What does the skin do?<\/h2>\n

The skin protects the body, limits water loss, supports sensation and helps regulate temperature. Its two main layers are the epidermis and dermis; subcutaneous tissue lies beneath them.<\/p>\n

What does the epidermis do?<\/h2>\n

The epidermis is the outer epithelial layer. Its surface stratum corneum is an important part of the protective barrier. The epidermis has no blood vessels; the vascular network lies below it in the dermis.<\/p>\n

The epidermis is not identical across the body. Thick skin on the palms and soles has an additional clear layer that is absent from most hair-bearing areas. Skin in different locations therefore needs to be considered in context.<\/p>\n

Why does the dermis matter?<\/h2>\n

The dermis is connective tissue beneath the epidermis. It contains collagen, blood vessels, nerves, hair follicles and glands. These structures contribute to support, nourishment and sensation.<\/p>\n

The dermis and subcutaneous fat are not the same tissue. When discussing a device\u2019s action, clarify which tissue is involved and what outcome is expected.<\/p>\n

What is subcutaneous tissue?<\/h2>\n

The hypodermis is fat and connective tissue beneath the dermis. It is structurally distinct from the epidermis and dermis.<\/p>\n

Why does this matter when choosing a procedure?<\/h2>\n

Surface appearance, the skin barrier and deeper tissues involve different questions. \u201cDeep action\u201d alone does not explain the purpose of a particular device. Discuss the concern being addressed, expected benefit and potential risks with a qualified professional. Technical specifications cannot replace individual assessment.<\/p>\n
