Recipe for Sunscreen and After-Sun

(forwarded message from another group with recipes)

Natural Sunscreen

step 1 Materials

You'll need the following ingredients to make sunscreen:8oz carrier. oil -
olive, sunflower, jojoba, soybean - your choice1oz emulsifing wax
Sunblocking
agent - zinc oxide or titanium dioxide - available onlineEssential oils of your
choice (opt.) - I used geranium and sweet orangeThe following tools make the job
easier:Mixer - either handheld mixer, submersible blender, …


step 2 An Easier Recipe

If you want your sunscreen NOW, and you don't want to mess around with making
your own lotion, just buy your favorite lotion from the store, and add your zinc
oxide or titanium dioxide to that!

This means you can make sunscreen that's
sensitive enough to use on delicate skin, or is already your favorite scent or
creaminess.8oz lotionZinc oxide or titanium dioxide (see …

step 3 Mix oils and wax

Measure one ounce of wax into a microwave safe container. Melt on high heat
(approx 1 minute for me). Add 8oz. oil, and blend well.
Add a few drops of
essential oils for scent.The mixture may need to back in the microwave for a bit
if it starts to harden up again.


step 4 SPF Table

Use the following table to determine your measurements.For example, 8oz.
(weighed) of lotion + .8oz of titanium micronized dioxide (weighed) = SPF20+The
Micronized TD is 10% of the original amount of lotion used (not the finished
weight).
If you used 8oz of lotion + .8oz of Micronized ZO, the SPF would be
11-12.


step 5 Add dry ingredients

Wearing your gloves and mask, carefully measure zinc oxide or titanium oxide
into your blending container (see chart above). For this recipe, I weighed out
.9oz of Micronized TO to make an SPF 20.Add the wax/oil mixture to the
powder.
Blend thoroughly.Scrape the sides of your mixing bowl and blend some
more.Continue blending until the powder is thoroughly incorporated.


step 6 Transfer into container

Use a silicone spatula to transfer your mixture into a pastry bag or plastic
baggie with the corner snipped off.Squeeze the lotion into your new containers
and label.Apply liberally and frequently!!


step 7 Disclaimer

These recipes and instructions are for homemade use only. The concentration of
TD/ZO in the lotion is approximated for ease of use. The variations in
concentration will still fall within the SPF ranges set forth, and should not
cause concern in small batches (approx 8-12oz)If you want to make and sell a
skin care product, you must adhere to the regulations set forth by…


step 8 An Alternative

In response to a lot feedback I've been getting, I'd like to offer a TD/ZO
alternative.I haven't tested this out, but this is a recipe I found on Suite
101.
Natural Protection Cream Recipe
3 tbsp.
unrefined sesame oil1 tbsp. unrefined avocado oil1 tbsp. unrefined jojoba oil1
tbsp. walnut or almond oil1 tbsp. shea butter2 tbsp. cocoa butter.


A Good Aftersun is:


4 oz sweet almond oil
4 oz olive oil
1 oz beeswax
2 large tablespoons of honey
10 drops peppermint oil
10 drops tea tree
10 drops lavender
1 large table spoon aloe vera

Melt the beeswax in a double boiler and warm the olive/almond oil. Mix in with
the beeswax and take off the heat . Add the honey and aloe vera and mix well
with a hand blender.
Keep mixing as you add the essential oils then pour into a sterilised jar and
keep in the fridge.

Happy sunny days

The best protection comes from the inside.
By removing the potential for inflammation and replacing it with the means to resolve inflammation you change the whole inflammatory environment.

The potential of omega-3 fatty acids in the prevention of non-melanoma skin cancer.
In toto, there is strong circumstantial evidence from both experimental and clinical studies to support a role for omega-3 FA in the prevention of non-melanoma skin cancer (NMSC).

In experimental animal studies there is direct evidence that dietary omega-3 FA inhibits ultraviolet radiation (UVR) carcinogenic expression, with regard to both increased tumor latent period and reduced tumor multiplicity.

Equivalent levels of omega-6 FA increase UVR carcinogenic expression.
Dietary omega-6 FA increases prostaglandin E synthase type 2 (PGE(2)) level.

Dietary omega-3 FA significantly reduces the inflammatory response and sustains, or enhances, the delayed type hypersensitivity immune response in mice when compared to an equivalent dietary level of omega-6 FA.

Supplementary omega-3 FA significantly increases the UVR-mediated erythema threshold in humans.

Supplementary omega-3 FA significantly reduces the level of pro-inflammatory and immunosuppressive PGE(2) levels in Ultraviolet B-irradiated human skin.

Dietary omega-3 FA dramatically reduces the plasma and cutaneous pro-inflammatory and immunosuppressive PGE(2) levels in mice.

Melanoma growth is reduced in fat-1 transgenic mice: Impact of omega-6/omega-3 essential fatty acids Full text online but similar story. Conclusion, this study, using fat-1 transgenic mice, has demonstrated an antimelanoma effect of n-3 fatty acids and identified a potential PGE3-PTEN pathway for their action.

As we know once omega 6 omega 3 ratio is above 5<> 1 extra omega 6 displaces omega 3 from it's position in the cells the only long term successful strategy is to REDUCE omega 6 intake. Increasing omega 3 intake will help change circulating levels and is required to ensure adequate omega 3 is available but the job of actually replacing the omega 6 in cells with omega 3 can only be accomplished if the ratio of omega 6 is brought down to below 5 omega 6<>1omega 3

Having pointed out the importance of reducing omega 6 intake by eliminating sources of industrially made soy, sunflower, safflower and corn oils and all commercially made foods that contain them I should perhaps also give an indication of the AMOUNT of omega 3 necessary to change the immediate potential for harm.
Effect of n-3 Oral Supplements on the n-6/n-3 Ratio in Young Adults
Epidemiological studies show that n-6/n-3 polyunsaturated fatty acid (PUFA) ratios have risen dramatically in Western diets and are associated with numerous chronic inflammation-related diseases.

More balanced ratios are linked to less inflammation.

This study examines the effects of adding oral supplements containing n-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to diets of healthy young adults on plasma n-6/n-3 ratios.

Thirty volunteers are randomly assigned to one of two groups: experimental group, EPA (1.6 g/day) and DHA (1.2 g/day); and the control group, mineral oil (2.4 ml/day).

Plasma fatty acids, nutrients from foods, and anthropometric measures are evaluated at baseline and at the Week 4 endpoint.

The mean (±SD) n-6/n-3 ratio for the experimental group is significantly lower (6.3 ± 1.6) than the placebo group (16.8 ± 3.5) by study completion.

The results suggest that more balanced n-6/n-3 ratios may be achieved efficiently in healthy, young adults with supplements containing EPA and DHA.
This study shows a measurable difference is found after 4 weeks. But it is likely that the improvement will continue for as long as there is a high ratio of omega 3 available. The rate of cell turnover, the natural renewal and replacement of cells is a slow process. Perhaps 2 yrs will see 50% of cells back to the kind of omega 6 <>omega 3 ratio humans evolved with and it could take 5 yrs of omega 6 avoidance and higher omega 3 availability to see the job finished.
~But the good news is the sooner you start the less likely you are to get sunburnt and it's sunburn that triggers the UV damage that leads to skin cancer development.
To provide the 1.6g/d EPA used in the above paper you will need a concentrated fish oil source such as Nature's Answer, Liquid Omega-3, Two teaspoons daily would provide 1.6g EPA but only 1g of DHA. but it's pretty close and reasonably cheap.
If you can't bear the taste of liquid fish oil then maybe These Natural Factors, RxOmega-3 Factors, EPA 400 mg/DHA 200 mg, would do the trick It would take 4 daily to obtain 1.6g EPA + 0.8g DHA. again a bit short on the DHA These would be better when back in stock at Iherb or maybe if you live in the USA you could find them on Amazon, Vitacost or Swansons or similar. Code WAB666 saves you $5 at IHERB.

Toxic Ingredients in Sunscreen

Watch out for toxic ingredients in sunscreen

by David Gutierrez, staff writer

(NaturalNews) The majority of sunscreens are toxic, environmental groups have warned.

"You want to look out for sunscreens with oxybenzone," said Jane Houlihan of the Environmental Working Group.

Research has implicated oxybenzone as a likely carcinogen, as well as a chemical that is probably absorbed into the body.

Another concern is spray-on or powdered sunscreen.

"When you spray a sunscreen, or you're using a powder sunscreen, you're very likely inhaling small particles and that may or may not be safe," Houlihan said.

And while you can hold your breath while applying such sunscreens, it may be safer to forego them entirely.

A seal from the Skin Cancer Foundation does not mean that a sunscreen is safe either, EWG warns, as the foundation will place its seal on any sunscreen that has an SPF rating higher than 15, or on the product of any company that donates $10,000.

EWG recommends using sunscreens made with titanium dioxide or zinc oxide, which are believed to be less dangerous than newer chemicals.

Unfortunately, warns Friends of the Earth, the majority of such sunscreens are made with nanoparticles -- particles 100,000 times smaller than the width of a human hair. Because particles of this size behave in fundamentally different ways than they do on the more familiar, macro-scale, even a safe metal may be unsafe on the nanoscale.

Evidence suggests that nano-sunscreens are in fact dangerous. Friends of the Earth cites studies showing that nanoscale zinc oxide can kill colon cells and brain stem cells, as well as penetrate the skin and travel throughout the blood and urine. The group also cites studies linking nanoscale titanium dioxide to genetic changes, Alzheimer's disease, autism and epilepsy. Nanoparticles have even been observed to cross the placental barrier in pregnant mammals.

"These nanomaterials are being added without appropriate labeling or reliable safety information, so the public has no way of making informed purchasing choices," Ian Illuminato of Friends of the Earth said.
