Buddleja Officinalis Flower Extract

Buddleja officinalis flower extract is a botanical antioxidant/soothing extract typically used at low concentrations, but like many plant extracts it contains multiple bioactive compounds that can trigger irritation or allergic contact dermatitis in reactive or eczema-prone skin. Robust clinical patch-test data specifically isolating this extract is limited, so for patient safety I score it as mild: generally tolerated but with a non-trivial risk of sensitivity, especially in compromised skin or multi-ingredient routines. Safety Notes: In mass-market leave-on skincare (SPF, day creams, anti-pollution/blue-light serums), Buddleja officinalis flower extract is typically used as a minor antioxidant/photoprotective support at trace-to-low levels (often via blends), with commercial formulas commonly landing around 0.01–0.5%. Specialty “urban defense/blue-light” products and concentrated botanical serums sometimes dose the extract much higher, with observed OTC maxima around ~2–3% depending on extract potency/solvent system and sensory constraints. Rinse-off cleansers generally sit toward the low end due to short contact time and cost/clarity limits, while leave-on products span the full range.
