Sebum, the oily substance produced by sebaceous glands in the skin, is typically yellowish.
While sebum can appear different under certain conditions, like blackheads (appearing black due to oxidation), it's naturally yellowish. This is confirmed by various sources:
- Cleveland Clinic: "... color — typically, gray, light brown or yellow."
- Ducray: "Sebum is a lipidic substance of yellowish color."
- Medical News Today: "Sebum is a yellowish, oily substance."
- Reddit: "... sebum colors were classified as red or white." This suggests sebum can be red or white under specific circumstances but doesn't negate its base yellow color.
