Glycerol (glycerin) is a naturally occurring humectant that attracts and retains water in the skin, helping to maintain hydration and support the skin barrier. It is widely used in cosmetic and dermatological formulations across all skin types.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient stinging or tingling on application | Uncommon | More likely on compromised or broken skin, usually brief. |
Skin irritation or redness | Rare | Generally well tolerated; irritation is uncommon at typical cosmetic concentrations. |
Allergic contact dermatitis | Very rare | Isolated case reports; glycerol is considered a very low sensitizer. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
