Hickey Help!

My bff pointed it out. In ten minutes it went from this

To this

Babe and I made out last night. Could it really have taken all night to get that dark??

And how do I get rid of it lol

Edit:

I forgot I posted this. Babe said the same about the chapstick top. I used a small body spray top then applied a heating pad for awhile. It seems to have helped

I just did the top on the remaining spots so we’ll see

How can hickeys be dangerous?

Thanks for the suggestions. You ladies are awesome!
