ABNOM is a cutaneous condition characterized by multiple brown–gray to brown–blue macules, primarily in the malar region of the face. It can also occur simultaneously with other pigmentary skin diseases such as melasma, freckles, multiple lentigines and Ota's nevus. Only minimal change is observed in this dark spots, whereas the melasma have become darker and lighter as the continuous pigment production and decrease.

Whitening agents rarely help. Unlike melasma, ABNOM can be improved with laser treatment and left to be removed without recurrence. Laser treatment can be performed 10 to 20 times to treat ABNOM.
