Too much sun is dangerous. During activities in the open air, it is necessary to seek shadowy areas and to avoid exposure during the hours of maximum sunshine which are between 11:00 am and 4:00 pm. It is preferable to wear a hat and sunglasses and to choose a sun screen with an index of protection adapted to the particular sensitivity of your skin and the intensity of the sun.
Apply your products liberally before exposure and especially after swimming and re-use every other hour. The protection index posted on sun screens is guaranteed only by observing these conditions.
Recently we have heard all kinds of rumours and opinions concerning the very high indices of protection: does a higher SPF really offer a better protection or not? Does a “total screen” really exist or not? Why are protections superior to 50 (??) prohibited? As consumers, we do not know any more what and whom to believe…
Here are the results that we have obtained after a thorough research.
All that exceeds index 20 does not make a great difference from the point of view of protection. Protection against UVB-rays ensured by an index 15 is 93,3%, that of an index 20 is 96%, that of index 30 is 97,4% and that of index 40 is 97,5%.
If one classifies the filters according to their effect, one notes that above index 15 the difference between the 6 other indices (20, 25, 30, 40, 50 to 50+) corresponds only to a relatively weak margin of 6,7%. That means on average 1% of progression by index knowing that the difference between index 40 and index 50 is even tinier, 0, X % per higher factor. 
Skin Deep notices the same phenomenon.
“The high indices of protection offer only small increases in the real world of the SPF. But, this small change makes it possible for the bathers to remain longer in the sun – thereby absorbing thus more total radiation – before a sun stroke sends them inside. In this process, appreciably higher quantities of chemicals present in the products of solar protection of a higher SPF can penetrate the skin and involve a much higher internal exposure with potentially dangerous components. The user thus finds him/herself with a sun stroke and a “toxic body burden” significantly higher due to the chemical ingredients used for the manufacture of the protective sun screens with a high index. ” 
With regard to safe sun screens available in Quebec (like everywhere else in the world besides), I say it while leaving: the choice is very restricted and products are far from perfect!
Here are the best options:

True Natural SPF 50 listed 1 on Skin Deep purchased via USA and expected as the Christian Salvation, is as white as other mineral-based sunscreens … the “Sun stick face & body” SPF 30, 0.5 oz (like a lipstick tube) is more yellow and not at all greasy, but really, not buyable! Both pieces 65 $ ! I do not know about you, but for myself, I would do the “face & body” max two times with this amount of product…
Ah! I do not know anymore … should I lose weight or stay in the shade all summer long?
Following the many emails coming from Netsurfers eager to contribute to the enrichment of our community and the changes in our consumption patterns, I added several sunscreens having a cleen INCI List and available over here.
Green Beaver SPF 30 certified ECOCERT, 15.99 $, ECO logical skin care SPF 30, 15.99 $, graded 1 on Skin Deep, Heiko (see chapter for children), and Keenu SPF 30 certified ECOCERT (without nanoparticles) are availeble in natural products stores.
All these physical sun screens are secure and I all tested them except for Keenu: if they are perfectly advisable for the holidays in the sun, I think that the challenge is still present because I did not find a product yet that, in terms of safety, texture, appearance and price, enables us to use it on a daily basis, before using make-up…
Active ingredients: Zinc oxide 19%.
INCI: Aloe barbadensis (certified organic aloe vera gel), Purified Water (aqua), Capric/caprylic triglycerides (derived from coconut oil), Glycerin (vegetable), Hyaluronic acid (vegan source), Glyceryl stearate SE (derived from vegetable oil), Stearic acid, Lecithin phospholipid, Tocopherol (vitamin E), Allantoin, Vitis vinifera (grape) seed extract.
No nano technology (average particle size is 240 nm)*.
I have not tried it, here are Adria’s comments:
“Effectiveness: Cream of the crop for lightness and smoothness of texture, but not very water-resistant so not great for heavy sweating.

|There is also a Lavera Sun Spray SPF 30 Neutral (older formulation) but rated 4 on Skin Deep, if I understood well, because of the technology used (nanoparticles).|
At the pharmacy
|La Roche-Posay ANTHÉLIOS SPF 40 (attention, no other sun lotions of La Roche-Posay which may be graded as high as up to 7 !) is graded 2 on Skin Deep which is frankly a good score in terms of harmlessness for a sun lotion and it offers a very good protection. It contains 12 ingredients including 2 parabens and triethanolamine (interacts with nitrites to form a carcinogenic nitrosamine, graded 6 on Skin Deep) but one could make use of it only for the face during very sunny days or on holiday. It use to be available in pharmacies almost everywhere in Quebec.Analysis of Skin Deep: excellent UVB (SPF) protection, excellent UVA protection, good UVA/UVB ratio, stability of the product, excellent. Better protection than Badger but a little more toxic. It is my choice for holidays in the south, in the sun. Beautiful texture, is spread out well, the white filter is less obvious (just titanium dioxane 5%) than the other solar protections retained by the Guide. If we have eliminated all the other toxic hormonal disturbers and ingredients in our products of care, we could make use of them on occasion… because what counts most, is to avoid the“cocktail” effect of cosmetics.If the adviser at the pharmacy ensures you in an irritated tone that this product with index 40 does not exist because it has been so many years that she works there and that the pharmacy has never sold it, say to her calmly that the product exists and suggest that the manager should order it in the place of the other indices which are more toxic. We have come to a point where people must become aware of the importance of using healthier products and it is always necessary to keep in mind the power one has as a citizen and as a consumer. I do not think that the pharmacies will refuse to replace their products on the shelves in so far as they are sure that they will be sold. It is up to us then, by the choices that we make, to require changes towards more safety and more social and ecological engagement from them.Update : It seems that this sun lotion is not available in pharmacies in Quebec. A Net surfer wrote even to the head office of Jean Coutu which confirmed that one does not retail it in these pharmacies. Remains thus the purchase on line.|

Very few changes in the new formula and in spite of the long list of “withouts” and of the anti-age virtues, hydrating and so on, the list of ingredients reads as follows: if the basic ingredients are well graded between 0 and 3, the ingredients that are “ naturally present in the essential oils” should be well taken into consideration before choosing the product: 2 hormonal disturbers and eugenol graded 7 . Indeed, in my view, this sun lotion is not more safe than the La Roche-Posay cream which is a conventional cosmetic without certification…Benzyl Benzoate (5 allergenic, benzoate benzyl has shown estrogenic activity increasing the proliferation of breast cancer cells in vitro, women with breast cancer, please abstain!), Benzyl Salicylate (6, associated with hormonal disturbers), Eugenol (7, allergenic, irritating, immuno-toxic, neuro-toxic), Farnesol, Geraniol (6, allergenic irritant, immuno-toxic), Limonene (6 irritant, allergenic, eco-toxic), Linalol (5).
The ingredients resulting from essential oils that are more problematic (benzyl benzoate, benzyl salicylate, eugenol, farnesol, geraniol, limonene, linalool) are the same as for the PHYT’S SOLAIRE fluide protecteur haute protection SPF 50 .

|Desert Essence Age Reversal SPF 30 Mineral Sunscreen , very well rated (2) on Skin Deep.The products of this brand are quite popular in Quebec. You have a good chance to find it or to order it in the boutiques of natural products. The remarks of the consumers are however the same ones as for all the other sun screens containing minerals: too much white, that is seen! Here are the ingredients:|
|Zinc Oxide 5 , Titanium Dioxide 2 , Phenoxyethanol 4 , Santalum Album Oil 2 , Tocopherol 1 , Cyclomethicone 2 , Camellia Sinensis Leaf Extract 2 , Citrus Aurantium Bergamia Fruit Oil 2 , Caprylic Triglyceride Citrus Aurantium Bergamia Fruit Oil 1 , Cetearyl Alcohol 1 , Glyceryl Monostearate 1 , Ubiquinone 1 , Aloe Barbadensis Leaf Extract 1 , Vitis Vinifera Seed 0 , Vegetable Glycerin 0 , Punica Granatum Extract 0 , Cucumis Sativus Fruit Extract 0 , Sodium Ascorbyl Phosphate 0 , Caprylyl Glycol 0 .|
The same rule as for the other products of the Guide of non-toxic hygiene, beauty and cosmetic products applies for sun lotions: it concerns only the products which have these grades and which are advisable and not all sun lotions manufactured by these companies.
You will find the precise description of all the ingredients according to the list of Rita Stiens available on her site as well as some sun lotions which she recommends: Melvita, Pro Sun Natura sun lotion SPF 25, impeccable composition. You can see its card in her book La vérité sur les produits cosmétiques naturels (The truth about natural cosmetic products), Lavera for children about which I wrote above, sun lotion Weleda with Edelweiss, SPF 20 and Phyt’s which we also described.
|Miessence Reflect Outdoor Balm, SPF 15 is rated 2 on Skin Deep.According to Skin Deep: excellent UVB (SPF) protection, excellent UVA protection, excellent UVA/UVB ratio, stability of the product, excellent. Oxidized zinc 29.5% and only seven other ingredients graded between 0 and 4 which is very good from a harmlessness point of view. In theory, this product seems very good, presents an excellent protection and a list of clean ingredients, but I did not test it and I can say nothing about its texture.|
I saw on Skin Deep that there is a stick (practical for the hand bag) of mineral powder (zinc, titanium, graded 1) Trukid Sunny Days Facestick Mineral Sunscreen Uva/UVB Broad Spectrum SPF 30 and more.

A Net surfer asked me why I propose on my www.corneliadum.com website a sun lotion with parabens and nitrosamins (La Roche-Posay) although I do not stop saying that parabens should be avoided!?! It is a good question whose answer is truly enthralling. It is worth reading what follows to better understand the choice that I made. Let us remind that the choice of a sun lotion does not emanate from a gesture of coquetry but rather from a need for health protection, especially for children, and that there the “effectiveness” criterion is more important than for a lipstick…for instance. In fact, if you think that with products with mineral filters one has settled the question of toxicity of sun lotions, you are mistaken! Actually, between two evils it is necessary to choose the lesser one…
If you have succeeded to find a convenient sun screen from the point of view of harmlessness, not too white and not too oily and if you have enjoyed the sun rays here then is a nourishing and restoring product to complete your joy:
|Zorah hani after sun, exclusive mixture of organic argan oil, organic chia oil, and organic kendi oil, 122 ml, 29.99 $, the organic ingredients have been verified by Quebec Vrai. Available on the Zorah Website.

Voilà, for a few years one has not stopped telling us us to avoid the synthetic filters in the sun screens because they are either allergenic (because of the octocrylene) or because they behave as estrogens which endangers the hormonal equilibrium and can cause cancer. Such is the case with the chemical solar filters Ethylhexyl Methoxycinnamate, Benzophenone-3 and 4, Oxybenzone  and Methylbenzylidene Camphor and this is why, especially if you had a hormono dependant breast cancer, I would say that it would be prudent to rather choose solar protections containing mineral filters than creams with synthetic filters. This is quite beautiful and one would obey without saying anything but actually we are not out of the woods yet…
The cosmetics industry has been proposing for a few years creams with mineral screens of which the main ones are zinc oxide and titanium dioxide which are natural and form a protective barrier for the body by reflecting the light. One however reproaches dioxide zinc for being a not very ecological ingredient for our immediate environment on the same basis besides as the sun lotions containing synthetic filters which endanger the coral reefs of the whole world. But, as important as it may be, this ecological aspect is not the major disadvantage: in the Guide of the best cosmetics 2011-2012, the real problem of mineral filters is very well explained. Actually, the danger comes from the way in which the creams are manufactured, because these minerals, to avoid the fine white layer that remains on the skin after use and which the consumers hardly appreciate, is reduced to very fine particles, below 100 nanometers in size, which makes nanoparticles of them which, considering their capacity to penetrate very quickly in the body, given their reduced size, are considered to be very toxic and suspicious enough for our health with a large inflammatory potential. As we nkow, many diseases of the immune system such as the cancer and the fibromyalgia are related to inflammation .
Do Certified Organic Sunscreens contain nanoparticles or not?
According to this article Ecocert certifies products that contain titanium dioxide greater than 100 nm because some studies, made by several manufacturers of organic cosmetics, show that a particle diameter greater than 100 nm would not be a danger since the nanoparticles remain on the surface layer of the epidermis … This statement reminds me the one about the potassium alun whose ” molecular structure ” would be too high for it to be absorbed through the skin … but we never found traces of this study. ..
” On the other hand – says the article – some manufacturers ( Melvita, Lavera ) encapsulate the titanium dioxide in vegetable stearic acid (derived from coconut oil fatty acid), vegetable triglycerides or silica. This encapsulation stabilizes the nanoparticles, makes them nonvolatile and further reduces the probability of their penetration into the skin ” .
One thing is sure, there is still lack of studies on the absorption of titanium dioxide by the skin…You be the judge of this “without nano story”…
The sun lotions containing mineral filters and labelled as being “without nanoparticles” are rare. I saw some for the first time last year (see Badger above). The European legislation on organics did not require the mention “without nanoparticles” on the packing of organic sun lotions before 2013. In Canada, I have heard nothing of this kind of concern for consumer protection until now. I remind you that the omnipresent “hypo-allergenic” does not give any guarantee to you (see the chapter “ Reading the labels ”) and that “the total screen” and the “waterproof” sunscreen do not exist.
The Guide that I have quoted above, although harmlessness is not the first criterion in the classification of the products, affirms that on 138 products tested, only 4 are recommended!!! Which is proof that it is serious! They recommend three Dermaterm products (without nanoparticles) and an Occitaine en Provence which contains all the firm parabens and PEGs and is classified, by the Guide itself, 2/5 in terms of safety.
For the toxicity of Dermatherm (Pure Sun SPF 50+ Sun lotion very high protection, 14.40 Euros, certified Cosmétique Bio, http://www.dermatherm.com ), I will not make an analysis considering that the product is not on sale in Quebec or Canada, but, if you wish to buy it, you can buy one of them, (one should, in this precise case, in spite of certification) by checking ingredient by ingredient or with the list of Rita Stiens which you will find on the Internet, or, better still, on Skin Deep. It is not a problem that this site is in English because the lists of ingredients abide by an international nomenclatura maintained in force in Europe, in Canada, in the United States and Japan.
Few products obtain the green grade on Skin Deep too. The fourth year of the Guide solaire of the EWG gives bad marks to the current tendency of the products of solar protection, with some notable exceptions. Thus, the researchers of the EWG recommend only one small fraction of more than 500 sun screens and the sports solar screens for this season. The list of the best solar screens is available on the site of the EWG.
All this is explained by a surge of sometimes exaggerated and unfounded claims of the SPFs above 50 (which in fact increase the risk of toxicity) and of new information about the potentially dangerous ingredients, in particular those recently updated by the data concerning the link between vitamin A present in the majority of the solar screens and the accelerated growth of skin tumours skin and of lesions. The EWG has again warned against oxybenzone, (a chemical which penetrates the skin and then enters the blood stream) a known hormonal disturber present in approximately 60% of the 500 analyzed solar screens. 
If, after all that I have just told you, you desire “surer” products (as far as that is possible), you could order some via Internet on Skin Deep (several are very well graded as far as harmlessness and effectiveness are concerned, but for texture and colour it remains to be seen how one will look like after use: like a Geisha, an greasy French fry or an old lemon. Do not forget to drop me a line!
So, to answer the question that I asked two pages higher, I chose the product La Roche-Posay Anthelios because it had been recommended by a local newspaper as being less toxic (which is true considering its grade 2 on Skin Deep) although it contains parabens, because products containing mineral filters on sale in Quebec are less powerful from a protection point of view and they contain nanoparticles.
The problem is thus to choose between the toxic and disturbing chemical filters from a hormonal point of view, the nanoparticles and parabens, because, as you see, there is not yet a product of solar protection that is safe, effective and (sincerely) aesthetically suitable. Even the Dermatherm product which is not on sale over here and which is certified organic contains aluminum… In conclusion, we are still waiting for the miraculous product and please, importers, distributors, salesmen, do your share!
There are some recommended solutions for the lovers of the unconditional “glow”, but I have not seen them on our markets. Buying online is now the only solution. Lavera Sun Sensitive self tanner for face and body certified organic seems to be a product that is popular as well as the Dr. Hauschka’s Translucent Bronze Concentrate. Another U.S. company, True Natural makes very good sunscreens rated green 1 and 2 on Skin Deep (I’ve tried them and I’ve liked them) also makes a All Natural Self Tanner.
Othewise, all these tanning lotions are using ingredients extracted from sugar cane or beets to give this “healthy glow”, but the safety of the products also depends on the other ingredients in the mixture …
The conventionnel tanning products are obviously very misclassified on Skin Deep (look sor self tanners).
Some medication may increase sensitivity to sunlight, heat, or both. Consult this link to see if you need to take precautions with your medications during the summer months.
Many women have concerns about retinol (vitamin A). Is this ingredient photosensitizer or not? One can find conflicting advice…
Here is what Skin Deep says about and the number of studies seems to be “fair” ….
I am not able to resolve these disputes, I use it too, but the doctor told me clearly to avoid any sun exposure and put sunscreen every day.
So, sometimes you have to go with your intuition, do what your conscience tells you to do.
“About RETINOL (VITAMIN A): Retinol (Vitamin A) is a naturally occuring substnace essential for healthy metabolism. Excess exposure to Vitamin A could be associated with toxicity such as effects on reproduction and development. When exposed to UV light, retinol compounds break down and produce toxic free radicals that can damage DNA and cause gene mutations, a precursor to cancer. Recently available data from an FDA study indicate that retinyl palmitate, when applied to the skin in the presence of sunlight, may speed the development of skin tumors and lesions”.
Finally, it is good to know that in Canada, sun lotions are considered as medication and not as cosmetics. So, manufacturers are not bound to affix all of the ingredients of the manufacturing formula and will often affix only the active ones. You must focus on products which label the active as well as the inactive ingredients .
Products labelled by an organic certification affix all of their ingredients.
For physical screens, it is preferable to opt for those who affix “ no nano ”, without nanoparicles, but be yourself the judge of that decision.
Also look for the words ” protects against UVA and UVB ” since the FPS generally indicates protection against UVB rays only.
