Skin Health Flashcards
Factors that impact skin health
Genetics
Lifestyle
Medical issues
Aging is a ______ and it affects _____ and impacts what
Aging is a natural process and affects metabolism and impacts how the body functions (and skin’s appearance)
Two categories of aging
Extrinsic aging
Intrinsic aging
Extrinsic aging def
External environment; air pollution, smoking, sun exposure, and poor nutrition
Intrinsic aging def
Inevitable physiological; dry skin, wrinkles, gradual dermal atrophy
Photoaging caused by and is estimated what percent of aging
Caused by cumulative UV exposure
Estimated 80% of facial aging
UV light damage effects
Damages elastin and collagen fibers over time; causes the skin to age, stretch, and lose resilience
Smoking effects
Increases wrinkling and discoloration; reduces blood flow
Causes elastosis
Elastosis def
degeneration of elastic fibers and connective tissue leading to loss of elasticity
Chronic alcohol overuse can make what worse
Color, tone, + existing skin conditions (like rosacea) worse
Chronic alcohol causes what and increases what
Causes dehydration in the body
Increases vasodilation (widening of blood vessels) (can lower blood pressure)
Both smoking and alcohol intake can affect
Vitamin levels (vitamin c); blood circulation, compromising general health of skin; potentially increases rate of aging
Pollution effects
Cumulative effects of pollution particles can cause long-term oxidative damage to skin and body
Air pollutants include
Polycyclic hydrocarbons
Volatile organic compounds
Ozone + particulate matter
Skin w/out aging factors
Smooth texture, some sagging and moderate wrinkles, but no photoaging signs
Hormones affects
Metabolisms, cardiovascular health, bone, brain function, sleep, growth, reproduction, + immunities
3 sex hormones
Estrogen
Progesterone
Testosterone
Hormone changes cause
Biochemical reactions that produce skin changes like dryness, increased discoloration, + inflammation
Hormone replacement therapy is used to
Treat hormonal imbalances
Phytoestrogens are what and should not be used as what
Plant molecules that mimic estrogen in the body and should not be used as an HRT replacement w/o health practitioners assessment
