You don’t want to get burned by the sun this Memorial Day weekend
But what you put on your skin gets absorbed in your body
So, the sunscreen you choose is important
Many sunscreens contain toxic chemicals that affect your hormones & health
I’ll discuss those toxins
THREAD
We have a big holiday weekend this weekend in America- Memorial Day
The weather is starting to warm up.
And chances are you will be out in the sun.
Sunlight has so many health benefits:
•Vitamin D production
•Stimulus for Melatonin Production (better sleep)
•Release of Serotonin In Your Brain (mood boosting)
•And so much more!
But too much of a good thing can cause issues.
Which brings me back to not wanting to get burnt during the summertime.
Many people resort to using sunscreens, just like my family does.
However, I learned that many of them are filled with toxic chemicals.
These chemicals then get absorbed by your skin, into your bloodstream, where your body has to try and detox them.
This can cause unwanted health issues over time if your body has trouble detoxing.
If you have an MTHFR gene mutation you already have a disadvantage with detoxing.
So, when it comes to sunscreens and other lotions or creams you put on your body, you’ll want to make sure you are getting products that are not full of toxic chemicals.
Here Are The 6 Toxic Chemicals You Want To Avoid
•Oxybenzone
•Octinoxate
•Octisalate
•Octocrylene
•Homosalate
•Avobenzone
I will cover each of them in detail below, and how they affect your hormones and health.
Even though the FDA has approved all 6 of these chemicals to be used in sunscreen, they also report in their own studies that they are systemically absorbed into the body after use.
These studies also show that the ingredients can be detected on the skin & in the blood WEEKS after they’d last been used!
These 6 Toxic Chemicals Can Cause
•Cancer
•Skin Allergies
•Hormones Disruption
•Impact Reproduction
•Decrease Testosterone
•Impact Human Development
I will now cover each of these toxic chemicals and why you want to avoid them.
At the end, I will give a link where you can read more and dig into the research yourself.
1.Oxybenzone
Out of the 6 chemicals, this is probably arguably the one with the most issues.
It’s readily absorbed through the skin.
In research oxybenzone has been linked with:
•Allergic skin reactions
•Causes lower testosterone in adolescent boys
•As an endocrine disruptor, it increases the risk of breast cancer & endometriosis
•Caused thyroid tumors in rats
2.Octinoxate
It is also readily absorbed into the skin and has caused allergic reactions.
In a 2020 FDA study, it was found in blood samples at 16X above the FDA safety threshold.
Octinoxate has hormone effects on:
•Thyroid
•Androgen Signaling
•Progesterone Signaling
3.Octisalate
Causes allergic reactions.
It’s also highly absorbable into the skin.
Has been found at 10X the rate of the FDA’s systemic exposure level, in blood samples.
4.Octocrylene
Absorbs into the skin at 14X the FDA’s toxic systemic exposure.
Is known to kill aquatic life and coral, which some states ban the sale of it in sunscreen products.
5.Homosalate
Penetrates the skin & disrupts hormones.
European Commission recommends a maximum concentration of 1.4% due to hormone disruption.
FDA allows U.S. products up to 15% concentration.
6.Avobenzone
Can cause allergic reaction due to other ingredients it is paired with to stabilize it.
Disrupts the endocrine system and can block the effects of testosterone.
It has some UVA protection, and is often used in American sunscreens.
As mentioned earlier, if you want to dig into more details and the research, you can go here where many links are provided to the research articles.

Why Are These Important To Avoid?
Practically every one of these chemicals disrupt your hormones.
Your hormones and endocrine system are involved in so many aspects of your health.
Particularly, your metabolism.
What many don’t understand is the connection with these chemicals (and others) and how they negatively affect your metabolism.
If you are trying to improve your metabolism and health, you’ll want to avoid these toxic chemicals.
What Can You Use That Is Safe & Effective?
Unfortunately, Americans have fewer choices than Europeans on their sunscreen options.
Particularly when it comes to protection from ultraviolet A (UVA) rays.
UVA rays have less energy than UVB rays.
UVB rays are what burn the skin.
UVA rays:
•Cause the skin to age
•Suppress the immune system
•Contribute to the development of skin cancer
Most U.S. sunscreens protect from sunburn effectively by blocking UVB rays (using the above-mentioned toxic chemicals).
However, most U.S. sunscreens are not as good as European sunscreens in preventing the skin damage from UVA rays.
Most U.S. sunscreens allow an average of 3X as much UVA rays to pass through the skin, as European sunscreens.
The large majority of U.S. sunscreens sold are predominantly chemical sunscreens.
Mineral sunscreen are another type of sunscreen.
These are more commonly used in European sunscreens.
Mineral sunscreens are physical blockers that deflect the rays away from the skin.
They deflect both UVB and UVA.
The main ingredients in mineral sunscreens are titanium dioxide and zinc oxide.
Both are recognized as safe by the European Commission and FDA.
They also do not penetrate the skin and get absorbed by your body.
Mineral based sunscreens are what I recommend you use.
The drawback to some brands is they go on thick, chalky and are very white (think 1980’s nose sunscreen that was in style).
I personally don’t want to wear that kind and look like a ghost walking around ;-)
This mineral sunscreen:
•Protects from UVB & UVA rays
•Is non-toxic
•Goes on clear
•Is an Environmental Working Group (EWG) Verified Product
EWG is a great resource to learn more on the research and they have lists of approved & verified products.
This Is EWG’s List of 232 Best Recreational Sunscreens. ewg.org
In addition to sunscreens, I would also suggest using other sun-protective measures:
•Hats
•Seeking Shade
•Umbrellas/Canopies
•Sun Shirts (fishing/swim shirts)
•Staying out of peak sun times
•Sunglasses
Specifically on sunglasses, you want to make sure they are both UVB & UVA protectant.
With all sunglasses, your pupils will dilate. If there is not UVB and UVA protection, your eyes are more susceptible to damage from the rays because more are getting in with the dilated pupils.
Your One Actionable Step For This Summer
Stop using sunscreens on yourself & kids that are laden with toxic chemicals
Switch to mineral based sunscreens that block UVB & UVA rays
Check out the above links for quality products
Use other sun-protective measures
Don’t get burnt
