This research is based on the legal protection of consumers on overclaiming information about skincare products in advertising that can harm consumers. This research discusses legal protection for consumers over the occurrence of overclaims in skincare marketing and the responsibility for businesses that still use the word overclaim in product claim information. The research method used is normative research with statutory and conceptual approaches. Data collection is done by document study and interviews. The research data was analyzed descriptively and qualitatively. The results of this study indicate that overclaiming information results in dishonest, non-transparent, non-objective, untrue, and misleading information, which results in losses to consumers (material and immaterial losses, namely lost money, wasted time, skin damage, and emotional disappointment) and is a prohibited business practice because it violates several written regulations. Consumers who suffer losses need to be held accountable by business actors as explained in Articles 19-20 of the GCPL, Article 1365 of the KUHPer, and BPOM Regulation No. 3 of 2022, besides business actors who still violate can be subject to administrative sanctions and criminal sanctions.
