Calendula Nano Extract is a nanoencapsulated form of Calendula officinalis (marigold) extract used in skincare for its anti-inflammatory, antioxidant, and wound-soothing properties. The nano delivery is intended to improve penetration and stability of active flavonoids and triterpenoids.
| Reported effect | How often | Notes |
|---|---|---|
Allergic contact dermatitis | Uncommon | More likely in individuals sensitive to Asteraceae/Compositae family plants (e.g., ragweed, daisy, chrysanthemum). |
Skin irritation or redness | Rare | Transient stinging or erythema reported, often related to formulation rather than the extract itself. |
Contact urticaria | Very rare | Isolated reports of hives following topical exposure. |
Theoretical concerns over nanoparticle penetration/systemic exposure | Rare | Limited long-term safety data specific to nanoencapsulated forms; reported mainly as a research caveat rather than confirmed clinical effect. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
