Glutathione: effective % & pH 글루타치온
⏱ 1 min read
⚡ Quick answer: Glutathione: effective concentration no standardised topical concentration exists, optimal pH 5.0–7.0, evidence Limited. Harmless in a serum, unlikely to do much. Injections and drips are a medical decision with genuine safety questions — talk to a doctor, not a clinic salesperson.
How much Glutathione actually works? Here's the dosage, pH and evidence — the formulator-level read behind the % on a Korean label.
| Effective % | no standardised topical concentration exists |
|---|---|
| Optimal pH | 5.0–7.0 |
| Evidence | Limited |
| Onset | unclear — topical evidence does not support a reliable timeline |
What the % on the label really means
Harmless in a serum, unlikely to do much. Injections and drips are a medical decision with genuine safety questions — talk to a doctor, not a clinic salesperson.
⚠️ Ceiling: It oxidises readily and penetrates poorly, so a higher listed percentage does not translate into more reaching skin.
