Healthy Skin Women and Dermatology



Healthy Skin Women and Dermatology
By:Suguru Imaeda, M.D.
Chief of Dermatology, Yale University Health Service

Overview
* Normal structures of the skin
* Changes in the skin over time
* Sun and skin
* Skin cancer
* Maintaining healthy skin
Epidermis
the largest organ
* key role in normal healthy functioning of the body
* Disorders range from those limited to the skin to manifestations in the skin of internal disorders
* plays important role in social and psychosocial functioning of the individual
* undergoes changes with aging and in response to external environmental factors and internal hormonal influences
Gender differences
* Fundamental differences in structure and function of the skin
* Differences impact on presentation of skin disease and its management
* Hormonal influences affect common disorders such as acne, rosacea, lupus erythematosus, psoriasis, lichen planus, anogenital pruritus, hidradenitis suppurativa, and atopic dermatitis
Infancy
Toddler to adolescence
Adolescence
Body piercing
* presents risks for multiple possible complications
* nickel allergy
* secondary infection with staphylococcus or streptococcus
* ear cartilage destruction from pseudomonal infection
* candidal infection of the navel or genitalia
* Keloids
* traumatic tears
Tattoos
* Infection
* Granulomatous reaction
* Photodermatitis
* Difficult to remove
Melasma
* Brown patches on forehead and cheeks
* Very sensitive to sun exposure
* More common in Hispanics, Middle Easterners, and Asians
* Most common cause is oral contraceptive use or pregnancy
Melasma management
* Discontinuation of oral contraceptive
* Avoidance of sun/tanning bed
* Daily application of broad spectrum sunscreen
* 4% hydroquinone or 20% azelaic acid
* ? laser
Intrinsic aging
* Changes of chronologic aging gradually become apparent
* Influenced by genetics, gravity, and hormones
* Clinically, the normal aging process leads to fine wrinkles, dryness, sallow color, thinner skin, laxity and purpura
Aging skin
* Decreased function as environmental barrier, sensory organ and immune organ
* Epidermal and dermal atrophy with loss of appendages
* Decreased sweat production leads to dryness
* Decreased body and scalp hair
* Decreased ovarian estrogen production leads to decreased collagen and increased wrinkling
* Overall thinner, paler, drier, with fine wrinkling and decreased elasticity
Histologically
* dermal thinning
* decreased vascularity
* decreased subcutaneous fat
* reduced cellularity of the dermis
* elastic fiber loss
* dermal thinning
* decreased vascularity
* decreased subcutaneous fat
* reduced cellularity of the dermis
* elastic fiber loss

Environmental factors on skin
* create extrinsic damage
* major effect is from photoaging with wrinkling, laxity (sagging), lentigenes, dyschromia, coarseness, sebaceous hyperplasia, and telangiectasia
* 90% of visible skin changes of aging
* Visible as early as age 20
Smoking
* shown to decrease both hyaluronic acid and glycosaminoglycan synthesis
* causes decreased capillary blood flow in the skin
* changes accelerate wrinkling
The twenties
* Skin is smooth and coloring is even
* Little need for emollients
* Skin care is simple - variety of products are tolerated
* May be persistent acne associated with hormonal activity manifest by flaring during the week prior to the menstrual period.

The thirties
* thinning of the skin beneath the eyes
* skin is less elastic
* Fine wrinkles begin to appear around the mouth and lateral periorbital region
* Increased fat and sluggish blood flow contribute to puffiness and darkening of the skin beneath the eyes
The forties
* More sallow and less supple
* Skin surface not as smooth
* Liver spots, solar lentigenes, appear on areas of chronic low grade sun exposure - face, dorsal hands, back or dorsal feet
* Thin red spider angiomas appear on the legs
* Weight gain leads to sagging skin
* Cellulite appears on thighs and buttocks
* Deep furrows develop on forehead and lateral periorbital areas (crow’s feet)
* Skin becomes drier - sweat glands grow smaller and become less effective
The fifties and sixties
* Wrinkles are deeper - skin begins to sag and droop
* Skin tone is lighter from decreased circulation
* More solar lentigines form
* Collagen and elastin are thinner
* Collagen is estrogen dependent therefore skin is both thinner and drier
* Dryness occurs from thickening of the stratum corneum
* Moisturizers help keep the skin moist and supple
* Alpha hydroxy acid-containing products help by reducing the thickness of the stratum corneum, promoting thickening of the epidermis and dermis, and promoting synthesis of collagen, elastin, protein and glycosaminoglycan
Pregnancy
* rosy complexion - increase in vascular circulation
* hyperpigmentation on the nipples, vulva, anus and inner thighs from hormonal stimulation
* Freckles (ephelids) and birthmarks may also darken
* Melasma, the mask of pregnancy, from hormonal changes, sun exposure and genetic factors
* Skin tags develop on the neck, chest, inframammary area, inner thighs, and face
* Spider angiomas, purpura and capillary hemangiomas
* Stretch marks, striae distensae
* Varicosities and hemorrhoids
Sun protection
* Signs of extrinsic photoaging not intrinsic genetic aging usually prompts the visit to the dermatologist
* Therefore, it is most important to incorporate into the daily routine a sun protection regimen
Tan
* Coco Chanel declares tanning “in” in 1920’s
* Suntan seen as symbol of health, youth, status
* Skin’s reaction to damage from UV radiation
* Melanocytes produce melanin
Indoor tanning
* Increasingly popular, esp among young women in 20’s
* Advertised as safe, “healthy glow”, little risk of skin cancer
* Controlled tanning protects against sunburn by building up melanin
* Vitamin D helps prevent breast, prostate, colon cancer
Dripping faucet
* Your skin = empty glass
* Dripping water = ultraviolet radiation
* Rate of drip = amount of sun exposure
* Rate of evaporation of water = skin’s ability to repair DNA damage caused by UV radiation
* Your glass is full = you’ve reached your limit of sun exposure
* Water starts spilling over the top = getting skin cancers
Ultraviolet radiation
