You cannot remove a hickey instantly
Apply a cold compress or ice wrapped in cloth for 10 to 15 minutes at a time during the first 24 hours
After 24 to 48 hours, use a warm compress for 10 to 15 minutes at a time
Gently massage the area around the hickey, not aggressively
Use arnica gel or vitamin K cream if available
Cover it with makeup or concealer
Wear clothing or accessories that hide the area
Avoid rubbing, scratching, or pressing hard on it
Seek medical advice if it is very painful, swollen, or not improving
