ANTI-AGING Flashcards
(48 cards)
Complex biological process influenced by a combination of endogenous and exogenous factors.
SKIN AGING
Examples of Endogenous Factors:
GENE MUTATION
CELLULAR METABOLISM
HORMONAL FACTOR
Examples of Exogenous Factors:
U.V
POLLUTANTS
CHEMICAL
TOXINS
Structural and physiological alteration of the skin layers.
SKIN AGING
Skin aging is Composed of two processes:
INTRINSIC
EXTRINSIC
• Slow, continuous, and irreversible
tissue degradation.
• Natural result of Aging
INTRINSIC SKIN AGING
• General aging process which occurs
by the passing of time alone.
• Smooth, thin, pale, and finely
wrinkled.
INTRINSIC SKIN AGING
• Thinning of the Dermis due to the reduction of collagen.
• Loss of Skin elasticity.
INTRINSIC SKIN AGING

WORRY LINE
around eyes and mouth
LAUGH LINE
outside corners of the eyes.
CROW’S FEET
• Decrease in immune cell production.
• Gradual flattening of the wavy attachment between the epidermis and dermis due to Reduced production of Keratinocyte.
INTRINSIC SKIN AGING
• Reduction in the SC Lipid content, Damage barrier functions, Increased epidermal Water loss, and Drier Skin.
• Decrease in the density of Melanocyte.
• Increase in the size of Sebaceous glands
INTRINSIC SKIN AGING
• exposure to various environmental
factors (Sun, Wind, Smoking, and Air
pollutants).
• Course skin with wrinkles.
• Hyperpigmented areas
• Sallowness
• Increased fragility
• Textural roughness
EXTRINSIC SKIN AGING

TELANGIECTASIA
Photoaging
aging caused by the sun.
UV RADIATION
Premature aging
great contributor of facial wrinkling
than sun exposure
SMOKING
• has little impact in the skin.
• blocked by the ozone layer.
UVC
• penetrates in Epidermis
• Redness, Sunburn, DNA damage,
hyperpigmentation and Cancer
UVB
• requires higher dose to cause sunburn.
• penetrates deeper in the skin.
• responsible for most chronic skin damage.
UVA
• Increased or decreased Epidermal thickness.
• Loss of Langerhans cells and immune cytokine.
• Increased number and activity of Melanocytes.
• Hypopigmented areas on photodamaged skin.
Degradation of Collagen and Elastin.
EXTRINSIC
accumulation of abnormal elastin.
ELASTOSIS
main ingredients of anti-aging products are often called “______” ingredients
