- Avoid exogenous radical generation from midday sunlight and smoking.
- Scavenge the radicals that get through with carotenoids and vitamin E. I aim for about a 6oz can of tomato paste (or sauce equivalents) and tsp of wheat germ oil daily.
- Suppress the inflammatory response to UVA & B, and subsequent superoxide generation and matrix metalloproteinase expression, with fish oil/EPA and high polyphenols (vegetables, fruit esp berries, tea, coffee cocoa, wine, curcumin etc).
- Avoid tissue glycation, from very high dietary fructose and uncontrolled blood sugar. The same diets that prevent diabetes (low in saturated fat and added sugars) or aid glycemic control for diabetics (high-fiber/lower glycemic index starches) should help lower average blood glucose in non-diabetics.
- Monounsaturated fats from plant sources like olive oil, but not animal sources, should be the predominant fat, as its neither inflammatory (as saturated fats are) and is less prone to UV-generated singlet oxygen damage than polyunsaturated fats.
- Supplemental oral retinoids, NSAIDs, fish oil/EPA, and B3 (niacin/nicotinamide) may help.
Collagen turns over, but elastin has to last a lifetime, so MMP overxpression appears to be the crucial event in skin aging. There's a lot of material on MMP expression response to interventions in oncology, its daunting but I plan on getting to it.
