Evidence checkGrade B · MFDS ✓
🇰🇷 MFDS-certified functional cosmetic brightening (미백) · anti-wrinkle (주름개선)Filed with Korea's FDA as 「구달청귤비타씨잡티세럼」 — a regulator-reviewed efficacy claim, not a marketing one.
Grade BDerivative vitamin C: gentler but less potent than L-AA; honest for beginners, not for stubborn melasma.
