Hi Mia,
It is difficult to believe that this sunscreen has SPF 30. I would have estimated SPF 15 (at the most)!
There is another thing that I would like to correct in the INCI list. Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is stated as film former. It is a thickener (from Seppic).
I think it can provide decent protection when you don't stay much outside.
(In the summer (May to October) I would go for a higher SPF and PPD sunscreen though in Florida).
Good luck with the sunscreen!

Thanks Eva V., so glad I asked!

Would this from Neutrogena do? Ultra Sheer liquid spf 70:

Avobenzone 3%, Homosalate 10%, Octisalate 5%, Octocrylene 7.5%, Oxybenzone 5%.
Water, cetyl dimethicone, silica, styrene/acrylates copolymer, C12-15 alkyl benzoate, ethylhexylglycerin, steareth-100, caprylyl glycol, pentylene glycol, steareth-2, cyclopentasiloxane, polyester-7, chlorphenesin, bisabolol, disodium EDTA, acrylates/dimethicone copolymer, butylene glycol, BHT, mannan, xanthan gum, polymethyl methacrylate, camellia oleifera leaf extract, diethylhexyl 2,6-naphthalate, tocopheryl acetate, portulaca oleracea extract, pantothenic acide, retinyl palmitate, ascorbic acid, phenoxyethanol, fragrance.

TIA, Mia

I think that when you live in a climate, like Florida, with a lot of unintended sun exposure, a physical blocker would be better. A sunscreen that has high amount of ZnO, or Tinosorb S and M, or Mexoryl filters.
Basically, either a well formulated US (or Japanese) sunscreen (with ZnO) or a well formulated sunscreen from the EU. (The new Anthelios SPF 50+ Melt-in Creme (EU) does not contain OCR. It is based on Tinosorb S, Mexoryl S and XL, AVO, TiO2, EHS (Octisalate). The fluid version contains all these filters and OCR. They now use an SPF/PPD booster, so the amount of organic filters are dramatically reduced, yet achieve high SPF and higher PPD-ratings than the previous formulations. It also results in a lighter and more pleasant product.)

Hi Eva:)

I am using the following sunscreen at least 45 minutes before I go outside the house:
vanicream sunscreen sensitive skin spf 60

However, I have still gotten more wrinkles in my forehead. I am only using sunscreen when I am outdoors, when I'm indoors then I am not using it. Could one get wrinkles when beeing indoors too?

Thanks

Hi there,

I don't know this sunscreen, but what is important whether it has good good UVA protection.
Windows filter UVB rays but let the aging UVA rays through.
Wrinkles are also influenced by genetics and your behaviour in the sun in earlier life.

To recommend a sunscreen available in the US is not that easy I have to admit. I do not know all the products available. But the few I know and I personally like would be MDFormulation Total Protector SPF 30 (7.9% ZnO, 7.5% OMC, 4% OS). It might not be the greatest of them all but it is an extremely light sunscreen with a very natural finish. No whitening. Fragrance free. Could contain more anti-oxidants though. (It's about $ 22 for 75 ml). Packaging: tube. It is definitely non-greasy but somewhat waterproof.
The other one I really like is MAC Studio Moisture SPF 15 (6.9% ZnO, 3.5% OMC). Fantastic consistency, very good anti-oxidants. The only drawback is that it is lightly fragranced. (It's about $ 30 for 50 ml). Packaging: pump. It is definitely non-greasy nor waterproof.
The third one is actually Clinique Even Better Hand Creme SPF 15 (3% AVO, 5% HS, 5% OS). It is marketed for the hands but it does contain some very good anti-oxidants in a white fragrance-free emulsion that is hydrating enough for normal skin and has a very natural finish on the face (it is far too light as a hand creme though!). (It's about $ 35 for 75 ml). Packaging: tube. It is definitely non-greasy nor waterproof.

Eva recommends a few other S/s w/in that thread. I just bought the Obagi nu-derm medical sun-shield spf 50 & have worn it twice. Quite matte and not at all whitening - I'm quite encouraged at this time!

Thank you Mia for posting the thread. These sunscreens were recommended as non-whitening, non-greasy, affordable and available in the US. There are far better sunscreens than these out there. But it always depends on what is the purpose of the sunscreen. Daytime, outdoors activity etc.

Dear Eva,

I've been looking around for a sunscreen that's:
a Affordable
and
b offers protection from UVA1/2 and B.

After reading some of your posts, it seems that Mexoryl SX/XL are pretty decent UVA filters, so I've been using Garnier's Ambre Solaire, with the following ingredients;

But does this offer sufficient UVB protection?

Hi Eva,

I too am eagerly awaiting the availability of your product :-) In the meantime, I'm on a desperate search for an 'invisible' sunscreen. I'm realistic - it doesn't need to actually be invisible, but as a male I feel self-conscious when wearing anything obvious.

I'm currently in Paris and was excited to use some of these touted EU sunscreens but all have been super whitening. I have pale skin (blonde redhead) but the ones I have tried made me look sickly:

- Bioderma photoderm akn mat white spf 30
- La Roche-Posay anthelios ac matte extreme fluid spf 30

They were both, however, cosmetically acceptable (matteness, evenness, etc.) bar the white cast. I've also tried Avene hydrance optimale uv light, which was actually invisible, but really a moisturizer and not at a sunscreen at spf 20.

Whilst I'd like to have something with Tinosorb, etc., at this point in time I really need something close to invisible, even if the protection is not quite as good as I'm afraid I will end up wearing nothing at all. I would, however, prefer to avoid nano-particles (are these even common in the EU?).

I'm thinking of giving Avene Cleanance Solaire SPF 40 a shot - but I'm not sure it will be any different from the one's I've used thus far.


I'd love to hear your thoughts.

Thanks,
Tom.

[phased]

okay, i went ahead and tried the Avene Cleanance Solaire today and as suspected (i'd read a couple of anecdotal reports) it's much less white. in fact, i'd say the whiteness is bordering on tolerable.

downsides? a little sticky, a little shiny, but i think i can deal with that. it's actually spf 30, not 40 though - does anyone know the PPD? and can anyone confirm it's photostability? i think i saw the scientific names for Tinosorb, but would love confirmation.

finally, are the other avene EU sunscreens as cosmetically elegant as this? of the two i've tried (the SPF20 moisturizer), they certainly seem to be the better of the bunch. i'd love to hear any further recommendations.

All products that claim to have any SPF have to document that they comply. They have to have tests that confirm the SPF value stated on the package. Usually products from L'Oreal group have much higher SPF than on the products (so they can claim min. UVA protection of 1/3).

Hi Tom,
I understand your problem very well.
First, let me discourage you from spending money on Avene Cleanance SPF 40 sunscreen. It is extremely oily (even though made for oily/acne-prone skin). It is not white at all but very shiny on the skin. The UVA protection is not as great either.

Nano-particles in the EU are common. Esp. nano TiO2 in sunscreens (but nano-vitamin E etc. in other products as well).

I also agree with you on using a lower SPF (every day) is better than not using any at all.

There are several solutions.
One is the LRP Anthelios sunscreen SPF 15 sold in the US. It contains Mexoryl XS and provides good UVA protection without any whiteness.
Other solution can be MD Formulation Total Protector SPF 30 with ZnO or Mac Studio Moisture Lotion SPF 15 with ZnO. I wrote before about the Even better hand creme SPF 15 from Clinique how nice the consistency was as a face creme (and far too thin and matte as a hand creme). Both the Mac and the Clinique are available in the US, very affordable and have an elegant invisible finish on the skin. Both provide UVA 5. Most likely they even have samples to try out before purchase so you can actually wear it on your face before you decide you like it.

One of the members of this forum was very kind and sent me a Japanese sunscreen: Allie: Moisture Gel SPF 50+ PPD +++ (2012 version). It is the lightest gel-creme sunscreen I have ever seen! It contains close to 10% ZnO and 2.56% Uvinul A along with 7.49% OMC. Apparently, it is the most popular sunscreen in Asia at the moment , and I can understand why.
It feels more like a normal moisturizer (very light) not at all like a sunscreen. The finish is also like a light moisturizer, no oil, whiteness and all that associated with sunscreen, just an elegant smooth finish. Your skin actually looks like it is lightly moisturized, clear and glowing (with health, not with oil! ) I believe it fits best for hot/humid climate or/and for people with oilier skin.
If you can get hold of this sunscreen (on the Internet) it maybe a good investment.

Hope I could be of any help.
Let me know which sunscreen you eventually end up with!

I saw your post after I replied to your other post.
The Cleanance sunscreen is the old formulation of Avene (without AVO) and has OMC, Tinosorb S, Tinosorb M, TiO2 and some ZnO. It is a photostable sunscreen, but as I remember from the study of the measurements Ciba did on some sunscreens, Avene's sunscreens did not end up very well on UVA protection that time. This might also be the reason for that Avene has reformulated their sun care range and include AVO and replaced OMC with OCR. The new sunscreens are very drying in my opinion and extremely whitening (even for me). they feel as if the Tinosorb M filter would not been properly incorporated into the products and streak on and peel-off from the skin.

[phased]

hey eva,

thanks for such a thorough response. i've actually been wearing the avene cleanance for a few days now and it is probably more white than i first realised and the oiliness is really getting to me - particularly with these warmer days. hardly the solution i was looking for.

thanks for the recommendations - the allie option sounds interesting. i'm actually based out of the EU for the next 6 months so would really like to find something here if possible - at least in the interim. (i'm originally from australia, not the US.) i'd always been told the EU sunscreen selection was far superior to anywhere else so i'm a little disappointed by what i've found so far.

are there any readily available facial sunscreens in the EU (i'm currently in france) that might fit the bill? as aforementioned, i'm mainly after matteness and no-whiteness.

just thinking out loud here - i've never had much luck with tinosorb or zinc proudcts - is mexoryl worth looking into? can this be bought in the EU?

(i'd also been keen to hear of any body sunscreens you might recommend OTC in EU. again, matte and invisible.)

many thanks, eva - you've been much help thus far!

[phased]

oh and i should probably reiterate my aversion to nano-particles. i do this out of precaution.

I see. If you are in the EU then there are plenty of good sunscreens to choose from (when it comes to UVA protection). To be honest I have not found one sunscreen that I find fantastically pleasing cosmetically and has either Tinosorb filters or Mexoryl). Mexoryl filters you will find in L'Oreal group's products (Vichy, LRP, L'Oreal Paris, Garnier, Helena Rubinstein, Biotherm, Lancôme etc). It is patented to the L'Oreal Group.
What might be worth having a look at is Eucerin's line of sunscreens for the body (OCR, AVO, Tinosorb S, TiO2) and their fluid sunscreen SPF 30 or SPF 50+. Both are supposed to be very light and mattifying and include these filters: OCR, AVO, Tinosorb S, TiO2.
http://www.eucerin.c...tion-solaire/1/

One thought about nano-particles. In the EU it is mandatory from Jan 1. next year to let consumers know whether a product contains nano-materials by writing it on the INCI list.

[phased]

Thanks again, Eva.

I tried SkinCeuticals (another L'Oreal group product, I believe) Ultra Facial Defense SPF50 which contains Mexoryl filters (and perhaps Tinosorb, too), and whilst I wasn't able to give it the sweat test, it looked very acceptable in terms of finish and whiteness. However, it also contains titanium dioxide (i'm not sure what %), but I'm guessing this is nano-sized. I say this because it appears L'Oreal appears to utilize nano-technology and the non-whiteness makes me assume as much. Can anyone confirm? Are there an Mexoryl based products that you know of that either contain non-nano TiO2 or ZnO or without these ingredients at all?

[Eva Victoria]

L'Oreal patented formula does contain TiO2 along with Mexoryl SX and XL, AVO and Tinosorb S. They only use ZnO in some of their Skinceuticals sunscreen formulations for the US market (and some others for the Asian market). In the EU they do not use ZnO. The Tio2 is nano-sized and has compatibility with AVO (the only exception is when they use TiO2 in make-up formulation, then they use the full size TiO2 as many other companies do as well).

[jep]

Eva,

I can't say for other EU countries, but I am absolutely certain (have used the products) that Skinceuticals DO use zinc oxide in their formulas sold in the UK. The formulas in the UK are identical to those sold in the US.

[Ali]

Sorry your wrong there, the UK version of skinceuticals sunscrees no not use Zinc oxide, thats not to say you cant purchase the US version from places like eBay.

Ali, I'm not wrong. I have purchased 2 SkinCeuticals sunscreens from CLINICS (I would never purchase skin care from ebay etc) in the UK in the past and BOTH contained zinc oxide.

This, from Skin Brands, the official importer of SkinCeuticals and maintainer of SkinCeuticals UK website:

"SkinCeuticals’ sunblocks provide true broad-spectrum uva/uvb protection. This revolutionary line contains z-cote®, transparent zinc oxide, which protects skin from the damaging uva rays proven to be responsible for premature signs of aging, unlike the pasty white zinc oxide sunscreens of the past, SkinCeuticals sunblocks are cosmetically elegant and all-encapsulated, which means increased protection using fewer sunscreen ingredients, reducing the chances of irritation."

You can indeed purchase the US versions of SkinCeuticals' sunscreens in the EU through clinics with dermatologists. However, L'Oreal does not market any product with ZnO (as a sunscreen agent) sold through other channels in the EU.

[jep]

Right, and as they only sell through those official channels, your statement that they don't use zinc oxide in the EU is not entirely correct. They may not be "produced here" but they are used here.

I am truly puzzled by some of your comments on zinc oxide over the past few months. You constantly state that zinc oxide is not used in sunscreens in the EU, yet, I can think of many sunscreens that are made in the EU and for the EU market that contain the ingredient. It may not be officially approved, but it is indeed used. Lavera, Clarins, Avene, Melvita, Bioderma (just to name a few) all produce sunscreens, some of which use zinc oxide as one of the UV protective ingredients.

Most sunscreen producer in the EU will try to avoid ZnO in products marketed in the EU. The reason for this is that ZnO is not approved as a sunscreen agent in the EU. Hence as a manufacturer you will not be able to claim SPF nor UVA protection. So why use it when companies do work on a budget? (ZnO is a very expensive ingredient and contributes little to SPF and there are UVA filters that are much cheaper and get those numbers up on the PPD rating AND approved as sunscreens in the EU). Hence very few companies will use ZnO in their sunscreens. The only exception is of course sunscreens that either are meant to be sold through clinics with dermatologists (they usually prefer sunscreen with ZnO) and in products that are aimed at children or sensitive skin (Avene, Bioderma).
But generally ZnO is not used in EU sunscreens. It is a pity though since it is an excellent broad-spectrum UV-protector that is well tolerated and has additional benefits: cosmetically elegant, antibacterial, soothing etc.

just to kind of silly, yet it might actually work, Forrest Mims III published a paper where he discovered that about a quarter of UV radiation absorbed at his detector is actually reflected from the ground. Do you think UV absorption coating beach sand at popular tourist areas could reduce photoaging as well as give these areas a particular advertising feature to attract visitors?

Venice beach, now 25 pct less photoaging than any othe CA destination!

some tourist places actually import sand, so they could import a sand made from a mineral that just happens to absorb UV.


then coming soon, the personal distant hovering UAV that always keeps a 100 pct UV filter between a person n the sun at about 300 meters up


here is an actual question, are there any chemicals that have higher UV absorption, the more UV they get? chemically this seems possible. rather than bleaching or deactivating, they would shift towards actually being more absorptive. put really simply, some things bleach at the sun, yet some kinds of paper "yellow or tan", what if theres a way a chemical could "yellow or tan" only at the UV range.

if you know of any such chemicals those would be nifty to nominate to study as to physiological harmlessness then they could be used without reapplication. some kind of nanosilver (photochemicals turn more absorptive with light) might work

Thank you for this very interesting input! Indeed it is an excellent idea to do something with the reflection of UVR from the ground, water etc.

I do not know of any chemical that would shift its absorption curve in the presence of UVR. Although it is possible that there are some naturally occurring mechanisms in plants that can have this.
All the approved UV-filters in the EU, US, Japan, AU have a stable absorption curve. Some does have two peaks in the range of 320-400 nm. These are the newer type of UV-filters like Tinosorb M and Mexoryl XL.

Thank you Mia for posting the thread. These sunscreens were recommended as non-whitening, non-greasy, affordable and available in the US. There are far better sunscreens than these out there. But it always depends on what is the purpose of the sunscreen. Daytime, outdoors activity etc.

Which far better sunscreens out there do you recommend except for Obagi og Burnout?
They do not have to be from the US they could be from anywhere.

One last question, before I head out:
Besides, Obagi Medical Nu-Derm Sun Shield and Burnout which other sunscreens would you recommend?

To recommend a sunscreen available in the US is not that easy I have to admit. I do not know all the products available. But the few I know and I personally like would be MDFormulation Total Protector SPF 30 (7.9% ZnO, 7.5% OMC, 4% OS). It might not be the greatest of them all but it is an extremely light sunscreen with a very natural finish. No whitening. Fragrance free. Could contain more anti-oxidants though. (It's about $ 22 for 75 ml). Packaging: tube. It is definitely non-greasy but somewhat waterproof.
The other one I really like is MAC Studio Moisture SPF 15 (6.9% ZnO, 3.5% OMC). Fantastic consistency, very good anti-oxidants. The only drawback is that it is lightly fragranced. (It's about $ 30 for 50 ml). Packaging: pump. It is definitely non-greasy nor waterproof.
The third one is actually Clinique Even Better Hand Creme SPF 15 (3% AVO, 5% HS, 5% OS). It is marketed for the hands but it does contain some very good anti-oxidants in a white fragrance-free emulsion that is hydrating enough for normal skin and has a very natural finish on the face (it is far too light as a hand creme though!). (It's about $ 35 for 75 ml). Packaging: tube. It is definitely non-greasy nor waterproof.

The "far better sunscreens" were recommended for these sunscreens MDFormulation Total Protector SPF 30, MAC Studio Moisture SPF 15, Clinique Even Better Hand Creme SPF 15. So Obagi Sun-Shield SPF 50 is a far better sunscreen then the ones above mentioned.
Again, sunscreen will depend on the purpose of use.

Hi,
Would it be possible that the sun can get to me through UVA, UVB and perhaps skin moles if I do the following:

Let’s say the sun is strong outside, I don’t want to go outside in the sun, but at the same time I would love to get som fresh air into my room. So what if I open the window in the parallell next to me. The two rooms would have a felles gang mellom seg. Then I would get the fresh air and the sun would not shine directly at me. If the sun would get to me here then it would have to go through the end of the room parallell next to me and then switch direction.

I painted this just for fun so that it would be easier to understand, even though I am really bad at paint:

The open spots signals that it's a opening.


Thanks in advance
