Which skin condition is characterized by erythematous, scaly rash typically found in specific facial areas?

Seborrhoeic dermatitis is characterized by an erythematous, scaly rash that typically appears in specific areas of the face, such as the nasolabial folds, the scalp, and around the eyebrows. This condition is often associated with an overgrowth of Malassezia yeast, which is normally present on the skin.

The hallmark features of seborrhoeic dermatitis include greasy, yellowish scales and an inflammatory component that results in redness. It can occur in various age groups, including infants (as cradle cap) and adults, often exacerbated by stress, weather changes, and hormonal fluctuations. The location and appearance of the rash are key to distinguishing it from other dermatological conditions.

Understanding this, seborrhoeic dermatitis's presentation is distinctly linked to its specific facial localization and scaly lesions, which fits the question perfectly.
