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. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Allergic contact dermatitis | Rare | Documented in patch-test studies but considered a relatively weak sensitizer. |
| 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 | Rare | Generally only with impure formulations or already compromised skin. |
| Acneiform breakouts / clogged pores | Rare | Low comedogenic rating, but acne-prone individuals may occasionally react. |
| Mild transient skin irritation | Rare | Occasional redness or stinging, generally in sensitive or compromised skin. |
| Comedogenicity (pore clogging) | Rare | Low comedogenic potential, but possible in acne-prone individuals depending on formulation. |
| Mild skin irritation | Rare | Generally well tolerated; transient redness or irritation reported infrequently in sensitive individuals. |
| Skin irritation | Rare | Mild transient irritation possible in sensitive individuals. |
| Pore congestion/comedogenicity concerns | Very rare | Largely non-comedogenic and volatile, so buildup is minimal. |
