Expert Verdict

EU 2024/996 Annex III restricted: beta-arbutin 7% face creams only. SCCS/1642/22 (Jan 2023). Hydroquinone release is central safety concern (enzymatic, acid-catalyzed, UV-mediated). Hydroquinone is Annex II entry 1339 (prohibited) and must remain at unavoidable traces (3 ppm LOQ, 1 ppm LOD). Transition: Feb 2025 placement, Nov 2025 withdrawal. UK has not adopted 2024/996. Japan/Korea approved as quasi-drug/functional cosmetic whitening active. Claims: brightening acceptable; whitening and bleaching prohibited globally.
