Distilled water is purified water used as the primary solvent and carrier in many skincare formulations, helping dissolve ingredients and provide a base for emulsions. It has no inherent therapeutic activity on the skin.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or dryness with excessive contact | Rare | Prolonged or repeated water exposure can disrupt the skin barrier, but this is uncommon in formulated products. |
| Contact reactions to contaminants | Very rare | Reactions are generally attributable to additives or microbial contamination rather than the water itself. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
