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. |
| Skin irritation or stinging | Uncommon | May occur on sensitive or compromised skin, partly due to residual aromatic compounds. |
| Allergic contact dermatitis | Rare | Reported in individuals sensitized to rosemary or related Lamiaceae plant constituents. |
| Fragrance-related sensitivity | Uncommon | Trace volatile components can trigger reactions in fragrance-sensitive users. |
| Photosensitivity | Very rare | Limited and inconsistent reports; generally low risk for the hydrosol form. |
| Sticky or tacky skin feel | Common | Cosmetic sensation at higher concentrations, not a health concern. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or with high concentrations. |
| Skin dryness or moisture-wicking in very low humidity | Uncommon | Can theoretically draw water from skin in extremely dry environments if not paired with occlusives. |
| Skin irritation | Uncommon | Can cause redness, stinging, or burning, particularly in sensitive or compromised skin. |
