Common Name(s): Arnica extract,mountain arnica extract
DESCRIPTION
What It Does: Reduces bruising, edema, and inflammation with helenalin's potent anti-inflammatory activity.
Why It's Used: Clinically proven botanical for bruise resolution and post-procedure inflammation reduction โ the gold standard natural anti-bruising active.
How It Works: Helenalin inhibits nf-kb transcription factor by alkylating its p65 subunit cysteine residues. reduces vascular permeability preventing edema formation. inhibits cox-2 for anti-inflammatory/analgesic activity.
Typically Found In: Post-procedure recovery,anti-bruising products,sports recovery

Halal Status: Yes
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Do not apply to open wounds or mucous membranes. allergic contact dermatitis possible in asteraceae-sensitive individuals.
Safe for Sensitive Skin: Yes โ particularly recommended for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Avoid on broken/open skin. helenalin is cytotoxic at high concentrations โ use at recommended formulation levels only.
Works Well With: Ceramides,panthenol,allantoin,hyaluronic acid,centella asiatica
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Helenalin's mechanism of nf-kb inhibition via direct cysteine alkylation is unusual among plant-derived anti-inflammatories โ most work via receptor agonism or enzyme inhibition rather than direct transcription factor modification. this covalent mechanism explains helenalin's exceptional potency but also its cytotoxicity at excess concentrations.
