    @Peter I have no allergies to mineral oil, i was merely concerned about what Dr Lens said in in the video

    • tip: fastforward to 15:13 for the bit about mineral oil.
    I agree with you regarding the listing of ingredients in random order. 
    This “white washing” sometimes is quite misleading. 

    listing ingredients of higher perceived value higher up the list whereas listing ingredients like preservatives lower down the list … sneaky
    I refer to a Korea vs USA way of listing ingredients. See this

    @Peter Could you explain what your criteria photoallergenic mean?

    Your skin can show an allergic reaction under influence of sunlight in combination with external substances like sunscreen actives, from all allergic testings it appears some uv filters give more problems than others (benzophenone-3 is a common one). Maybe you can search the following terms on google: PACD, photoallergic reaction, contact allergy, sunscreen. Many articles will explain what you want to know.

    @ preciousia – I actually live on the East Coast of the US. Our climate is very moderate here, not terribly hot in the summer and not terribly cold in the winter.  We have traveled to some very hot and humid climates and I found the Blue Lizard to be just as good a product in those situations as it is here.  :)

    @Peter,

    Thank you for your suggestions about sunscreen products, such as uncover and derma. However, it seems it is unaccessible to these European products for American people. Do you have any recommendation sunscreen that could be easily accessible for American?

    @preciousia 

    As far as I can see the data in the article is complete. You may have noticed that Zinc Oxide is not allowed as UV-filter, just like some older filters like PABA and Cinoxate.
    Well, the products from Paula’s Choice are not bad. 
    And also the following products are oke I think:
    – Coola Matte Tint SPF30
    – Neostrata Sheer Physical Protection SPF50
    – MD solar science Mineral Creme SPF30
    – DermaQuest Sheerzinc SPF30
    But if you have INCI-lists I can check them for you.

    This is what they said about he moisturiser containing lemon
    “According to our medical team, it is unlikely that citrous limon will cause photosensitivity, firstly due to the minute amount that is in the formulation and secondly due to the fact that this product is a sunscreen, so hypothetically speaking, if citrous limon was photosensitising, the effect would be attenuated by the sunscreen.”

    First of all that’s complete nonsense what they say about the lemon extract, if it’s photosensitizing (which it is) it will cause problems under influence of UV-light.

    Well I don’t know what the following ingredients are: Exasperse Black R3619 , Exasperse Brown R3622 , Exasperse Russet R3236 , Exasperse Tan R3620, Exasperse Yellow R3235, so I can’t say much about that. 
    The other ingredients seem to be okay, although Diazolidinyl Urea isn’t a very good preservative.

    @Peter yup… hogwash indeed! Citrus ingredients even at Low % will affect photo sensitivity

    Koreans use lots of weird ingredients we are unfamiliar with in the Western world!

    Preservatives are necessary… I don’t know much about them tbh. Personally I use phenoxyethanol in my DIY as I noticed them used in my derm’s products. Not for the purist but easier to formulate with than the “natural” preservatives

    Looks like only the moisturiser has Urea… so the other 3 are ok

    I am not sure how I feel about their Zinc Oxide that isn’t coated tho the Australia TGA says it is safe

    Urea is actually a good ingredient, Diazolidinyl Urea is a formaldehyde releasing preservative, something you don’t want in your cosmetics. Phenoxyethanol is actually allowed in “natural” cosmetics.
