Why is it that sunscreens rely on chemicals to 'protect' you against the sun but when tested for their SPF rating they only measure the amount of UVB rays deflected?
It's one of the startling questions I found myself asking after months of researching why and how chemicals are used in mainstream sunscreens. The reason I began? simple, my Mother had started to use sunscreens when they first came on the market in the 80's and within 5 years she was being treated for skin cancers. The prolonged and often aggressive treatments and surgery she had over the next 20 years proved to be a shocking experience for her, and in essence, me too. I eschewed wearing sunscreen very much at all as a kid and early adult. I got burned now and again, but generally I avoided getting very burned because I disliked the aftermath of cold-tea bag soothing sessions and looking like a cooked lobster.
Only a broad spectrum sunblock like Zinc Oxide will reflect both UVA & UVB rays. B rays burn... A rays go deep into the dermis...they're the ones responsible for long term damage. But we need the sun to make Vitamin D...which is an endemic process (occurs inside the body where it is used) 'switched on' by UVB rays. So we need sun exposure, but not overexposure. Y'get it?
Why are only two chemical sunscreens passed as 'safe' (but not GRAS 'generally regarded as safe') for cosmetic use by the EWG when there are approximately a dozen in use (and more available for use) in commercial products all over the world?
YUP, that is correct. Here's the link. Go read it, then check your labels, then take a deep breath.
'They' will put things on the shelf even though the safety of ingredients is questionable from the scientific research carried out, or, from anecdotal evidence that has yet to be verified by scientific research.
It's like saying "We're not 100% sure a fall from that height will kill you but until someone actually does it and we can, with scientific conclusiveness, agree that it results in death or injury, then we're not going to advise you not to jump. Here, by this bottle so you can have 30 minutes of fun in the sun". Doesn't that make you consider looking before you leap?
Chemical sunscreens are absorbed by the skin and in turn 'absorb and scatter' UVB rays, whereas Zinc Oxide (and *Titanium dioxide) powder reflects both UVA and UVB rays. So in effect it 'blocks' the rays whereas the chemical ones 'screen' the rays. These chemical sunscreens are absorbed by our skin, therefore our bloodstream and lymph fluids will have those chemicals floating within and around our body (scientific studies confirm the presence of oxybenzone chemicals, routinely used in sunscreens, to have been found in breastmilk). In comparison, zinc oxide stays on the surface of the skin and does its job. It's another reason why Enviro Protection Lotion is oil based, forming a barrier for protecting the skin and our bodies.
There's also an issue with the chemicals used in sunscreens having an effect on our hormones. Unfortunately, for some people the fact that they create a product that is invisible when applied makes it ok for that product to be on the market...the delusional rationalizing is just astounding. And what about the implications of slathering that stuff on your baby-toddler-child-teenager-adolescent for the next 18 years or so while their body grows and matures? The implications of our choices should be part of our decision making process because it's not just about you. Your choices can affect your children, your environment and life on the planet.
But before you go out to get a 'safe' chemical sunscreen, consider the filler ingredients used in them. Some of these are known skin allergens...for example:
"The FDA must also look closely at the so-called inactive ingredients in sunscreens. These typically make up 50 to 70 percent of a sunscreen. One ingredient in particular is a cause for concern: the preservative methylisothiazolinone, which is used alone or in mixtures with a related chemical preservative called methylchloroisothiazolinone. Lab studies indicate that methylisothiazolinone is a skin sensitizer or allergen. Over the past several years, physicians have reported serious cases of skin allergies, most notably in children exposed to methylisothiazolinone, by baby wipes and products meant to be left on the skin (Chang 2014). In a study published in 2014, researchers at Baylor University surveyed the ingredients in 152 children’s body care products labeled “hypoallergenic” and found methylisothiazolinone in 30 of them (Schlichte 2014). The American Contact Dermatitis Society named methylisothiazolinone its “allergen of the year” in 2013." EWG
MEM uses Shea Butter and botanical oils to provide the bulk of the product and also to disperse the zinc powder evenly throughout the lotion. Shea Butter is a beautiful ingredient that nourishes and protects the skin. Every ingredient is there to perform a beneficial function...there is no 'filler'.
The new smoother, silkier, more luxe version of the popular ESB from MEM. Suitable for sensitive skin and babies. 100% natural and vegan with 85%+ Certified Organic Ingredients. Small batch produced, made in Australia.
A hydrating formulation provides a light covering with an approximate UV protection of 15+. The luxurious silky matte cream is enriched with Shea Butter, Macadamia, Camellia Seed, Pomegranate Seed Oil and Lavender, which help to nourish, protect and repair. See the Ingredients section for more information.
This totally natural suncare/sunprotection lotion is developed using pure grade non-nano Zinc Powder that reflects UVA and UVB rays, at approximately 20%+ formulation to assist in preventing sunburn, nourishing and protecting the skin when outdoors in direct sunlight and exposed to the elements. Wearing an everyday sun protection lotion helps to reduce skin damage and premature ageing caused by over exposure to the sun's rays.
It's safe for bubs, kids, adults, everyone. (NB: make sure babies or pets can't lick or suck or any part of their body where the Solar Lotion has been applied. Please read the 'Caution' section for more information).
100% Botanic and Organic. Vegan. Naturally Cruelty-free.
Skin nourishing ingredients. Synthetic-free!
The ocean-friendly formula is biodegradable. (ie: it won't harm the fishies in the sea, rivers, dams or creeks). It's botanical wax component means it is a vegan, naturally cruelty-free, and waterproof, however, re-apply if you've wiped your face with a towel after swimming. Use on the face, neck, decolletage, forearms and the back of the hands when driving for long periods of time.
Please note that MEM's Solar Lotion or Balm is not SPF rated. I trial my products on willing humans with the outcome of a 25mins+ no-burn time. However, the BEST sun protection is thick-weave clothing and a hat. Never rely upon any lotion or cream to protect you for more than 25mins in direct sunlight.
NB: The tint is a generic shade to take the white-cast off the product. You can wear it underneath mineral make up suited to your complexion for everyday protection. As it is not a foundation but a lightly tinted day cream I recommend purchasing a sample to see how this looks and feels on your skin.
It's available to purchase as a big 50ml pump size and trial/purse size too.
Because of the coverage given, I only use about 2 pumps of lotion for my face and neck. Then another 2 for my forearms and back of my hands. I moisturise before applying it so that my skin is soft and ready for the sun protection lotion.
The new cold homogenisation process I'm using when formulating the Zinc powder into the blend ensures a great dispersal of the non-nano Zinc powder. Clumping or 'white-fleck' is reduced considerably so that the protection given a uniform coating rather than having to rub and spread the zinc over the skin. That bugged me heaps ;) and I'm relieved to have devised a process that provides a smooth, even coverage.
Generally I cover up everywhere else if I'm going to have prolonged sun exposure. A long sleeve rashy vest for swimming/body-surfing, a thick shirt if gardening or walking etc. Enjoy your time in the sun and limit direct exposure for long periods of time. Cover up when spending lots of time outdoors and look after your skin. It's the one thing you'll wear your whole life, so it's worth the effort to look after it well.
* I've got reservations about using Titanium dioxide in my products because...(read link information) and you should too if you're using a spray on sunblock with Titanium dioxide because you've read it's 'one of the safe one's'... it is, but size does matter, and so does the way it's used...read the link to establish why.
The risks associated with using nano particle sized powders is real. Therefore MEM does not use them in any products.
