    ok. pm me about what kind of japanese products u want so we stay on topic here. lol

    Japanese sunscreens there's only one that is pure mineral and majority have alcohol in them!
  • Haha the video is cute, especially the model. :D

    Now I know why all the Korean and Japanese middle-aged ladies are always decked out in big ugly hats, long pants, sunglasses and even sleeve protectors (u gotta google this; ugly but prob useful for arms). Gotta keep the sun out! LOL
  • Applying 1/4 teaspoon is indeed a lot. In theory spf goes logarithmic so applying half means 1/4 of the spf, applying 1/4 means 1/16 of the spf. But from what I've heard in real life its more something like a third for every time you reduce the amount by half. Although I really try to apply a lot I think I apply something like 0.5-1 mL, so not the recommended 1.25-2.5mL

    imageMaybe you can place swatches of sunscreens on your site? Up till now I've tested around 60 sunscreens, but I haven't found the perfect one yet. Some have great ingredients, but I don't like if its really white. I also have swatches of sunscreens, but I don't know how to post pictures here..
  • Peter! I was just thinking about the same thing! That it'd be great if people can put swatches of sunscreens they have on their hands/faces.

    We can go on and on about the % but honestly, no one wants to look like a mime character when they are out. I actually saw a Japanese video that recommends patting on the sunscreen instead of rubbing it in. I was like, that's gonna make the white cast more obvious... but yes, it's all about creating that protective sunscreen film isn't it? Sigh.
  • Yes, if the products is white it's white, you have to try to get the recommended amount. That why I l like sunscreen actives like Uvinul T150, Uvinal A Plus, Tinosorb S (not M), Uvasorb HEB, they are not extremely white on skin. Tinosorb M and Uvinal A Plus also offer extremely high UVA protection.

    What I do, I apply a reasonably thick layer on my hand. Let it soak in for about 30 minutes and then look at it under various angles under normal daylight, especially indirect daylight really shows if the sunscreens leaves white cast. Also wetting your skin a bit shows if the sunscreens is white. In my opinion that's the best way to see if a sunscreen has a potential to be white in an extreme situation. Also applying it to one half of your face helps to see what difference it makes. Applying it to your whole face and looking at it with artificial light makes it very difficult to see if it's white, and many times I had been looking like a ghost during the day without realizing, because you only see it under specific lighting. Then I have tested many sunscreens for about 4-5 weeks on one half of my face to see how my skin reacted. But after a dozen sunscreens, I haven't found the perfect one yet. Although from what I've testes so far I like the Uncover Skincare Suncare SPF30 best for its ingredients, I've never seen a sunscreen with such good ingredients (Tinosorb, 3% Niacinamide, 1% Green Tea extract, 1% Vitamin E), but it's extremely white on skin. And I like the Danish brand Derma Sollotion SPF30 best because its completely invisible on skin, the only downside it's slightly shiny and it only contains Tocopheryl Acetate (vitamine E). I also like the combination of Paula's Choice Skin Recovery SPF30 + Paula's Choice Resist Super Light SPF30, because in combination it's not white, not shiny, easy to apply, and it only contains physical sunscreens, the downside they do use nano particles and I believe the concentration of antioxidants is rather low. 
  • Now I am tempted to get PC's SPF 30 sunscreen. haha
  • @Peter.. yup. i will review and place swatches on my site. since you know i am NC15... the white cast don't show up as much as for darker skintones. but if it is white.. i'll tell you it's white... too white for me is a NO GO for you guys hehe.

    Well you can say what you want about Paula's Choice products, but in general most of them don't contain irritants and she makes many different textures. The Resist Cellular SPF25 only contains Titanium Dioxide and is too white for me. The Calm for oily skin is okay on its own, but because its white I need to apply something over it, the Resist Super Light SPF30 is tinted, but really ment for extremely oily skin. Applying the Calm for dry skin/Skin Recovery SPF30 first and then the Resist Super Light was a reasonable combination for me.
    Guys prefer invisible sunscreens ;-) otherwise you have to use foundation or powder to counteract the whitecast and although I even accept using it sometimes, it can create weird moments if someone touches your face or rubs a towel on your face and make up comes off...But I will check your site..
  • Maybe i am a girl. I don't mind to apply anti-oxidants as a serum prior to the sunscreen. it's really hard to find the "perfect sunscreen" because there is none.
  • Hi Peter,

    Erm... I wasn't bashing PC's products? In fact, I haven't tried any of them before and I'm interested in it...

    @Peter i know men. my hubby wants no fuss. A wonder product to do it all.

    my dermatologist private label sunscreen is really really nice. i just got wandering eyes to look. his costs $60+ for 50g. Derm has sold his practice and retired, so i don't find any affinity to the new owners. They have hiked their prices too. Also i got burnt using their older SPF30+ products (not suited for Australia sun) The new SPF050+ product now is much nicer and user friendly.

    the best way to counter the white cast is to add a tint. however getting the right tint is mighty difficult!!!


    i don't like titanium dioxide as the sole sunscreen, because it is not good with UVA1 coverage, only UVA2 :(

    i tried this... and my indian friend tried it.. we both reported color compatibility. she is fair for an indian, maybe a NC35?
    image
  • If your indian friend can use it, I think I'd have no problems haha. But you were okay with it? I mean NC15 and NC35 are pretty different...?
  • I don't know anything about 
    Tasmannia Lanceolata (Mountain Pepper) Fruit/Leaf Extract
    Polygonum Aviculare (Knotgrass) Extract

    But the it looks very good on skin
  • @Peter WOW 1.2 tsp is a lot. the hyperlink works! :D

  • no I didn't mean you were bashing Paula's Choice :-) I only said it because you hear many people on the internet saying Paula's Choice isn't organic, and that she uses "chemicals" and so on. But I think her products are fine. Organic menthol, fragrance or citrus extracts aren't that good for skin @preciousia well I want a sunscreen that is tinted, or is invisible on skin, I don't like to apply foundation and powder, although maybe it's unavoidable I don't know. But I don't mind using a cleanser, toner, exfoliant, antioxidant serum, a tretinoin product and seperate moisturizer, so I'm not the kind of guy that only wants 1 product to do it all ;-)

    escherichia  i have no idea what her MAC shade is.. i am just guessing. it can even be NC45... lol but she is indian alright!!!

    i don't think you can use the Cancer Council one though despite the high 20% zinc. if you like i can pop a sachet too so you can try. i really like the ingredients in this one. B3+E+Aloe+ Allantoin+ B5!
  • @Peter I think you'll like a lot of the "healthy" aussie brands. they really don't like to include the "nasty" ingredients.

    and alot of weird Aussie native botanicals that no one has heard of either. hee

    I love Paula Begoun. I have her book!  :x
    @Peter : You are more diligent than my hubby. He spends more time cleaning his LPs than his face :P
  • Peter,

    Ah I see! I actually don't care if a product is green/organic (sorry heh). I don't even believe in the organic hype for foods/ingredients. While I'm not a chemist, I majored in biology so yep, I actually think PC's products are very well-backed up in science, at least. Some of PC's opinions are a bit outdated (like the NO to fragrances issue) but in general, her products look good. It's just that I'm in Canada and don't have easy access to it (as in, brick and mortar stores). Sad. sigh.

    The Swisse one is only AUD$25 for 60ml that's about USD19
    https://www.priceline.com.au/swisse-natural-defence-bb-cream-spf30-60-ml

    and even though it is not TGA approved. our NICNAS are toughies too. 

    An American company failed to get their oure mineral SPF50 primer approved. (wont mention names) so it is sold in USA with SPF50 and in Australia. nothing. not even spf30 
  • Preciousia,

    From the picture you uploaded, the Cancer Council really looks pretty white heh. After having swatched so many high ZnO sunscreens on the back of my hands/jaw... I can tell just from looking if the sunscreen would be too white for me lol. The Pure Mineral BB cream looks better but pretty dark eh. I have several BB creams (Etude House, Skin79, Coogi - sadly discontinued, ah so sad, this is my HG) so don't worry about it!! :)
  • edited October 2016
    escherichia  if it is too dark, just mix it with your too white sunscreen lol

    the cancer council one is pretty see thru' not so much coverage.. if you get what i mean. enough to tint the zinc but not enough to use as bb cream. it is marketed as tinted sunscreen only.
