The hypodermis, also known as the subcutaneous layer, primarily functions to insulate the body, absorb shock, and anchor the skin to underlying structures such as muscles and bones.

A - Asymmetrical, B - Border irregularity, C - Color variation, D - Diameter larger than 6mm, E - Evolving size, shape, or color.

Melanin is a pigment produced by melanocytes in the skin that gives color to the skin, hair, and eyes, and provides some protection against UV radiation.

The most common type of skin cancer is Basal Cell Carcinoma.

The hair follicle is located around the hair shaft.

The three main layers of the skin are the epidermis, dermis, and hypodermis.

The dermis provides strength and elasticity to the skin, contains blood vessels, nerves, and various skin appendages such as hair follicles and sweat glands.

Sweat glands help regulate body temperature through the process of perspiration and also play a role in excreting waste products.

The stratum corneum is the outermost layer of the epidermis, providing a protective barrier against environmental damage and preventing water loss.

Melanoma is a more aggressive form of skin cancer that originates in melanocytes, while non-melanoma skin cancers, such as basal cell carcinoma and squamous cell carcinoma, are generally less aggressive.
