No fungal-acne, pore-clogging, fragrance or drying-alcohol flags for Aqua in our reference data.
Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery.
| 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. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
