This weird red mark appeared on my face in the afternoon yesterday. Did my skin routine as normal, not gone a day later. Anyone know what it is exactly? Image included

Changes in skin pigmentation can occur for some reasons, including skin pigmentations, pigmentation issues, rashes, and contaminations. An expansion in melanin, for instance, can make earthy colored spots or dim patches show up. Skin contains melanin, which is the shade that gives the skin its tone.
