    As far as I know most make up powders use pigment grade titanium dioxide, meaning non nano. But there are also powders where they list titanium dioxide [nano]. I haven’t seen many studies where they follow a large group of persons for several years, most studies only last for 2 weeks to 6 months.

    Unfortunately we don’t have that many options of fragrance free physical sunscreens in Europe. Maybe Tinosorb M is the best hybrid, it absorbs some radiation and scatters/reflects some.

    yes i did notice that Europe has more chemical sunscreens.

    @Peter If you like, i can find an Australian pharmacy that will ship overseas. (after i tried and tested their products of course)
    tbh. mineral is best. no heat = less problems for pigmentation.
    and the ones i use are fragrance free. There is a website i use that sells many “healthy” sunscreens. They deliver worldwide and postage is free if you buy over USD40, their prices are really fair and i have been a big sucker buying many times from them. Quite a few of my skincare products come from this website recently. You can also buy the Innisfree sunscreen from them.
    I just click buy on Curel. It’s going to be a trying summer, out in the heat during peak hours with the family on vacation. :( boy oh boy. i am going to be testing 7 sunscreen samples + 2 new ones on the way + 10 sunscreens i already own. In search of the HG sunscreen.

    @RandyS Yes… that’s what your podcast said! I’m been studying up TBB. I don’t see how they “hold” or form a barrier… so easy to rub off. It’s $60+ for the SPF50+ …. good money in suncare that are makeup compatible

    I’ve ordered some products from england and america before, but most of the times its hard. In The Netherlands we pay by iDeal, most other countries only except visa or paypal. And after paying a lot for shipping and the product itself, most of the times I was disappointed, because it left a white cast, was drying or had an unpleasant texture. The Coola Mat SPF30 tinted, was almost perfect, no white cast, easy to apply, great ingredients. But the texture makes it impossible to apply enough, and it was very drying to my skin. 
    The powders are safe and don’t contain irritants. Although for UV-protection it doesn’t work. I don’t know where I’ve seen it, but there was a study where they measured the UV-protection from powders and foundations. With normal application a consumer would end up with a SPF of between 2-3, from powder/foundations with SPF30. So if you have oily skin it’s great for mattifying, but for sun protection you need a sunscreen. The study even found some moisturizers with SPF didn’t have the right texture to form a sufficient film thickness on the skin, while with products formulated as a sunscreen certain ingredients may help to get sufficient film forming (like Aluminum Hydroxide and polymers for example).

@Peter

I’ll be happy to guinea pig and do swatch test and feedback on the texture / if sticky / white cast etc of all the sunscreens i will be trying.

I have been using my dermatologist’s sunscreen for over 10 years. One brand. So there’s a lot of sunscreen to try but only one face. If you really want to try something. i will be happy to mail you a sachet in the post, a sample of the sunscreen sealed it in a mylar bag :) With compliments. If you like it, you can get it from anywhere, if not. no worries. i understand what it’s like to buy a whole bottle and not like the product (kind of what i am doing with my Moogoo… dreading)

TBH most mineral sunscreens are awful in texture, white cast! Nothing. not even the “invisible” ones are really invisible. They “reflect”. Some girls who are really fussy have special “day foundation” and “night foundation”… erm the diff is no flashbacks when camwhoring.

Coola is a very good brand. (i never tried) It really depends on what you define as white cast. If you see the Babo Botanicals swatch i did, is that acceptable?  I am pretty fair. MAC NC15. So it’s easy when buying makeup, i’m usually the lightest shade, and sometimes the lightest shade is too dark for me :(

I found moisturisers with sunscreen good for layering but NOT good as the main source of sunscreen.

My dermatologist always say.. get the sunscreen. not the multi-purpose product.

i refer to Almay new marketing campaign, digging at the Korean 10 step routine.

no way i am using their product for all my needs. Jack of all trades…

Preciousia! 

Thank you so much! I don’t know why but now that I can access your blog, I can’t see the photos. But I shall look out for the Curel and Babo Botanicals. I do like the Badger sunscreen that I got, just that the white cast is horrific. If I apply a very thin layer (gotta forget about the 2mg/cm2) I kinda can get away with it though. BUT, the quest for the perfect sunscreen never stops. And just like Peter, I’m sick of spending so much $ ($60 is a lot to me) to order something that I can’t/hate to use it. Sigh.

Maybe Wix is telling me i have used up my “free” bandwidth, i have been having issues with speed with the “free account” i have. 

doh!
need to pay them…. 
Don’t get Curel yet… i have one on the way… i’ll test it and do a patch test to share so you can see for sure if the color /white cast is ok.
Badger is not a makeup friendly sunscreen but a very good sunscreen.
anyway .. what s 2mg/cm2? they calculate 1tsp (5ml) for the neck and face… for the death of me i can’t even use up 1/2 tsp let alone 1 tsp! maybe i am using 1/4tsp at best.
my face is smaller than the 1 tsp they calculate (average man’s face) so how would we calculate the quantity used? face size in cm2? hehe. this is too technical for me.
@escherichia yes i totally agree with wasting money on products you don’t want.. and can’t bear to toss. Fortunately i did a swap with someone in Sydney for the Moogoo sunscreen (she didn’t like it) and there were no testers in the store, no reviews either. I swapped it with something i don’t use. As it came in an airless bottle, i was ok with it. normally i am a germaphobic. Cost only AUD$3 to mail a sample sachet. Would be happy to share… anyways. Babo is only USD17 a tube. Postage is free.

Cotz is another brand i am looking out for. Not expensive. Lots of budget options in my list i shared.

Preciousia,

Thank you so much! My friend is going to Japan in October 21 so I’ve asked her to get me a bottle of that Curel UV if she sees it in the drugstores. If you happen to test Curel UV before then then, pls kindly let me know. :)
Perhaps I should swap my sunscreens away too. I have 3-5 brand new sunscreens (seal not even broken) and 1-2 suncreens that I’ve tried but don’t like. But I just hate the fuss of shipping… buying bubble wrap, wrap, buy envelope, go PO… u can see what a lazy person I am LOL.
And you know what? I totally agree with you on the 2mg/cm2. I was quite fanatic about it and upon someone’s suggestion on reddit, I tried to use saran wrap to measure my face. It’s not gonna be totally accurate but the wrap is soft so it’s easier to measure, and you can always accommodate for extra. I cut out the saran wrap rectangle (more surface area is better than less, right?) and my face (I don’t really care for my neck…) is about 600cm2. I didn’t weigh my sunscreens (density matters) but going by the 2cm/cm2, I really do need about 1/6 to 1/4 teaspoon.
And that’s A LOT. Yes, I suppose I can do it in 2 or 3 layers but for pure physical sunscreens, no matter what I do, I’m gonna look like a freaking ghost (I envy you people who can take chemical sunscreens).
So I gave up. I rather apply a thin layer and get SPF5 then go out with no SPF. 
I tell myself, at worse, I will look like a spotted hag when Im 60 (well, I might not give a s**t about how I look then). Hopefuly, no skin cancers…
I’m gonna go take a look at the Babo botanicals sunscreen now.

@escherichia By the way, your comment has prompted me to shell a few bucks and pay Wix for their hosting. 2GB of bandwidth. it is a little faster now. i hope. i am fond of how user friendly they are. i don’t have to worry about backing up as well. there are limitations of course.

If your friend is going to Japan, it will be good. i know lots of Japanese products to recommend if it is along the way for them. 
Actually, postage from Australia to overseas is insane for any bottles. I am suggesting only sachets like a 5ml sample perhaps. (that way i pay the costs of postage for a Christmas card)  A sachet will allow for patch testing and color etc… I don’t mind mailing things out… it’s the costs of postage that is not worth while. would be better buying from the sources i mentioned. probably cost the same. lol
from here to Canada cost AUD$16 for a 500g bag. 
This is how much Babo Botanicals i applied on my face.lol trying to aim for 1/2 tsp
looks familiar? 
Get a SPF50… apply half and get SPF25 which is 96% protection :) or even at a quarter it is 92%
or a SPF40 halved is SPF20 which is 95% or quarter SPF10 is 90%
either way. get protected! and reapply!
