Arnica gel is typically applied to a bruise 2 to 4 times a day, gently massaged into unbroken skin until the discoloration fades, though product strength and label directions vary. Several factors affect the right frequency for you, including the size and age of the bruise, your skin sensitivity, and whether you are also using ice, compression, or other topical products. Arnica should never be applied to open wounds, and bruises that appear without injury, spread rapidly, or come with swelling, severe pain, or frequent bleeding may point to something more than a simple bump. See below to understand the full dosing details, safety cautions, and warning signs that deserve medical attention. If you are unsure whether your bruising is normal healing or a sign of an underlying issue, a free, instant, online symptom check can help you interpret your symptoms in minutes and decide whether home care is enough or a clinician should take a look.
