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 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. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| 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. |
| Mild skin irritation or redness | Rare | Generally considered non-irritating; occasional mild reactions reported. |
| Clogged pores / comedogenic-related breakouts | Uncommon | Often anecdotal; dimethicone is largely regarded as non-comedogenic but may trap debris if skin is not cleansed well. |
| Allergic contact dermatitis | Very rare | True silicone allergy is exceptionally uncommon. |
| Eye irritation on accidental contact | Rare | Transient stinging or discomfort if product enters the eyes. |
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically in sensitive or compromised skin. |
| Comedogenicity / acne flare | Rare | Low comedogenic potential, but may contribute to clogged pores in acne-prone individuals at high concentrations. |
| Skin dryness | Common | High concentrations can strip natural oils and reduce skin hydration. |
| Irritation or stinging | Common | Especially on compromised, sensitive, or freshly exfoliated skin. |
| Disruption of skin barrier | Uncommon | Repeated exposure may impair barrier function with frequent use. |
| Contact dermatitis | Rare | Irritant or allergic reactions reported in susceptible individuals. |
| Allergic contact dermatitis to ethanol itself | Very rare | True ethanol allergy is uncommon and documented in isolated cases. |
