Mesotherapy for Sun-Damaged and Aging Skin
Cutaneous aging signs of sun-damaged skin become visible from as early as the twenties, especially with excessive sun or environmental exposure. However between the ages of 35 to 49 years, there is a sharp increase in prevalence of skin changes clearly ascribable to photo-aging such as pigmented spots and sun-damaged skin. Awareness of the damaging effect of UV radiation on the facial appearance and sun avoidance and protection before the age of twenty will help reduce the risks for developing sun-damaged skin later in life.
Sun-damaged skin is associated with a range of cosmetic concerns from pigmentation problems and splotchy skin to redness due to enlarged vessels or capillaries, all causing discoloration of the skin. Photo-aging, caused by ultraviolet light exposure, tends to act more on the surface of the skin. There are sun freckles or irregular pigmentation and dilated blood vessels (often referred to as “broken” blood vessels) that lead to an overall uneven tone and discoloration. Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion, actinic keratoses (thick, wart-like, rough, reddish patches of skin), and skin cancer can all be traced to sun exposure. There is increased water loss from the skin and a decrease of the sebaceous glands, which provides natural moisture to the skin. More abnormal cells accumulate in aged skin, especially if there is chronic sun damage, which can lead to pre-cancerous and cancerous lesions.
How does Sun Exposure Age Our Skin?
Scientific studies have shown that repeated ultraviolet (UV) exposure breaks down collagen and impairs the synthesis of new collagen. The sun also attacks our elastin proteins which provides elastic resiliency to our skin. UV exposure also causes chronic inflammation of the skin and an increase of elastin that clusters into thick bundles called solar elastosis. Collagen decreases as we age and the bundles of collagen, which give the skin turgor, become looser and lose strength; thus causing fine lines, wrinkles and sagging.
Mesotherapy for Skin Revitalization
Mesotherapy for skin revitalization infuses the dermal layer of the skin with a potent cocktail of collagen growth factors, vitamins and antioxidants to rejuvenate and revitalize damaged dermal tissues. Mesotherapy treatments induce epidermal growth factor (EGF) to renew the epidermal cells, and fibroblast growth factor (bFGF) to renew the dermal and epidermal connective tissues. As well, mesotherapy increases the fluid volume loss caused by aging and UV damage.
The treatment is usually performed over an initial series of one session per week for 4-6 weeks. Results are then maintained by less-frequent follow-up sessions. No redness, sensitivity, or ‘downtime’ is experienced with mesotherapy treatments as with traditional collagen products such as Retin A or Restylane.
