Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |
| Allergic contact dermatitis | Very rare | Documented in isolated case reports; true sensitization is unusual. |
| Mild skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
| Skin irritation | Rare | Generally considered low-irritant; mild irritation reported occasionally, often related to other formulation components. |
| Acneiform breakouts / pore congestion | Rare | Considered low comedogenic potential, but occlusive film may contribute in acne-prone individuals. |
| Eye irritation | Rare | Possible mild stinging or irritation upon direct ocular contact. |
| Contact dermatitis / allergic reaction | Very rare | Allergic sensitization to this inert hydrocarbon is uncommon. |
| Comedogenicity / clogged pores | Rare | Considered low comedogenic potential, but possible in acne-prone skin with heavy use. |
