Seborrheic Melanosis (SM) is the darkening of the skin in seborrheic areas in darker-skinned individuals. It appears to be a form of post inflammatory hyperpigmentation.
There is localized darkening on some seborrheic areas of the face, namely, the alar grooves, angles of the mouth and labiomental crease.
Typical treatments for seborrheic dermatitis are in order including medicated shampoos (lather the area), mild topical steroids and tacrolimus ointment 0.1% (less effective is pimecrolimus 1% cream). Some patients reported a beneficial effect of treatment with ketoconazole cream.
