Stargate has been around for years now and the characters have developed, and aged, along with the show. At the end of the last series Teal'c was looking relatively hunky in a battleweary way (link).
Now it seems he is meant to look younger and glossier. Some idiot (presumably) decided this can be achieved with the use of contouring highlighter and by overplucking his manly eyebrows into an incredibly thin black line.
Poor sod looks a bit of a ducky.
At least they only make him wear the lipgloss for photos.
