or the medical treatments.
