Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Allergic contact dermatitis | Rare | Localized redness, itching, or rash in sensitized individuals; oat proteins are a known but uncommon contact allergen. |
| Contact urticaria | Very rare | Hives or immediate skin reaction reported mainly in individuals with atopic dermatitis or oat protein sensitivity. |
| Mild stinging or transient irritation | Uncommon | Brief sensation on application, more likely on broken or highly reactive skin. |
| Mild transient stinging or irritation | Uncommon | More likely on compromised or sensitive skin, often due to its penetration-enhancing properties |
| Contact dermatitis or allergic sensitization | Rare | Glycol-type ingredients are generally low sensitizers but reactions are occasionally reported |
| Redness or dryness | Rare | Typically associated with high concentrations or already irritated skin |
| Mild stinging or tingling on application | Common | Usually transient and subsides shortly after application. |
| Erythema (redness) | Common | Generally mild and temporary, especially with higher concentrations or peels. |
| Dryness or flaking | Common | Result of increased cell turnover; often improves with moisturization. |
| Increased photosensitivity | Common | AHAs raise sun sensitivity; daily sunscreen is recommended. |
| Itching or irritation | Uncommon | More likely with sensitive skin or overuse. |
| Post-inflammatory hyperpigmentation | Rare | Generally lower risk than stronger AHAs, but possible in darker skin tones with irritation. |
| Chemical burn or blistering | Very rare | Associated with high concentrations, prolonged contact, or improper use. |
