Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Skin irritation (mild redness or stinging) | Uncommon | Generally well tolerated; transient irritation may occur, particularly at higher concentrations or on compromised skin. |
| Allergic contact dermatitis | Rare | Isolated case reports exist; considered a low-risk sensitizer compared to many traditional preservatives. |
| Mild skin irritation | Uncommon | Transient redness or stinging, more likely on compromised or sensitive skin. |
| Eye irritation | Uncommon | Can occur with direct contact in eye-area products. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Mild irritation or stinging | Uncommon | Transient sensation typically on sensitive or compromised skin. |
| Photosensitivity-related reaction | Very rare | Limited anecdotal reports; not well established in research. |
