Presentation Transcript

  1. Skin coloration Yellow – back? Bush? Orange?

  2. melanocytes The type of melanin and the level of activity of melanin determine our yellow-black skin tonation.

  3. Blush coloration The blood vessels in your dermis constrict (shrink) or dilate (open) to change the flow of blood to the dermis. This affects the pinkish/reddish coloration of our skin. The lighter (melanin) the skin, the more apparent this coloration.

  4. cyanosis When the blood of the dermis is lacking oxygen, it becomes a bluish hue. Thus the skin takes on a bluish coloration.

  5. Orange tinge If a person eats an excessive amount of carotene (pigment), the carotene may accumulate in the dermis and cause an orangish coloration.

  6. S Skin and the aging process

  7. Vernixcaseosa Babies are born with a protective covering. This protective covering protects them from being bathed in amniotic fluid for 9 months. It goes away shortly after birth.

  8. milia Infants may have overactive sebaceous glands. This results in milia – kind of a form of baby acne.

  9. Adolescent acne

  10. Aging of the skin

  11. UV radiation Exposure to UV radiation over time accelerates aging. It breaks down the collagen and elastin fibers of the extracellular matrix. These fibers are not readily replaced.

  12. wrinkles Loss of collagen and elastin decrease the binding of the dermis to tissue below. There fore is succombs to gravity. This is wrinkles.

  13. Smoking can accelerate the loss of dermal extracellular matrix fibers. Thus accelerate the process of aging – wrinkling.

  14. Subcutaneous tissue As we age our subcutaneous and epidermal layers decrease in thickness. The loss of the stratum corneum causes the skin to dry out faster. It also makes it more transluscent.

  15. The loss of subcutaneous tissue decreases the insulative (heat retaining) property of the skin. We get cold easier as we age.

  16. alopecia Hair bulbs/roots become less active as we age. We lose hairs OR they become finer/shorter.

  17. Gray/colorless hair AS we age the amount of melanin produced in our hair bulb/follicle diminishes. This causes our hairs to become colorless/gray.
