TST

TST (Tin's Secret) evokes a highly polarized customer sentiment, largely shaped by its multi-level marketing (MLM) business model and significant controversies. While a segment of loyal distributors and customers praise specific skincare products, particularly the yeast mask, for perceived efficacy, a substantial portion of public opinion is negative. Many consumers express skepticism regarding product pricing, question the efficacy claims, and report adverse skin reactions. The brand has faced widespread accusations of operating a pyramid scheme and has been subject to legal investigations in China for alleged illegal MLM activities and product quality issues. This has severely damaged its reputation, leading to a prevalent perception of TST as a controversial and untrustworthy brand, overshadowing any positive product experiences for many.
