Pronunciation: [tɹˈuː skˈɪn] (IPA) 
The correct spelling of the phrase "true skin" is /tru skɪn/. Phonetically, this is represented by the IPA symbols for the "t" sound, followed by the "r" sound (made by curling your tongue up and back), the "u" sound (pronounced as in the word "shoe"), the "s" sound, the "k" sound, and the "ɪ" sound (as in the word "bit"), and the "n" sound. This spelling accurately represents the pronunciation of the phrase.
True skin, also known as the dermis or corium, is the layer of skin located beneath the epidermis. It is the thickest layer of the skin and serves as a protective barrier against external influences. This layer is made up of connective tissue and various structural components that support the skin's functions.
The true skin is responsible for providing strength and elasticity to the skin. It contains numerous blood vessels, lymphatics, and nerve endings, allowing for nourishment, waste removal, and sensory perception. It is in the true skin that the hair follicles, sweat glands, and sebaceous glands are embedded, aiding in regulating body temperature and producing natural oils for lubrication.
Furthermore, the dermis is essential for the regeneration and repair of the skin. It contains collagen, elastin, and fibroblasts, which promote the growth and repair of skin cells and contribute to the skin's youthful appearance and elasticity. Additionally, the dermis is responsible for wound healing, as it houses specialized cells involved in the clotting process and the formation of scar tissue.
Overall, the true skin is a vital component of the skin's structure and function. Its complex network of tissues, blood vessels, nerves, and glands plays a critical role in protecting, nourishing, and repairing the skin, ensuring its overall health and well-being.

The term "true skin" is predominantly used in medical and anatomical contexts to refer to the deeper layer of skin, also known as the dermis. The etymology of "true skin" can be traced back to the Old English word "trēowe", which meant "faithful" or "loyal". Over time, the word "trēowe" evolved and was eventually combined with the Middle English word "skin" to form "true skin". The term is used to emphasize the importance and authenticity of the dermis, distinguishing it from the outermost layer of skin, known as the epidermis.
