Getting a serotonin tattoo can be useful both as an individual reminder and as a signal to others who deal with the same problems.

Where should I place my serotonin tattoo?

Compared to some hugely personal tattoo design ideas, most serotonin tattoos look to deploy the chemical compound in tattoo form.

It looks cool when etched on the skin and can be deployed on many parts of the body to good effect. The most common positions for serotonin ink include:

The upper arm
The forearm and inner wrist
The upper chest and shoulder beside the collar bone
The ribs and side
The lower leg

“A semicolon is used when an author could’ve chosen to end their sentence but chose not to. The author is you, and the sentence is your life.” – Amy Bleuel

Much like a serotonin tattoo semi colon tattoos are used in helping those suffering.
