Which skin condition is characterized by red lesions primarily?

Psoriasis is characterized by red lesions that are often covered with silvery-white scales, which distinguishes it from other skin conditions. The lesions typically appear on the elbows, knees, scalp, and lower back, but they can occur anywhere on the body. This chronic autoimmune condition arises from an accelerated skin cell life cycle, leading to an accumulation of cells on the surface of the skin. Understanding this condition is essential for nail technicians, as it can affect nail health and may be present under or around the nails, impacting the services provided.

In contrast, while conditions like cellulitis and dermatitis can also involve redness, they are associated with different symptoms and underlying causes, such as infection or inflammation, and do not typically present the same pattern of lesions as psoriasis. Albinism is a genetic condition resulting in little to no pigment in the skin, hair, and eyes, and does not present with red lesions. Thus, psoriasis is the most fitting answer when identifying a skin condition characterized primarily by red lesions.
