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. |
| Transient mild stinging or irritation | Rare | Possible on compromised or highly sensitive skin, usually self-limiting |
| Contact dermatitis or allergic reaction | Very rare | Uncommon given the simple mineral water composition |
| Skin dryness | Common | High concentrations can strip natural oils and disrupt the skin barrier with repeated use. |
| Irritation or stinging | Common | More likely on compromised, sensitive, or already dry skin. |
| Barrier impairment | Uncommon | Frequent exposure may reduce barrier function and increase transepidermal water loss. |
| Contact dermatitis | Rare | Irritant or, less often, allergic reactions reported in susceptible individuals. |
| Worsening of conditions like eczema or rosacea | Uncommon | Can aggravate inflammatory or reactive skin types. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| 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. |
| Contact allergy/sensitization | Very rare | Polyglycerols are low-sensitizing; documented allergic reactions are exceptional |
| Irritation | Rare | Mild irritation or stinging may occur, particularly on sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Sensitization is uncommon as it is generally considered non-sensitizing. |
| Eye irritation | Rare | Can cause transient stinging if it migrates into the eyes in eye-area products. |
