Here's why it's not a good idea and what actually works:
* What a hickey is: A hickey is a bruise caused by broken blood vessels under the skin. Bruises take time to heal.
* Why toothpaste is suggested (and why it doesn't really work): Some people believe toothpaste's cooling sensation might reduce inflammation or that ingredients like menthol could stimulate blood flow. However, these effects are superficial and won't significantly impact the underlying bruise.
* Potential problems with toothpaste:
* Irritation: Toothpaste can irritate the skin, especially if it's sensitive. This could make the hickey look worse or cause discomfort.
* No real effect on healing: At best, it might offer a temporary cooling sensation, but it won't speed up the healing process.
What actually helps a hickey heal:
* Cold compress: Apply a cold compress (ice pack wrapped in a cloth) for the first 24-48 hours to reduce swelling and blood flow to the area. Apply for 10-20 minutes at a time, several times a day.
* Warm compress: After 48 hours, switch to a warm compress to help increase blood flow and promote healing.
* Gentle massage: Gently massaging the area around the hickey can also help improve circulation.
* Time: Ultimately, time is the best healer. Hickeys usually fade within 1-2 weeks.
* Arnica cream: Some people find that arnica cream, a homeopathic remedy, can help reduce bruising.
In short: Skip the toothpaste. It's unlikely to help and could potentially irritate your skin. Stick to proven methods like cold and warm compresses.
