Calluna Vulgaris Flower Extract

Calluna Vulgaris (heather) flower extract is typically used at low concentrations as a botanical antioxidant/soothing agent, but plant extracts contain multiple bioactive compounds (e.g., polyphenols) that can trigger stinging or contact dermatitis in reactive or eczema-prone skin. While not a high-risk irritant like acids or surfactants, the variability of botanical extracts and documented potential for sensitization in fragranced/plant-derived ingredients warrants a mild score for patient safety. Safety Notes: In commercial skincare, Calluna vulgaris (heather) flower extract is most often used as a minor botanical additive in multi-extract blends for leave-on creams/serums and rinse-off cleansers at ~0.0005–0.05% (as supplied), where it functions mainly for marketing/antioxidant-support claims. Higher concentrations are found in consumer-available “botanical concentrate” serums, masks, and soothing creams where the extract (typically glycerin/propylene glycol or water-based, non-standardized) is used at ~1–5% to support antioxidant/anti-redness positioning. There is no specific EU/FDA concentration limit for this plant extract; practical upper use is constrained by odor/color, tack/solvent load, and stability/compatibility rather than regulation, and rinse-off products typically sit toward the lower end of the range.
