πŸŽ“ Dermis & Hypodermis: Second and Third layers of skin


#1

Dermis

  • The dermis is located underneath the epidermis, supporting it with nutrients and oxygen.
  • Dermis consists of blood vessels, sweat glands, hair follicles, sebaceous glands, collagen and elastin fibers, nerves.
  • Collagen give skin strength, elastin give skin elasticity. These fibers get damaged with aging, making skin appear loose, thin, and wrinkled.
  • There is data to support oral consumption of collagen may have a beneficial effect on skin physiology:
  • Sebaceous glands are found all over the body except for palms, soles, and tops of feet.
  • The largest concentration of sebaceous glands are in the face and scalp.
  • Sebaceous glands are the sites of origin for acne and other skin disorders.
  • Sebaceous glands produce sebum, which are oils consisting of triglycerides and fatty acid breakdown products, wax esters, squalene, cholesterol, and cholesterol esters.
  • Sebum gets to the skin surface through pores, lubricating it a protective layer to prevent water loss, and contains antioxidant, antibacterial, and inflammatory properties.
  • Nerve endings are located in the dermis, and this is where we actually feel touch, pressure, pain, and temperature.

Hypodermis (Subcutaneous layer)

The primary function of this fatty layer are to:

  • Protect the organs
  • Provide protection against the cold
  • Energy storage

The results of this study sound promising. But this is confusing, β€œAt the end of the study, skin elasticity in both CH dosage groups showed a statistically significant improvement in comparison to placebo. After 4 weeks of follow-up treatment, a statistically significantly higher skin elasticity level was determined in elderly women. With regard to skin moisture and skin evaporation, a positive influence of CH treatment could be observed in a subgroup analysis, but data failed to reach a level of statistical significance.” I thought the purpose of the study was to develop statistics?
