Great Summer Skin: Inside & Out
Antioxidants
It's official, taking Vitamin C on its own may not be enough to protect cells from photo damage. Reserchers at Cornell University found
that Vitamin C was responsible for only a small portion of the antioxidant activity of apples and that most of the activity came from the
phytochemicals found in apples. Just as we need antioxidants to protect ourselves from free radical damage, so do plants. Many plants
are exposed to strong sunlight all day long and they have evolved clever mechanisms to protect themselves. One of these mechanisms is
the production of phytochemicals which are highly active plant chemicals found in pigments of leaves, fruits, barks, seeds and flowers.
These pigments are also responsible for the colourful variety and rich colours found in nature so the clue is the brighter the colour –
green, red, yellow, orange or purple, the better. A new study by German scientists show that taking an antioxidant supplement may contribute
to the sun protective action to the level of SPF 3 by their skin protective and preventative action. Although you will still need SPF
protection during sunbathing taking antioxidants will increase protection.
Topical Protection
But do antioxidants help when applied topically? Studies suggest that applying antioxidants topically is the only way to deliver high
concentrations on the skin. Topical application of Vitamin C & E can increase skin concentrations by a factor of 10 or 20 and therefore
better equipped to fight and reverse free radical damage. Research also indicates that antioxidants and phytochemicals act mainly in the
dermis while retinoids such as Rose Hip Oil or Pro Vitamin A (betacarotene) act primarily in the dermis.
