Antioxidants and Skin
Care
Antioxidant is a popular term in all health care articles. We always
encounter such a term whenever we read or browse health articles in the
papers, books or magazines. Moreover, almost all advertisements and
commercials of beauty and health products always mention antioxidants.
The question to ask ourselves to be able to understand the sudden hype
about antioxidants is to know what it is and what can it do to our body.
Antioxidants are
chemicals that prevent the oxidation of other chemicals.
In
biological systems, the normal processes of oxidation produce highly
reactive free
radicals that can readily react with and damage other molecules which may
continue to damage even the body’s own cells.
Antioxidants play the housekeeper's role, "mopping up" free
radicals before they get a chance to do harm in your body.
Although all the hype
about antioxidants slowing down the signs of aging and promoting skin
rejuvenation do not have a solid scientific basis, most skin experts are
claiming that antioxidant vitamins and minerals can help in our overall
well being by combating the free radicals in our body.
Here are several
antioxidant nutrients which appear the most likely to produce benefits to
your skin.
> Vitamin A or Beta
Carotene.
It has
been discovered that beta-carotene protects dark green, yellow and orange
vegetables and fruits from solar radiation damage and it is thought that
it plays a similar role in human body. Carrots, squash, broccoli, sweet
potatoes, tomatoes, kale, collards, cantaloupe, peaches and apricots are
particularly rich sources of beta-carotene.
> Ascorbic Acid
(Vitamin C)
is a
water-soluble compound that fulfills antioxidant role, among others, in
living systems. Important sources include citrus fruits (like oranges,
sweet lime etc.), green peppers, broccoli, green leafy vegetables,
strawberries, raw cabbage and tomatoes.

Vitamin E is a
principal fat-soluble antioxidant vitamin in the body. It protects
cellular membranes, lipoproteins and other "oily" structures. Skin is
high in unsaturated fatty acids ("oily" molecules especially susceptible
to free radical damage), and can benefit from vitamin E protection (both
oral and topical).
Sources
include wheat germ, nuts, seeds, whole grains, green leafy vegetables,
vegetable oil and fish-liver oil.
> Flavonoids are a
diverse group of plant pigments with antioxidant properties that contain
proanthocyanins and polyphenols that are good for the skin. These
substances are responsible for color in many fruits, vegetables and
flowers. In addition to providing color that attracts insects or animals,
these pigments protect plants from environmental stress. In addition to
being potent antioxidants, some flavonoids have antiallergic,
anti-carcinogenic, anti-viral and anti-inflammatory activity. Over 4,000
flavonoids have been characterized and classified, but only a few have
been researched.
> Coenzyme Q10,
lipoic acid, cysteine and methionine are potent antioxidants. |
