There are 3 skin layers: Epidermis Dermis Subcutaneous layer Skin Anatomy
What is skin aging? • Collagen production slows (skin gets thinner) • Elastin fibers break down (skin loses its ability to snap back after stretching) • Subcutaneous fat decreases (skin looks less plump and smooth) • Turnover of skin cells slows down • Skin becomes dryer
What causes skin to age? • Sun (ultraviolet light)—damages elastin and collagen fibers, causing wrinkles, and producing mottling and brown spots • Cigarette smoking—damages elastin and decreases blood flow to skin • Gravity—pulls on our bodies and with loss of elastin and collagen, causes sagging • Sleeping positions—cause creases • Facial expressions—muscles produce grooves in skin which gradually become etched in face
Prevention of skin aging AVOID ULTRAVIOLET LIGHT!!!!! • Avoid deliberate tanning • Stay out of sun between 10AM and 4PM • Wear protective clothing (hats, long sleeves) • Apply broad spectrum (UVA and UVB) sunscreen (SPF 25 or greater) year round
Treatment of Aging Skin • Products • Fillers and injectables • Peeling and microdermabrasion • Thermage • Lasers • Fraxel • Fractional CO2
Products • Sunscreen • Moisturizers • Tretinoin • Everything else
Injectables and Fillers • Botox cosmetic, Dysport • Zyderm (bovine collagen) • Restylane (hyaluronic acid) • Juvederm (hyaluronic acid) • Radiesse (hydroxyapatite) • Evolence (porcine collagen) • Sculptra (poly-L-lactic acid)
Peels and Microdermabrasion • Light “lunchtime” peels: glycolic, beta, Jessner • Medium depth peels: trichloroacetic acid • Microdermabrasion: high pressure crystals delivered to skin which remove dead skin cells
Thermage • Radiofrequency waves delivered to deeper skin layer which causes tightening of skin • Produces heat in deeper layers of skin while maintaining cool on surface of skin • Little recovery • Not successful in all patients!
Laser • Vascular lasers and intense pulsed light remove tiny blood vessels and brown spots • Q switched lasers (Ruby, Versapulse, Medlite) remove brown spots • Fraxel (fractionated erbium laser) • Fractional CO2 (fractionated CO2 laser)
Intense Pulsed Light Intense Pulsed Light uses different wavelengths of light to target “broken” blood vessels and superficial brown spots. The light energy is changed to heat energy, which gradually fades the targeted pigment or vessels.
Fraxel • Multiple tiny microscopic columns of erbium laser light treat a fraction of the skin at one treatment, making recovery much easier than resurfacing treatments. • Requires multiple treatments • Decreases fine lines, wrinkles, scars and skin blotchiness • Not good for deep lines and sagging skin
Fractional CO2 (Active FX) • Columns of high energy CO2 laser light interact with skin • Only a fraction of the skin’s surface is treated, leaving small “bridges” of untreated skin • Collagen in skin shrinks immediately • Stimulates collagen remodeling over time • Downtime usually less than one week • Single treatment
Fractional CO2 (Active FX) Primary Targets: • Fine lines and wrinkles of the face • Crow’s feet around eyes • Pucker marks (“smoker lines”) and frown lines • Brown spots and blotchy, uneven skin tone • Scars, especially acne scars
