The buildup of interstitial fluid between cells in the skin is known as?

The buildup of interstitial fluid between cells in the skin is known as edema. This condition occurs when excess fluid accumulates in the spaces between cells, often leading to swelling in the affected area. Edema can result from various factors, including inflammation, injury, or changes in blood flow, and is an important concept in both the understanding of skin conditions and in the practice of electrolysis, as it can affect skin sensitivity and healing.

Erythema refers to redness of the skin caused by increased blood flow to the surface, often due to inflammation or irritation. Hyperemia is similar in that it also involves increased blood flow, but specifically refers to a more general condition of engorgement of vessels which can lead to redness in tissues. Cellulitis, on the other hand, is an infection of the skin and subcutaneous tissues that can cause redness, swelling, and warmth but is distinct from edema because it involves inflammation and infection rather than just fluid accumulation. Understanding these distinctions helps practitioners assess skin conditions effectively.
