What is the layer found below the dermis called?

1. Epidermis

2. Subcutaneous

3. Dermis

4. Corneum

The correct answer is: Subcutaneous

The layer found below the dermis is known as the subcutaneous layer. This layer, also referred to as the hypodermis, primarily consists of loose connective tissue and fat. Its main functions include providing insulation, cushioning for underlying organs, and allowing for mobility of the skin over underlying structures. The subcutaneous layer plays a crucial role in connecting the skin to the underlying fascia and muscles, acting as a supportive base. Understanding the structure of the skin is essential in cosmetology, as it helps professionals appreciate how treatments and products penetrate the skin and their effects on different skin layers. The epidermis is the outermost layer, while the dermis lies directly beneath it, making the subcutaneous layer the appropriate answer regarding its position relative to the dermis. The other terms relate to different layers or parts of the skin. The epidermis is the outer layer of the skin, the dermis is the middle layer responsible for strength and elasticity, and the corneum refers to the stratum corneum, which is the outermost part of the epidermis. Understanding these distinctions is vital for effective skincare and treatment approaches in cosmetology.
