Seborrheic dermatitis is characterized by an oily appearance and is often seen with pinkish-yellow patches on the skin. This condition primarily affects areas of the body that have a high concentration of sebaceous (oil) glands, such as the scalp, face, and upper back. The patches are typically greasy and may be accompanied by flaking or scaling.

The oily nature of seborrheic dermatitis is due to overactivity of oil glands, which can lead to the production of excess sebum. The patchy, reddish-yellow appearance is a result of inflammation and the shedding of skin cells. This condition can easily be mistaken for other skin issues, but its distinct features, such as the oily surface and specific locations where it commonly occurs, help to differentiate it.

While other skin conditions like contact dermatitis, eczema, and atopic dermatitis may display redness and inflammation, they do not typically share the same oily appearance or the distinctive yellow patches that characterize seborrheic dermatitis. Understanding these specific traits is crucial for differentiating between these common skin conditions in skincare practice.
