Protecting your skin from the
sun’s rays is important and natural sunscreens are a fantastic alternative to
traditional chemical sun tan lotions. After all, your skin is your body’s
largest organ, tasked with protecting your insides from the harsh elements of
the outside world and eliminating toxins from your body. As brilliant as it is
at performing these tasks, your skin is particularly vulnerable to the harmful
effects of the sun’s UV radiation.
A certain amount of sunlight
is good for you because it helps your body create its own Vitamin D. However
too much of it can result in melanoma as UV radiation encourages the formation
of cancer-causing free radicals in your skin.
The best way to protect your skin from harmful radiation is by applying a
healthy dose of sunscreen. However, recent studies have shown that the ingredients
in store-bought sunscreens could be more harmful than the UV rays that they are
designed to repel.
Health-conscious people are
now opting to use to homemade sunscreens instead. These natural sunscreens
cause no damage to your skin, but how do they compare with the
industry-standard chemical and mineral sunscreens?
Chemical
Sunscreens
Chemical sunscreens, by
definition, use lab-created synthetic compounds to protect your skin from the
sun’s UV radiation. The compounds in chemical sunscreens absorb the rays,
prevent them from reaching your skin and disperse the rays off your skin as
heat.
Most chemical sunscreens have
high SPF values however they do not count for much because they only block UVB
radiation. They don’t do much for UVA radiation which is more deadly. Besides
the fact that they do nothing for UVA radiation, chemical sunscreens are best
avoided because they have high concentrations of toxic chemicals. Oxybenzone,
for example, has an 8 out of 10 rating for toxicity from the Environmental
Working Group.
Mineral
Sunscreens
Mineral sunscreen, on the
other hand, uses simple mineral oxides such as titanium oxide and zinc oxide to
reflect the sun’s harmful rays. The minerals in these sunscreens work on both
UVA and UVB radiation, and they don’t break down in sunlight which enables them
to keep you protected for longer. Another key benefit of using such sunscreen
is that they do not seep into your skin.
The main problem with mineral
sunscreen is they tend not rub into the skin very well, leaving a greasy white
film on the surface. Manufacturers have responded by grinding the oxide
particles ever finer, but the more they do this the more the particles are
absorbed into the skin rather than sitting on top of the skin as a protective
layer. While absorption of mineral sunscreens is better than chemical
sunscreens, it is still not desirable.
That leaves the consumer with
a hard choice to make. Will they take the risk that comes with spreading
harmful and inorganic compounds on their skin or take the risk of going out in
the sun without sunscreen? Luckily there is a third option; natural sunscreens.
Natural Sunscreens
People who use natural
products are wise to the marketing gimmicks of large companies. They know that
they are much better off not using those products however they still want the
benefits that such products give without the cancer-causing side effects. Nature
has everything that you need to take care of your skin; you just have to know
which naturally occurring compounds are best to use and how they are applied.
1 Raspberry
Seed Oil.
With and SPF value of up to 60 for UVB wavelengths and 7.5 for UVA, raspberry
seed oil is on the best sunscreens that nature can provide and you absolutely
must use raspberry seed oil in any homemade recipes that you have for
sunscreen.
2. Coconut
Oil
Coconut oil is one of those
miraculous oils that seems to be good for everything. It has antiviral
properties, plenty of medium-chain fatty acids and it tastes amazing in your
food. Now you can make use of its sun-blocking capabilities as well simply by
including it in your regular diet or using it as a base for your homemade
sunscreen. With an SPF it is not particularly good at blocking UV rays however
it works well in conjunction with other sun blocking products.
3.
Rice Bran Oil
The active compound in rice
bran oil is gamma oryzanol which has an SPF of 1.7. This makes it very poor at
reflecting UV rays however the compound is very effective at stopping the
oxidation that results from excessive exposure to the sun. Rice bran itself has
a whole host of other nutritional compounds that are good for your skin and
overall health however they are lost when the oil is refined. The final mix of
rice bran oil contains about 1% gamma oryzanol.
4.
Jojoba Oil
With an SPF of 6 for UVB, jojoba
does an average job of stopping UV rays from entering your skin, however, it
does keep your skin moist by retaining moisture and also has anti-inflammatory
properties to minimize the damage done by UV rays. Jojoba oil works as a
non-permeating sunscreen which means that while most sunscreens seep into your
skin, jojoba oil-based sunscreens stay on the upper layer of your skin which
keeps your skin safe from both UV rays and any harmful chemicals in the
ingredients list.
5.
Wheat Germ Oil
Studies showed that wheat germ oil has a relatively strong SPF of 22 UVB. Wheat
germ is also rich in tocopherols which play an active role in protecting your
skin from long-term damage.
6.
Carrot Seed Oil
High levels of Vitamin A in carrots makes
it a great additive to any homemade skin care products. It is a powerful
antiseptic, antifungal and antioxidant with an SPF of 22 which also has a
pleasant smell. Carrot oil’s pleasant smell makes it one the few sweet-smelling
oils that are not photosensitive. You can use on its own however studies have
shown that it is best used in a cream to maximize on both its photoprotective
nature and antioxidant properties.
7. Avocado Oil
The high proportion of
mono-unsaturated fats makes avocado oil form a powerful protective layer over
your skin that keeps you from tanning. The only problem with avocado oil is
that there have been cases of allergic reactions. It has an SPF of 15.
8. Olive Oil
Olive oil is best known for being heart healthy however an SPF of 8 makes it
worth considering as sunscreen, however, it is the work it does to prevent
oxidation which makes it great for your skin. The studies to identify its
protective effects were run on hairless mice. In this study, two sets of mice
were exposed to high levels of UVB radiation. The mice that had virgin olive
oil applied to their skin had a much smaller growth of tumors however the
differences between the number of tumors in each group was the same when
exposed to higher levels of radiation. The study also showed that olive applied
after the radiation has a significant effect on slowing down the growth of
tumors.
9. Almond
Oil
Almond oil is very weak at
reflecting UV rays thanks to its SPF of 5. However, it is rich in Vitamin E
which makes your skin soft and moist. Almond oil is believed to have a host of
other benefits for the human body such as boosting the immune system and
helping with irritable bowels however there is little scientific evidence to
support these claims. Preliminary results from long-term studies look promising
though.
10.
Macadamia Nut Oil
Most oils are better at
keeping your skin healthy by feeding it nutrients rather than reflecting
ultra-violent rays and macadamia nut oil is no different. It contains a rich
store of minerals such as phosphorus and a compound called cinnamic acid which
gives it an SPF of 6. Cosmetic companies are taking advantage of these properties
by adding macadamia nut oil to their sunscreen mixes. You can add it to your
sunscreen mix and enjoy all of its benefits minus the harmful chemicals in most
over-the-counter sunscreens.
11.
Soybean Oil
A favorite among Chinese
cooks, it can also be applied directly to your skin as an effective moisturizer
and sunblock. Diferuloyl glycerol is the active compound in soybean oil that
makes it so effective. This compound is found in many sources throughout the
plant kingdom however soybean stands out as one of the best sources.
Lab-extracted di feruloyl is more effective at blocking UV rays within the
270-370 nanometer range than most commercial products.
12.
Lavender Oil
Best known for the calm and
relaxing state that the smell of lavender invokes, lavender
oil‘s SPF of 5.6 makes it a great ingredient for sunscreens however
it cannot be applied directly to your skin. It makes a great additive to your
homemade mix. However, its UV blocking properties do not last long because UV
light causes it to degrade.
13. Aloe Vera
Aloe Vera is one of the most
commonly used plants in skin care. It has plenty of ingredients that your skin
loves and SPF of 20 which makes it one of the most powerful naturally occurring
sunscreens. Aloe Vera is great as a preventative measure however it does little
to repair DNA damaged by radiation. Use it before stepping out into the sun in
order to enjoy its benefits.
14. Tomatoes
This fruit has a low SPF.
However, it is worth including in your diet for that little bit of added
protection. Tomatoes more than makeup for their weak UV-blocking properties by
providing beta-carotene and lycopene which work well to heal skin lesions and prevent
skin cancer. Juicing tomatoes and spreading on the affected area won’t help so
you’ll need to include a portion of tomatoes in your diet to maximize the
benefits. The beneficial compounds in tomatoes are so potent that you don’t
need to eat large quantities to enjoy their effects. Just remember that
lycopene won’t prevent sunburns so take your tomatoes for internal healing and
apply topical sunscreen as well.
15. Green Tea
Taking two cups of green tea
every day helps your body prevent sun damage from the inside out by absorbing
UV light. Studies have shown that topical applications as well as ingesting
green tea are both effective at blocking UVB-induced infiltration from leukocytes
which are highly oxidative free radicals.
The major compound in green
tea responsible for this effect is epigallocatechin-3-gallate (EGCG). In a
study conducted on humans, the subjects were irradiated with UVB radiation, and
the resulting keratomes were analyzed 48 hours later. The study found that
applying EGCG to skin before the radiation significantly reduced the
infiltration of leukocytes.
16. Watermelon
With an SPF of 10, watermelon
can protect you from both UVB and UVA radiation. It is a carotenoid which is a
powerful antioxidant that gives carrots and bell peppers their orange-yellow
color. Beta-carotene sometimes goes as the ‘sunscreen’ nutrient and watermelon
has plenty of it.
17. Turmeric
Turmeric is one those plants
that seem to be good for just about anything. It is a fantastic
anti-carcinogenic therefore its constituent compounds are brilliant at
preventing melanoma caused by sun-damaged skin. Curcumin in the turmeric is the
compound that gives turmeric these benefits. Other plants have curcumin as well
however turmeric has it in very high doses. You can enjoy the benefits of
turmeric either by consuming it or mixing its ground powder in with your own
special mix. Keep in mind that turmeric will not block UV rays from damaging
your skin. What it does is prevent the free radicals from causing DNA damage.
18.
Shea Butter
You’ve probably already heard
about how great Shea butter is for your skin but did you know that it is also a
mild sunblock with an SPF of about 5.
19. Honey
Honey is not particularly good at reflecting UV rays however its
skin-rejuvenating properties will heal any sun damage and protect your cells
from further damage.
20.
Lemongrass
A favorite among cosmetic
manufacturers, the vitamin C and E in lemongrass make it effective at blocking
both UVA and UVB radiation. The vitamin E does most of the work however the
added protection given by vitamin C is also welcome.
Phototoxic and Photosensitive Compounds in Natural Sunscreens
You can use a variety of oils
in your homemade sunscreen recipe however you must be wary of how they might
react with your skin. Some of them smell nice which makes you want to add them
however you should keep in mind that they may be best left out.
Phototoxic compounds are oils
that make your skin even more sensitive to UV light. These are the oils that
are perfectly safe to apply while you are out of the sun however as soon as you
step into sunlight with them lathered on they cause blisters and sun-burns. If
your homemade mix contains these compounds then you would be wiser to wait for
at least 12 hours before stepping out into the sun.
These compounds include:
– Lemon juice,
– Grapefruit,
– Bergamot and others.
As you can see, these are
compounds that have high levels of Vitamin C which do not like to be left in
the sun. Use them indoors to heal and sunburns and rejuvenate your skin but
clean them off before going outside.
Dos and
Don’ts of Natural Sunscreen
Natural sunscreens do not
have as much information on real-world applications, however, using them is
still based on the same principles that govern chemical and mineral sunscreens.
Aside from knowing when to use photosensitive and phototoxic sunscreens, here
are few other tips to keeping yourself safe under the sun.
1. Don’t waste your time any
product with an SPF higher than thirty. An SPF of thirty blocks 97% of UV rays
while SPF of fifty blocks 99%. This is a small difference that is not worth the
extra cost.
2. Do apply sunscreen half an
hour before going outside. This gives it time to settle on your skin
3. Do not trust your
sunscreen to be waterproof. Most sunscreens that claim to be waterproof are
only partially waterproof at best. Even sweat can be detrimental to your
sunscreen staying on.
4. Do apply sunscreen every 3
hours because it wears off and needs to be reapplied.
5. When using a natural
sunscreen, be aware the natural ingredients vary in their SPF value. Always be
conservative when estimating how much protection is offered
