Dipsacus Sylvestris Extract

Dipsacus sylvestris (wild teasel) extract is a botanical antioxidant/soothing claim ingredient typically used at low concentrations, but it lacks robust, standardized human patch-test data and can contain variable phytochemicals (e.g., iridoids/polyphenols) that trigger stinging or dermatitis in highly reactive or eczema-prone skin. In clinical safety practice, non-fragrance plant extracts without strong sensitization signals are usually tolerated, yet variability and allergy potential justify classifying it as mild rather than gentle, especially in compromised barriers. Safety Notes: Dipsacus sylvestris (wild teasel) extract is a niche botanical most often used as a minor supportive/marketing extract in leave-on anti-aging creams and serums, where it commonly appears at very low levels (around 0.001–0.1%) as part of multi-extract blends. Higher consumer-available levels are seen in “hero-ingredient” botanical concentrates and ampoules where the extract (or its supplier solution) is used at a few percent; the upper end observed in OTC products is about 5% before sensorial/color/odor and stability constraints typically limit further increases. It is primarily used in leave-on products; rinse-off formats tend to sit at the low end because of short contact time.
