Ascorbyl Glucoside (Korean: 아스코빌글루코사이드) is recorded here as a functional-cosmetic ingredient within Korea’s regulatory framework. It appears on the Ministry of Food and Drug Safety (MFDS) list of ingredients whose efficacy data may be omitted for a functional cosmetic — specifically under the “skin whitening” category of Annex 4 of the Regulation on the Review of Functional Cosmetics (고시 제2025-88호).
Being on this list means the regulator has predefined an approved ingredient, a maximum content, and a fixed efficacy phrase for skin whitening products. It does not describe how well the ingredient works, nor does it authorize any wording beyond the notified phrase. This page organizes what the notification actually states, and where the boundary of that statement lies.
Ascorbyl Glucoside is used in cosmetic formulations in the skin whitening category. Under the notification, its permitted content is 2%, and its use is limited to lotion, liquid, cream, and sheet-mask (침적 마스크) product forms.

Claim Safety Matrix
⚠️ Claim classification below reflects the DB record and requires human regulatory review before publication.
| Claim Text | Claim Type | Why It Matters | Safer Alternative Wording | Source |
|---|---|---|---|---|
| “피부의 미백에 도움을 준다” (“helps with skin whitening”), at 2% content in the specified product forms | Allowed | This is the exact efficacy phrase the notification fixes for the skin whitening category. It is permitted only at the notified content (2%) and product forms; the wording itself is defined by the regulator, not chosen by the marketer. | Use the notified phrase verbatim: “피부의 미백에 도움을 준다.” | MFDS 고시 제2025-88호 별표4 |
| “미백 치료” / “기미·잡티 제거” / “표백” (“whitening treatment / removes blemishes / bleaching”) | Avoid | The notified efficacy is limited to “helps with skin whitening.” Treatment, removal, or bleaching wording implies a drug-like or complete-removal effect. | Replace with the notified phrase “피부의 미백에 도움을 준다.” | MFDS 고시 제2025-88호 별표4 (efficacy scope limit) |
Evidence Boundaries: What This Page Does Not Claim
The following claims are outside the scope of this ingredient record:
No disease treatment or prevention. The notification defines a cosmetic skin whitening function only; it does not support treating or preventing any skin disease or disorder.
No drug-like efficacy. Treatment, removal, or bleaching wording implies a drug-like or complete-removal effect. Such wording implies a pharmaceutical or complete-effect claim that exceeds the notified phrase and is not supported here.
No guaranteed or individual results. Regulatory listing predefines an approved phrase and content; it does not measure or guarantee any individual outcome.
No content or efficacy beyond the notification. Content above 2% or product forms outside the notified list (lotion, liquid, cream, sheet mask) fall outside this record.
