Natural Botox for Wrinkles: Vitamin C

There are 4 levels of skin aging. Addressing each level of skin aging maximizes your rejuvenation results. The dermis lies just beneath the skin’s surface and is made up of a network of collagen fibers that are linked together much like a chain-link fence. Sun damage and other aging factors act to cause these links to break. The skin loses tone, sags, and fine lines and wrinkles form.

Vitamin C is a powerful anti-inflammatory antioxidant that protects collagen fibers from injury and builds new collagen that, in turn, helps firm the skin, and improve the appearance of fine lines and wrinkles.

Food source: Everyone immediately thinks of an orange as containing the most vitamin C, however, a single serving of a sweet red bell pepper has more than twice the vitamin C and a third of the calories. One half-cup of raw red sweet pepper contains 142 mg of vitamin C and 20 calories. Compare this with one medium orange which contains 70 mg of vitamin C and 62 calories.

Natural Moisturizer for Dry Skin: Omega-3s

Dry skin lacks moisture; that’s obvious. But dry skin also leads to a disruption of the protective ceramide barrier, allowing skin cells to pull apart, moisture to escape, and further dehydration. Restoring the barrier with oils good for your skin can help protect the integrity of the ceramide barrier and reduce the risk of dry skin during the winter. Omega-3s are considered essential fatty acids (EFAs). They are necessary for good health and healthy skin, but the body cannot make them.

Food source: Fish, plant and nut oils are the primary dietary source of omega-3 fatty acids. Dry brittle hair, nails and dry, itchy skin all respond to a diet rich in omega-3s. One of the best places to find omega-3s is lake trout. One fillet of lake trout contains 1567 mg of omega-3 and has 215 calories. Consuming one fillet twice a week helps keep skin moist and protected.
