What the Science Says
Arnica is a flowering plant traditionally used in topical creams, ointments, and tinctures to reduce pain, swelling, and bruising. Some clinical trials suggest it may reduce post-surgical pain and muscle soreness after intense exercise when applied to the skin. It has also shown early promise as a topical treatment for cutaneous leishmaniasis, though that research is very preliminary.
What It Doesn't Do
Won't reliably reduce bruising or swelling after cosmetic eye surgery — a well-designed RCT found no benefit over placebo. Not proven to work for post-filler or post-Botox bruising despite heavy social media promotion. No evidence it works when taken orally for any of these uses. Don't expect it to replace standard anti-inflammatory drugs.
Evidence-Based Benefits
Topical arnica may reduce pain and jaw stiffness after wisdom tooth removal surgery.

Absorption & Bioavailability
Poor systemically — studies note high skin retention and low systemic absorption when applied topically, which is considered a feature for local use but limits any whole-body effects
Red Flags to Watch For
- Social media (TikTok, Reddit) heavily promotes arnica for aesthetic procedures with little scientific backing — 91% of posts endorse it without evidence
- Arnica contains sesquiterpene lactones that can cause allergic contact dermatitis, especially in people sensitive to plants in the daisy/Asteraceae family
- Homeopathic arnica products (ultra-diluted) are not the same as herbal arnica extracts — evidence from one cannot be applied to the other
- Evidence is inconsistent across surgical contexts — worked for wisdom tooth removal but failed for eyelid surgery, suggesting effects may be procedure-specific or unreliable
