Good News! There are three anti-aging treatments are proven clinically effective:
1) the topical application of retinol;
2) carbon dioxide laser;
3) injection of hyaluronic acid, a moisture-retaining acid that occurs naturally in the skin.
Coming from a family and era of sun worshipers I’ve shied away from the sun over the past few years. Considering where my hubby and I’ve lived for the past eight years, it’s quite a contrast.
In my mid-30’s I tried Retin-A for about six months until I realized I was way too young to see any difference. Now…I’m not but I also don’t live in a climate where I can use something that makes me so sensitive to the sun so…I rely on Mother Nature, good genes (not jeans), and MacDaddy sun block. (This is what my friend, Sheri, calls SPF 75.)
What I’ve found from the Archives of Dermatology is that the hands, face, neck and upper chest all suffer more than unexposed skin, and light-pigmented people wrinkle more readily than others. This damage is essentially an accelerated version of chronological aging. And, ultraviolet radiation from tanning beds induces production of the same enzymes that degrade collagen with age.
Each anti-aging treatment depends on the same mechanism, the interaction of skin cells called fibroblasts with the collagen they produce.
Topical application of retinol, a form of vitamin A, was the first to be proved useful. Although the molecular pathways are not well understood, retinol causes new collagen to form in chronologically aged skin and in skin damaged by ultraviolet light.
Skin creams with retinol are available over the counter, but many do not indicate the concentration of the active ingredient.
Carbon dioxide laser resurfacing, the healing wound produces more collagen after the laser removes thin layers of skin without damaging surrounding tissue.
Injecting a form of hyaluronic acid, similar to a substance the skin normally produces, into the dermis that underlies the wrinkles is the third proven form of anti-aging treatment. This was originally designed as a space filler, with no intended physiological effect. But as the injection stretches the dermis, the fibroblasts respond by producing more collagen and less matrix metalloproteinase, or MMP. There have been studies that have demonstrated that increased collagen production is visible within a month after the injection. The benefit lasts about six months.
Do the benefits of these treatments outweigh the risks?
