Biotin is an essential vitamin that has been grouped with the B-complex vitamins since it was discovered, in yeast alongside other B vitamins.
Although it is technically known as vitamin B7, it is usually simply referred to as biotin. It is currently being marketed for improving nail, skin, and hair aesthetics. There is not much evidence to support biotin's role in this. Biotin's general role is an enzymatic cofactor.
Biotine capsules (water soluble vitamin B) and eucalyptus oil. Both have worked for me.
I have had my tongue pierced for a while now and when you first get it pierced your bar will be long for the swelling it takes up too a month until you can change it but after the first week the pain will go away i recommened ice and popcicels but dairy products make it swell more and give you a chance to get a yeast infection in your mouth as for the marks at the top they will go away with ice and rinse your mouth with biotine it works greAT!!!
