Chris Duncan, the Scottish UFC lightweight known as The Problem, has a quote beneath his throat, a winged heart across his chest and two distinct sleeves. The right arm mixes illustrated figures and red accents; the left combines a face, flowers and a geometric pattern.
The quote tattoo beneath his throat

The line below Duncan’s throat reads, “Every man dies, not every man really lives.” It follows the curve of his collarbones, above the feathered chest design. His necklace crosses the middle in this close photo, but the sentence remains readable.
The words speak for themselves; the photos don’t say when he got the tattoo or what prompted it. They’re also separate from “Beautiful Addiction,” the lettering woven into the heart design below.
The winged heart tattoo across his chest

A fight photo against Charlie Campbell shows an anatomical-style heart centered on Duncan’s chest, with wings spreading toward his shoulders. Dark contours and feather details make it much larger than a simple heart outline.
“Beautiful Addiction” appears on ribbon-like shapes below the heart, though the angle hides part of the wording. Small stars sit farther out on the chest. The images show the design, but not Duncan’s personal reason for choosing these symbols.
The red accents in his right-arm tattoo

Duncan’s right-arm sleeve combines dark illustrated shapes with red accents. The photo against Omar Morales shows red forms around the shoulder; another view reveals a helmeted, warrior-like figure and flowers along the inner forearm.
The colors and subjects vary down the arm, rather than forming one repeated pattern. The glove covers his hand in the fight photo, so it doesn’t establish whether the ink continues onto his fingers.
The patterns on his left-arm tattoo

In the exchange with Yanal Ashmouz, Duncan extends his left arm and shows a stylized face on the upper arm, a flower nearby and a tight, repeating pattern on the forearm. The pattern forms a lattice of small shapes, quite different from the curved flowers on his other arm.
The face is clearer in the flag pose below, but its identity isn’t confirmed. The same view shows “Beautiful Addiction” more fully across the ribbons below the heart.
How his chest and sleeve tattoos fit together

Duncan’s raised-arms pose gives the clearest view of the chest and both inner forearms. The heart sits between the wings, with “Beautiful Addiction” below and the longer quote above. His face is painted blue here; that’s face paint, not a tattoo.
The right sleeve has the helmeted figure and red accents, while the left has the face and lattice-like pattern. A necklace and the flag behind him overlap parts of the view, but the main shapes remain easy to distinguish.
Scotland, training and life in the cage
Duncan appears with a Scottish flag in several of these photos. Before the London event in March 2025, he spoke in a UFC interview about training at American Top Team in Florida. That’s useful background, but it doesn’t make each flower, wing or red mark a national symbol.
