Serotonin Molecule Linework

Description

A fine-line blackwork depiction of the serotonin molecule, featuring the indole ring with a 5-hydroxyl group and an ethylamine side chain labeled HO and NH2. This minimalist design celebrates science and mental health, symbolizing happiness, mood balance, and well-being. Placed discreetly on the inner arm, it reads clearly at small scale and suits a clean, understated aesthetic.
