WHAT THE RESEARCH SAYS
ALL 15 ON PUBMED ↗BASED ON 15 PUBMED STUDIES
01
IN VITRO STUDY⚠ LAB-BASED ENZYME SCREENING DOES NOT DIRECTLY PREDICT REAL-WORLD SKIN-LIGHTENING RESULTS IN LIVING PATIENTS.
02
REVIEW⚠ COMPARATIVE CLINICAL EFFICACY DATA BETWEEN PLAIN KOJIC ACID AND ITS DERIVATIVES IN HUMAN PATIENTS ARE NOT EXTENSIVELY REPORTED IN THESE ABSTRACTS.
Kojic acid derivatives are more stable and effective than plain kojic acid for reducing pigmentation.
03
SYSTEMATIC REVIEWPUBLISHED 2022⚠ KOJIC ACID IS NOT DIRECTLY COMPARED HEAD-TO-HEAD AGAINST TRIPLE THERAPY OR HYDROQUINONE IN THIS REVIEW; IT IS GROUPED WITH OTHER FIRST-LINE AGENTS WITHOUT SPECIFIC EFFICACY RANKINGS.
First-line topical treatments for dark spots typically combine multiple depigmenting agents rather than kojic acid alone.
