Leontopodium Alpinum Extract

Leontopodium alpinum (edelweiss) extract is typically used at low concentrations as an antioxidant/soothing botanical, and it is generally well tolerated in routine leave-on products. However, as a complex plant extract with multiple phenolic constituents, it carries a non-zero risk of irritation or allergic contact dermatitis in highly reactive or eczema-prone individuals, especially when skin is compromised. Given patient-safety considerations for sensitive populations, it fits best as a gentle but not universally inert ingredient. Safety Notes: In mass-market leave-on moisturizers/serums and sunscreens, Leontopodium Alpinum (edelweiss) extract is often used at very low levels (down to ~0.0001–0.01%) when supplied as a diluted glycerin/propylene glycol extract or as part of a multi-extract complex. Many premium antioxidant/anti-aging leave-on products use it around ~0.05–1% (either as the commercial extract as-supplied or standardized actives), while a small number of consumer-available “high-strength” edelweiss serums/ampoules and single-hero botanical formulas reach ~2–5% extract load; rinse-off products typically sit toward the low end due to shorter contact time and cost/benefit considerations.
