Which term refers to the swelling condition that can occur in skin tissues?

The term that refers to the swelling condition that can occur in skin tissues is oedema. Oedema is characterized by the accumulation of excess fluid in the interstitial spaces, leading to noticeable swelling. This condition can be localized or widespread and may occur due to various factors such as injury, inflammation, or underlying health issues. Understanding oedema is crucial in esthetics as it can affect the skin's appearance and texture, influencing treatment decisions for skin care.

In contrast, sepsis is a severe and potentially life-threatening response to infection, rather than a localized swelling condition. A lesion refers to any abnormal tissue change, which could encompass a wide range of skin issues but does not specifically denote swelling. Dermatitis describes an inflammation of the skin that can lead to a rash and irritation but does not specifically highlight the fluid accumulation characteristic of oedema.
