Summer Skincare Recommendations for Nutrition and SPF Products

Skin Damage From the Sun
The ultraviolet
radiation from the sun can cause free-radical damage to the skin. Free-radical damage occurs when there is an
imbalance between harmful reactive oxygen and the amount of anti-oxidants
(chemicals which allow the body to stop free-radicals). A free-radical is defined as a molecule that
has an unpaired electron. This makes the
molecule unstable. A free-radical will
always search for an electron to unite with to “make it whole”; so it will
borrow an electron from, say, beta-carotene. Then beta-carotene borrows an electron from Vitamin “C”, which will
borrow an electron from Vitamin E, and so on. If we didn’t have anti-oxidants, the free radical damage could unravel
all of our cell membranes, fracture our DNA, and cause collagen to break
down. Our skin then can appear saggy,
wrinkled, and can develop skin cancers. Have you noticed a slower turnover of dead skin cells, or more brown spots? Some of this is due to lack of anti- oxidants
in the skin.
Diet and the Skin
The skin uses multiple
dietary nutrients to protect itself. For
instance, there are different types of anti-oxidants; Coenzyme Q10,
glutathione, Vitamin C, alpha lipoic acid, as well as more complex molecules
such as catalase, glutathione peroxidase, etc. Exposure to UV light, aging, chronic chemical exposure from our
environment, and too much sugar will deplete these naturally occurring
anti-oxidants from the skin. If we get
low on anti-oxidants, there are actually studies showing that the body will
prioritize their distribution according to the need. Therefore the anti-oxidants you eat may be
sent to your kidneys instead of your skin if you don’t have enough around to
cover all areas where they are needed!
Did you know that
Greece (yes, sunny Greece) has one of the lowest rates of melanoma (the most
aggressive type of skin cancer), and Australia has one of the highest? Could diet be the difference? Diets high in fruits and vegetables are most
protective, while diets high in alcohol, red meat, fries foods, and butter
allow for significantly more UV associated sun damage. Note: our red meat is now corn fed with
genetically modified grain, and has lower omega 3 content. Grass
fed, organic, and free range meat and dairy products will be more nutritious.
Nutritional Recommendations to Minimize Sun Damage:
·
Beta-carotene - specifically reduces melanoma
risk, and works with Vitamin A, C, and E for a multiplier effect. Sources include: carrots, sweet potatoes, kale, pumpkin,
spinach collard greens.
·
Lutein and Lycopene (fellow carotenoids) protect
cells against both free-radical damage and genetic damage. Dietary sources of lutein include: spinach, kale, peas, brussel sprouts,
zucchini, pistachios, broccoli, and corn. Lycopene is of course found in
tomatoes. One study found that an oral
lycopene supplement reduces the count of sunburned cells by 83%, as compared to
people who took no lycopene and had the same duration of sun exposure.
·
Flavanoids and polyphenols are anti-oxidants
that come from green tea, black tea, caffeine, cocoa, grape seeds, grape skins,
and citrus peels.
·
Black tea and green tea protect against UVB
tumors, and a component of green tea called “ECGC” reduces the frequency of DNA
damage to fibroblasts (the cells which make collagen in the skin) that are exposed to
both UVA and UVB over time. So drink your green tea!
·
Citrus peel flavanoids (Oranges, limes, lemons)
protect against squamous cell carcinoma.
·
Resveratrol inhibits skin cancers produced by
UVA light.
·
Vitamin C helps preserve stores of your more
potent anti-oxidants such as glutathione, reduces UV redness, and protects your
DNA from UV damage.
·
Vitamin E (mixed tocopherols) protects against
UV-induced sun damage to the fats in all of your skin cell membranes.
·
Fish oil is an omega 3 fat that supports immune
function to fight cancer, important because UV radiation can induce suppression
of the immune system.
·
Olive oil is an Omega 9 fat that slows signs of
skin aging and protects against skin cancers.
At Alternatives we have two supplements
available containing many of the anti-oxidants and nutrients described above:
Sunpal and Tanpal. Sunpal is a multi-vitamin to take throughout the summer and Tanpal offers additional support for activities in the sun.
Formulated by Dr. Jonathon Wright and based on research featured in the American Journal of Clinical Nutrition and Nutrition Reviews, these supplements are an option for a simple way to give your skin
the nutrition it needs to help protect it in the summer months. Keep in mind these supplements go hand in hand
with a healthy diet!
What About Vitamin D?
Vitamin D is first
formed in the skin. When exposed to the
sun, the body uses cholesterol in the skin to make Vitamin D1. The liver then converts Vitamin D1 to Vitamin
D2. The kidney converts Vitamin D2 to
Vitamin D3 which is the ACTIVE FORM. There is a documented deficiency of Vitamin D3 in all areas of
the United States -sunny or not!
There are multiple
theories as to why Americans are deficient in Vitamin D3. The prevailing theory
is that we are over-utilizing sunscreens or not getting enough sunlight. This may be true, but it is not the full
story. I have checked Vitamin D3 levels on many tanned individuals exposed to
plenty of sunlight who are still deficient in Vitamin D3.
What might be some
other explanations? We need to consider
that many people are on cholesterol lowering drugs, and they may not have
enough cholesterol available in their skin to produce enough Vitamin D1. Another possibility is that the cholesterol
in the skin gets damaged by the UV light and thus is not available to be turned
into Vitamin D1 (not enough anti-oxidants?)
We should also examine
our liver and it’s ability or lack thereof to convert Vitamin D1 to Vitamin
D2. There are enzyme systems in our
liver that are used to remove toxins from our body. It is possible that the same liver pathway
that is needed to convert Vitamin D1 to Vitamin D2 may be being used to remove
chemicals such as herbicides, and pesticides. It may be that these pathways are overwhelmed and cannot do their jobs (it
turns out that the liver needs anti-oxidants to perform this function). In
other words, perhaps some environmental toxin requires the same enzymes in the
liver to process them that would usually be used to convert Vitamin D to its
active form.
Needless to say there is
more to the story of vitamin D3 that we need to further understand. What we do know is that Vitamin D3 provides
essential functions in our body such as cancer prevention and bone health. For now, we should all supplement with
Vitamin D3 and support our body with wonderful anti-oxidants. Since our body utilizes the sun to make the
hormone Vitamin D, perhaps our Creator designed us to be in the sun -- at least
some of the time!
Recommended Sunscreens
Sunscreens keep you
safe from sunburn, but do they keep you safe? Are all sunscreens the same? Are
there differences in sunscreens that we should be aware of?
SPF (sun protection factor) works by
absorbing, reflecting or scattering the sun's rays on the skin. The
Environmental Working Group said consumers should not purchase sunscreens with
SPF greater than 50. "It is very misleading to put high SPF numbers on
labels because it gives consumers a false sense of security and doesn't offer a
lot more protection," Leiba said. They are right. While SPF 85 may sound
like a lot more protection than SPF 30, the higher the number doesn't always
give a high return. Studies show that sunscreen with SPF 15 can block about 93%
of all incoming UVB rays. SPF 30 blocks 97%. SPF 50 blocks 98%.
Various chemicals are
added into some sunscreens which are actually toxic to your body. There are
also “nano” or minute forms of otherwise non toxic substances that due to their
size are now toxic once absorbed into the skin along with the heat and rays
from the sun.
According to Dr. Mercola, some chemicals to avoid are:
- Para amino benzoic
acid
- Octyl salicyclate
- Avobenzone
- Oxybenzone
- Cinoxate
- Padimate O
- Dioxybenzone
- Phenylbenzimidazole
- Homosalate
- Sulisobenzone
- Menthyl anthranilate
- Trolamine salicyclate
- Octocrylene
- dioxybenzone
oxybenzone
Many sunscreens contain these chemicals, which are toxic to our
skin and overall health. The Environmental Working Group has put together a
"hall of shame" on their website of products to avoid and why. If you have children check out this list as some children's sunscreens contain hormone disrupting chemicals. At Alternatives we have carefully selected skincare
products that have a minimum amount of toxic chemicals or none at all and yet still offer superior
sun protection compared to commercial sunscreens that contain high amounts of
toxic chemicals.
Here are our some of our favorite SPF products:
