Symphytum Officinale (comfrey) Extract is a plant-derived ingredient used in skincare for its soothing, moisturizing, and skin-conditioning properties, largely attributed to allantoin and rosmarinic acid content. It is commonly included to support skin barrier comfort and promote a smoother skin appearance.
| Reported effect | How often | Notes |
|---|---|---|
Allergic contact dermatitis | Rare | Localized redness, itching, or rash in individuals sensitized to comfrey or related Boraginaceae plants. |
Skin irritation | Rare | Mild transient stinging or redness, more likely on compromised or sensitive skin. |
Concern over pyrrolizidine alkaloids | Very rare | Naturally occurring alkaloids are hepatotoxic if ingested; topical cosmetic use typically employs PA-reduced extracts, and systemic risk from properly formulated products is considered minimal. |
