Lutein, Zeaxanthin, and
Skin Health - Medscape, 6/7/13 - "Results from cell
culture and animal studies showing that lutein and zeaxanthin exhibit positive
skin health benefits have considerable merit and suggest an avenue by which
these carotenoids may function. The results from one human study demonstrate
that orally administered lutein and zeaxanthin can inhibit lipid peroxidation on
the surface of the skin and help bolster the skin's photoprotective activity,
potentially protecting the skin from exposure to light, particularly UV light.
Since the typical diet of people in the United States is about 2 mg of lutein
per day, due to the ingestion of foods such as green leafy vegetables that
contain the highest levels of diet-derived lutein and zeaxanthin, it may be
considered advisable to increase the daily intake of lutein and zeaxanthin for
optimal skin health and photoprotection" - See

omega-3 supplements may help prevent skin cancer, new study finds - Science
Daily, 2/26/13 - "the study analysed the effect of
taking omega-3 on 79 healthy volunteers ... taking a regular dose of fish oils
boosted skin immunity to sunlight. Specifically, it also reduced
sunlight-induced suppression of the immune system, known as immunosuppression,
which affects the body's ability to fight skin cancer and infection ... it was
the first time the research had been carried out on humans" - See

Strawberry extract protects against UVA rays, study suggests - Science
Daily, 8/3/12 - "The team prepared human skin cell
cultures (fibroblasts) and added strawberry extract in different concentrations
(0.05, 0.25 and 0.5 mg/ml), the only exception being the control extract. Using
ultraviolet light, the samples were then exposed to a dose "equivalent to 90
minutes of midday summer sun in the French Riviera." ... the strawberry extract,
especially at a concentration of 0.5 mg/ml, displays photoprotective properties
in those fibroblasts exposed to UVA radiation, it increases cell survival and
viability and decreases damage in the DNA when compared with control cells ...
But what molecules give strawberries their photoprotective properties?
Scientists suspect that it could be the anthocyanins, which are pigments that
give leaves, flowers and fruits their red colour" - See

of facial skin aging and vitamin D levels in middle-aged white women -
Cancer Causes Control. 2010 Sep 30 - "Adjusting for age
and season of blood collection, women with lower photodamage scores were
associated with a 5-fold increased odds of being vitamin D insufficient (OR 5.0,
95% CI: 1.1, 23). Low scores for specific photodamage parameters including
erythema/telangiectasias, hyperpigmentation, and wrinkling were also
significantly associated with vitamin D insufficiency. Our results suggest an
association between skin aging and 25(OH)D levels" - See

Lycopene-rich tomato paste helps skin from within: Study - Nutra USA,
Pomegranate compounds show skin health potential - Nutra USA, 8/10/10 -
"ellagic acid may prevent the degradation of collagen in
human skin cells, which would maintain skin structure and slow the formation of
wrinkles ... Topical or dietary interventions with berries and pomegranate rich
in ellagic acid and ellagitannins are promising strategies in curtailing skin
wrinkling and cutaneous inflammation associated with chronic UV exposure leading
to photoageing" - [Abstract]

Dietary compound ellagic
acid alleviates skin wrinkle and inflammation induced by UV-B irradiation -
Exp Dermatol. 2010 Aug;19(8):e182-90 - "Ellagic acid, a
polyphenol compound present in berries and pomegranate, has received attention
as an agent that may have potential bioactivities preventing chronic diseases
... These results demonstrate that ellagic acid prevented collagen destruction
and inflammatory responses caused by UV-B. Therefore, dietary and
pharmacological interventions with berries rich in ellagic acid may be promising
treatment strategies interrupting skin wrinkle and inflammation associated with
chronic UV exposure leading to photoageing" - See

evidence of skin benefits of a dietary supplement containing probiotic and
carotenoids on UV- induced damage - Br J Dermatol. 2010 Jun 9 -
"Lactobacillus johnsonii (La1) ... dietary
supplement (DS) combining La1 and nutritional doses of carotenoids ... A 10 week
DS intake prevented the UV-DL induced decrease in Langerhans cell density and
the increase in Factor XIIIa+ type I dermal dendrocytes while it reduced dermal
inflammatory cells. Clinical and instrumental MED rose by 20% and 19%
respectively, and skin colour was intensified, as shown by the increase in
DeltaE parameter. The efficacy of DS was confirmed by dermatologists and
subjects in real conditions of use. Conclusion: Nutritional supplementation
combining a specific probiotic (la1) and nutritional doses of carotenoids
reduced early UV-induced skin damage caused by simulated or natural sun exposure
in a large panel of subjects (n=139). Altogether, these results support the use
of this nutritional supplement for a global approach in photoprotection, in
combination with a sunscreen" - See

Antioxidant Study Suggests Possibility of "Sunburn Pill" -
Medscape, 12/11/09 - "The researchers
theorize that people at increased risk for melanoma could take NAC
as a "sunburn pill" before exposure to large amounts of sunlight.
Such an approach, they add, could theoretically reduce a person's
lifetime risk of melanoma and also minimize the problems associated
with taking a daily medication" - See

New Role Of Vitamin C In Skin Protection; Relevance To The Cosmetics
Industry - Science Daily, 9/8/09 - "a
form of Vitamin C helped to promote wound healing and also helped
protect the DNA damage of skin cells ... Previously, the group has
published evidence that DNA repair is upregulated in people
consuming vitamin C supplements ... The results demonstrated that
vitamin C may improve wound healing by stimulating quiescent
fibroblasts to divide and by promoting their migration into the
wounded area. Vitamin C could also protect the skin by increasing
the capacity of fibroblasts to repair potentially mutagenic DNA
lesions ... Free radicals are associated with premature skin aging,
and antioxidants, such as vitamin C, are known to counter these
highly damaging compounds. This new evidence suggest that, in
addition to ‘mopping up’ free radicals, vitamin C can help remove
the DNA damage they form, if they get past the cell’s defences"
Inhibition of UVA and UVB radiation-induced lipid oxidation by
quercetin - J Agric Food Chem. 2009 Jun 24;57(12):5301-5 -
"Quercetin, which absorbs UV radiation at
255 and 365 nm, was determined to be a stronger inhibitor of lipid
oxidation induced by UVB (3.7 radicals scavenged per molecule) than
by lipid oxidation induced by UVA (1.9 radicals scavenged per
molecule). The values for inhibition of UVB-induced lipid oxidation
by quercetin are comparable to those when
2,2'-azobis(2-amidinopropane) was used as an oxidizing system (four
radicals scavenged per molecule). The protective effect of quercetin
appears to be mainly the result of scavenging of UV-generated
radical species, although this may be decreased slightly in the UVA
as a result of its absorption at 365 nm" - See

11/7/08 - "According to LycoRed, subjects
were supplemented by either Lyc-O-Mato capsules (10mg lycopene per
day), or a placebo, for ten weeks. Following exposure to UV
radiation at the end of the study, it was found that subjects in the
tomato extract group had a sunburn cell count six times lower than

New Sunscreen Guide: 1 in 4 Products Deemed Safe - WebMD, 5/15/12 -
"Among the EWG's concerns: ... Poor UVA protection:
UVA rays account for 95% of the sun's radiation. They contribute to skin
cancer and wrinkles. Though the new FDA rules require sunscreens to pass a
test before they can claim "broad spectrum" protection against UVA rays, the
EWG says the new test is so easy to pass that most sunscreens on the market
will make the grade with no reformulation. That's bad news, they say, since
over half the sunscreens they reviewed offer such weak UVA protection that
they would not be sold in Europe, where standards are stronger ... The
danger with sunscreens with SPFs that climb past 50 is that they offer only
marginally better protection than an SPF of 30, and they may lull consumers
into thinking they are better shielded than they actually are. A false sense
of security can lead people to spend too much time in the sun, putting them
at greater risk for burns and skin cancer ... Oxybenzone is an active
ingredient found in more than half of all beach and sport sunscreens. Some
studies suggest the chemical may mimic the hormone estrogen in the body"

"No SPF, not even 100+, offers 100 percent
protection. What’s more, both UVA and UVB radiation can lead to skin cancer,
which is why dermatologists now advise using sunscreens with an SPF of at
least 15 and UVA-fighting ingredients like an avobenzone that doesn’t
