Sodium acetate is the sodium salt of acetic acid used in skincare primarily as a buffering agent and pH stabilizer, and to a lesser extent as a mild humectant. It is considered safe and non-irritating at typical cosmetic concentrations.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | May occur at high concentrations or with compromised skin barrier |
Transient redness | Rare | Generally minor and self-resolving |
Allergic contact dermatitis | Very rare | Sensitization is uncommonly reported |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
